Nordic spring storms

The first three weeks of March saw areas of low pressure repeatedly cross Norway from the North Atlantic, coming in from the Norwegian Sea across to the Barents Sea. These storms brought with them warm and humid/moist air from the south west. None of these storms was especially strong/powerful.

Jorun (Norway)

(unnamed by FUB) In early March high pressure built over UK and western Europe for first time in months (since December), directing the Atlantic storm path to the north. An area of low pressure designated extreme weather and named Jorun by Norwegian Meteorological Institute on 8 March 2014. http://www.yr.no/nyheter/1.11591592 http://www.met.no/Ekstremv%C3%A6ret+Jorun+kommer.b7C_xdjQ1n.ips Finnmark, northern Norway expecting winds 30-40m/s to coincide with the start of the Finnmarksløpet dog sled race. http://www.nordlys.no/nyheter/article7216299.ece high pressure steering lows into the Norwegian Sea, rather than into Europe.http://www.nrk.no/nordnytt/bolighus-far-strommen-tilbake-1.11593025 affected parts of Troms and Finnmark with a westerly full to strong storm. Jorun brought hurricane strength winds of 40 m/s to the mountains at Banak, and wind gusts stronger than could be measured, highest recorded at 51.4 m/s (100kt). The low moved over the Barents sea filling as it moved eastward.-http://met.no/Ekstremv%C3%A6ret+Jorun+er+over.b7C_xdjQ2o.ips

Kyrre (Norway)

Another extreme weather event named by Norwegian Meteorological Institute as Kyrre affected north (Nordland and Troms) Norway on 13-14 March with extreme precipitation and wind. Up to 90mm fell in 24 hours, flooding, landslides and closing roads in Nordland and Troms. -http://www.nrk.no/nordland/stormen-kyrre-velter-traer-og-biler-1.11605805 two people hospitalised after wind blew a bus off the road in -http://www.nrk.no/nordland/to-personer-i-observasjon-1.11605533 -http://www.nrk.no/sognogfjordane/ingen-_all-right_-natt-og-kveld-1.11605613 close to Hurricane force winds-http://www.yr.no/nyheter/1.11605496

From the 24 March an area of high pressure began to build across southern and mid Norway.

March synopsis

In the UK early March witnessed the end of a remarkable river flow runoff episode as outflows from Great Britain fell below average (for the time of year) for the first time since the third week of December. During this period, the 90-day average outflow exceeded the previous highest, in a series from 1961, by an appreciable margin. In March 2014 some parts of eastern and central England recorded sequences of 15 or more days with precipitation largely restricted to fog-drip and accumulated totals less than 1mm.-http://www.ceh.ac.uk/news/news_archive/march-2014-uk-hydrological-summary_2014_18.html and http://www.ceh.ac.uk/data/nrfa/nhmp/hs/pdf/HS_201403.pdf

Storm

UK Met Office winter 2014 (1 December 2013 to 15 February 2014) was the stormiest winter since 1993 in the UK. UK Met Office noted the period from mid-December 2013 to mid-February 2014 saw at least 12 major winter storms, which, when considered overall, this was the stormiest period of weather the UK has experienced for at least 20 years. the storms of Dec-Jan were major winter storms, but not considered individually exceptional during a winter season, with severe recent examples recently being 3 January 2012 (Andrea) and 8 December 2011 (Friedhelm). It was the so-called "low factory" of rapid succession of lows, which made the winter exceptional. Pressure readings below 950 hPa are rarely recorded from land stations. Series of lows developing or forming as storms over North America explosively deepening over the Atlantic/gulf stream before reaching European coast. Ireland saw the worst storm on February 12 last when winds gusting up to 86 knots (160kmh) were recorded at Shannon Airport. The distinguishing feature of the winter weather was the "seemingly unending series" of Atlantic storms which crossed the county, Met Eireann's winter weather bulletin noted.

Omega block developed over northern Norway/Scandinavia which prevented lows moving east over Europe, series of lows "dying" to the northwest of Britain and Ireland.

Research carried out showed that this was the stormiest winter on record in the United Kingdom and Ireland. The scientists used long-running atmospheric datasets to characterise winter storminess over the North Atlantic for the last 66 years and as far back as 1871-1872 for Ireland and Britain... however, when the frequency and intensity of storms were combined it was concluded that no year in the 143-year record endured a winter as severe as 2013-2014. The data we used covering the north Atlantic goes back to the winter of 1948 and 1949, but it goes further back in Ireland and the UK to the winter of 1871 and 1872.Records from Met Eireann show that more than half of all weather stations recorded their wettest winter on record, with the worst storm on February 12 last when winds gusting up to 86 knots (160kmh) were recorded at Shannon Airport.There was widespread flooding across the country, while water supplies were severely disrupted as power lines were downed.

Wind

In general peak wind speeds not exceptional, as storms reached peak intensity over Atlantic and were (mostly) diminishing at landfall.high wind speeds mostly up to 60 miles per hour (97 km/h) in urban areas, with peak gusts in exposed coastal locations exceeding 90 miles per hour (140 km/h). Strongest storm in wind was St Jude Storm in October damaging winds in Southern Denmark and Northern Germany, with damages also in UK, Netherlands and Sweden.

Anne storm waves were not particularly unusual for the northeast Atlantic, but the storm’s path followed a relatively low-latitude track, pushing the bulk of the wave energy toward the southwest of Ireland and England. Peak wave periods were exceptionally long (even compared with storms of similar wave height occurring in December), and enhanced the impact of the waves at the coastline. The combination of significant wave height and peak period is likely to mark the storm as a 1 in 5–10 year event in the southwest of the U.K., based on wave conditions experienced over the last 30 years.

DWD report.

The 110-km long Gironde coast, SW France, was exposed to the most energetic wave conditions seen over the last 18 years. The winter 2013/2014 storm waves caused unprecedented beach and dune erosion along this coast. The high-energy normally-incident long-period swell produced by the "Christina"/"Hercules" storm was outstanding.

From early December 2013 to February 2014, the southwest coast of England was battered by an unprecedented run of major winter storms. NERC analysis of wave data suggests that the storms were the most energetic to affect the southwest coast of UK since 1950. and thus represents at least a 1:60 year event.-http://gtr.rcuk.ac.uk/project/621BCA5B-3CF5-40FA-8ABE-6ED4372C1FEA

You get seasons and even decades of calm, with relatively few floods, and other periods when they occur in rapid succession. 2013-14 was a particularly unusual season, in that seven out of the 96 events in the 100-year database occurred during this period; no other season has had so many large floods in the last century. Two of the events in 2013-14 (5-6 December 2013 (Xaver) and 3 January 2014(Christina)) rank in the top ten for sea-level height. Both also rank highly in terms of spatial footprints - that is, they struck very long stretches of the UK coast.

Perils AG, What was not so exceptional, Even if from a meteorological perspective the past winter can be considered exceptional, it was not in respect of the resulting insured losses. Based on the events investigated, PERILS estimates the total insured property loss from the storms and flooding for the period from the end of October to the end of February to be EUR 3.6bn. This figure is significantly below the EUR 10.1bn loss which was experienced in 1999/2000 (Anatol, Lothar, Martin; PERILS estimates).

Winter flooding of 2013–14 on the Somerset Levels and Moors were particularly badly affected as floodwaters inundated an estimated 6500ha of land, with drainage hampered by high tides.

Although the mainstream press reported record rainfall through much of England and Wales, with headline-grabbing coverage of flooded properties in the Somerset Levels, Severn Valley and Thames Valley, flood losses from winter 2013–2014 were not exceptional. About 17,500 flood claims in England and Wales, 9000 from homeowners from early December 2013 to March 2014, according to the Environment Agency this level of flooding is not exceptional, even in terms of events in the last decade.

7000 properties were flooded during the winter, comparable with the 2012_Great_Britain_and_Ireland_floods but significantly less than the 55 000 impacted properties during the summer 2007 United Kingdom floods.

This compares to the 2007 floods which resulted in at least 55,000 residential and business claims. Based on an analysis of the events at the time, RMS estimated the insured loss for the two main U.K. flood events of 2007 United Kingdom floods 2007 to be: £1.25–1.75 billion ($2.1–2.9 billion, assuming 2014 currency conversion rates). More recently, the 2012 Great Britain and Ireland floods 2012 U.K. floods led to the second highest annual insured flood losses in the U.K. since records began.

Starting last fall, the polar jet began repeatedly following a route over North America that took it over Alaska and western Canada, and then brought it swooping down like a roller coaster over the Great Plains and the Midwest. There it bottomed out and climbed steeply north. It’s not that these ridges and troughs, these dips and bumps in the jet stream’s path, are uncommon. What’s unusual is for the dips and bumps to linger in the same place for months on end.

1993 Season.

1990 Season In contrast, the damaging windstorms of early 1990 were immature systems at landfall, with much potential to cause damage on land (Figure 2). Their tracks were generally farther south and the storms were still intensifying when they hit land (reaching their nadir points well to the east of landfall).

During the period September 1982 to March 1983, about a dozen depressions in all deepened to 950 mbar or below over the north Atlantic.

A similar long succession of very deep cyclone centres arising at intervals of only a few days occurred on the North Atlantic in December 1942.

While previous winters saw more storms, for example in 1914 and 1915, and ones which were more intense, such as storms in the late 1980s and early 1990s, no year in the 143-year record endured a winter as severe as the last one, when the frequency and intensity are combined.

new study shows the jet stream pattern that brings North American wintertime weather extremes is millennia old – "a longstanding and persistent pattern of climate variability," Based on what happened in past millennia, that could make a curvy jet stream even more frequent and-or intense than it is now...They found that the jet stream pattern – known technically as the Pacific–North American teleconnection_pattern – shifted to a generally more "positive phase" – meaning a curvy jet stream – over a 500-year period starting about 4,000 years ago. In addition to this millennial-scale change in jet stream patterns, they also noted a cycle in which increases in the sun's intensity every 200 years make the jet stream flatter.http://phys.org/news/2014-04-west-cold-east-year-pattern.html

Thames high flows, highest since 1974. exceeded only 8 occasions in 132 year record, usually associated with lower temperatures when snowmelt over frozen ground lead to high surface runoff ie 1947 Thames flood.

Hurricane Debbie Night of the Big Wind The more recent storms of 26th December 1998 and 24th December 1997 were also of greater intensity.

Yet the Met Office’s own records showed there had been even more rain between November 1929 and January 1930, again long before we ever heard of ‘climate change’. In England alone, the 15.6 inches (396mm) of rain which fell in the winter of 2013-14 — claimed by Dame Julia to have been the most exceptional period for more than two centuries — was significantly exceeded by the 19.5 inches (495mm) recorded between November 1929 and January 1930. In fact, that rainfall two years ago turned out to rank as only the fourth heaviest three-monthly rainfall figure since the Met Office record began in 1766, below those recorded in 1929-30, 1960 and 2000.https://notalotofpeopleknowthat.wordpress.com/2015/12/10/booker-on-the-cumbria-floods/

Nth Am Cold Wave

proximal cause... Dr Tom Matthews from the Department of Geography at NUI Maynooth said the extreme weather was caused by cold air from the polar ice caps which spread into North America. Conditions were perfect for creating storms as it moved across the warm north Atlantic ocean, "The conditions we experienced were related to what was going on upstream over North America."High winds and high precipitation (rainfall) events are caused by low pressure, or cyclones.

SSW

Media reports of an over apossible SSW event beginning and a NOAA climate.gov blog post in early January 2014 originally attributed the breakdown of the polar vortex to a Sudden stratospheric warming event, which did not actually develop. The 2013–14 North American cold wave could not be linked to sudden stratospheric warming as had been the case in other harsh recent winters in the northern hemisphere such as during 2009-10 (Winter of 2009–10 in Europe), and (Jan 2013). Mechanism proposes to slow or even reverse the flow of air in the upper atmosphere, which flows east to west rather than west to east, which weakens the jet stream, as mechanism for cold winter weather seen in previous winters. This mechanism would not have explained the strong jet stream over the North Atlantic seen during the winter of 2013-14. http://www.washingtonpost.com/blogs/capital-weather-gang/wp/2013/12/31/sudden-stratospheric-warming-could-it-lead-to-a-very-cold-january-in-d-c/ [note no SSW occurred]

Pacific anomaly

Was the extreme storm season 2013­14 over theNorth Atlantic and the UK triggered bychanges in the West­Pacific Warm Pool?Presenting Author: Simon Wild

UK Met Office and Centre for Ecology & Hydrology Report

Released on 9 February

Quasi-biennial oscillation small but significant role in winds in Europe, during winter 2013-14 was unusually strong in western phase.

UK Met & CEH

Potential influences on the United Kingdom's floods of winter 2013/14. In some instances, such as the known decreases in Arctic sea-ice cover, this is believed not to have been a factor in the particular 2013/14 winter rainfall characteristics... This new review shows how a complex chain of events involving the Pacific Ocean and an unusual jet stream led up to this unprecedented winter.

Wang et al

The 2013-14 California drought was accompanied by an anomalous high-amplitude ridge system. The anomalous ridge was investigated using reanalysis data and the Community Earth System Model (CESM). It was found that the ridge emerged from continual sources of Rossby wave energy in the western North Pacific starting in late summer, and subsequently intensified into winter. The ridge generated a surge of wave energy downwind and deepened further the trough over the northeast U.S., forming a dipole. The dipole and associated circulation pattern is not linked directly with either ENSO or Pacific Decadal Oscillation; instead it is correlated with a type of ENSO precursor. The connection between the dipole and ENSO precursor has become stronger since the 1970s, and this is attributed to increased GHG loading as simulated by the CESM. Therefore, there is a traceable anthropogenic warming footprint in the enormous intensity of the anomalous ridge during winter 2013-14, the associated drought and its intensity. Strong and persistent area of high pressure over the north Pacific from November, dip in jet stream over eastern North America, dipole more intense as jet becomes wavier, dipole tends to precede el nino by one year, weather pattern became established during the fall of 2013, and intensified into the winter. They found it had its origins in the Western Pacific, where a series of large, slow moving atmospheric waves known as Rossby waves originated, before moving across the North Pacific other scientists cautious, as based on only one model...so absolute link to climate change not convincing, but offers an opportunity for further studies comparing models, hypothesis requires further investigation.

Arctic amplification theory

Jennifer Francis of Rutgers told meeting of American Association for the Advancement of Science Jet Stream http://www.independent.co.uk/news/science/uk-weather-high-anxiety-among-jet-stream-watchers-9131141.html http://www.bbc.co.uk/news/science-environment-26023166 resonance see2013 European floods http://www.dailymail.co.uk/news/article-2560310/No-global-warming-did-NOT-cause-storms-says-one-Met-Offices-senior-experts

climate models (mostly) agree with Francis's theory, correlate with difference between the thickness (Hypsometric_equation) of the atmosphere at the poles and at mid latitudes has fallen in recent years, which in turn correlates with data showing wind speeds in the jet stream, with the bits of the world that have the smallest temperature gradient showing the biggest drop in wind speeds. One problem is that the changes in atmospheric thickness and wind speed observed have become apparent only since the mid-1990s, which gives fewer than 20 years of data to work with. Another difficulty concerns the blocking patterns. Dr Francis’s theory suggests there will be more of them in future, as the world warms. But climate models unanimously disagree, saying that global warming will produce fewer of them... But Dr Francis herself points out that this year’s North Atlantic jet stream has in fact been stronger than normal.

sluggish, meandering jet stream proposed by Francis ...fits the pattern seen over the Pacific during the winter, Tim Woollings an atmospheric dynamics researcher at Oxford University pointed out in an email exchange that over the Atlantic the jet stream was stuck, but was not meandering or slowed where the jet has reached sustained speeds over 230 miles per hour (370 km/h) during the winter, reaching record 275 miles per hour (443 km/h) on 22 December 2013. 30% stronger than normal jet stream.

Screen In spite of mean climate warming, an ostensibly large number of high-impact cold extremes have occurred in the Northern Hemisphere mid-latitudes over the past decade11. One explanation is that Arctic amplification—the greater warming of the Arctic compared with lower latitudes12 associated with diminishing sea ice and snow cover—is altering the polar jet stream and increasing temperature variability13, 14, 15, 16. This study shows, however, that subseasonal cold-season temperature variability has significantly decreased over the mid- to high-latitude Northern Hemisphere in recent decades.-http://www.nature.com/nclimate/journal/vaop/ncurrent/full/nclimate2268.html http://phys.org/news/2014-06-arctic-linked-european-cold-weather.html

the Climate Prediction Center did not measure large negative AO index values during this last outbreak because the polar vortex was not weaker across the entire hemisphere—just near North America and eastern Siberia. While Canada and the eastern U.S. froze, many locations around and within the Arctic Circle including Alaska, Scandinavia, Europe, and western Russia enjoyed warmer-than-average temperatures. So the event was not a complete breakdown of the polar vortex, according to L’Heureux.2009-2010 more classic negative AO, AO NAO often strongly correlated, This latest cold outbreak was one case where they were not in strong alignment; in early January 2014, the NAO index was near zero. -http://www.climate.gov/news-features/event-tracker/how-polar-vortex-related-arctic-oscillation NOA+ days Dec and Jan Meteo France http://www.meteofrance.fr/actualites?articleId=3355213 http://www.cru.uea.ac.uk/~timo/datapages/naoi.htm Jet stream Relatively strong, persistent, occurring at low latitudesthe average Nao index* for Nov 2013 to Feb 2014 was the 4th highest in the last15 years with 72% of daily values exceedingthe average value of 0.13.

(The North Atlantic Oscillation (NAO) is not very effective as a discriminator of surge activity in high magnitude surge generation (top 1% of events) within the region of the South-Western Approaches to northwest France and southwest England.)

Wild Befort Leckebusch

One alternative potential driver partly explaining the anomalously high storm frequency in 2013/14 could have been the unprecedented anomalies of sea surface temperatures in the west Atlantic (Fig. 7.2a). High sea surface temperatures in the subtropical west Atlantic (green box, Fig. 7.2a) and low temperatures over North America (yellow box, center panel Fig. 7.1) are unrelated (the correlation equals 0.03), but when occurring concurrently, they substantially increase the meridional temperature gradient over the core genesis region of extratropical cyclones. This meridional temperature gradient is positively related S33DECEMBER 2015AMERICAN METEOROLOGICAL SOCIETY|to windstorm frequency over the North Atlantic and Europe (Fig. 7.2b). Baroclinic instability in this region can be positively inf luenced through a strong temperature gradient, leading to enhanced cyclo-genesis and potentially strong deepening of cyclones responsible for high wind speeds. Conclusion. The anomalous high number of wind-storms in winter 2013/14 over the northeast Atlantic and the British Isles cannot directly be attributed to anthropogenic-inf luenced factors as apparent in the tropical west Pacific. Very suitable conditions of natural internal interannual variability, including conditions over the tropical and North Pacific, North America, and the west Atlantic, favored the record number of storm counts.10.1175/BAMS-D-15-00118.2 https://agu.confex.com/agu/fm15/webprogram/Paper61393.html

There was possibly an additional factor, whereby wind patterns were such that a phenomenon called a “westerly duct” allowed perturbed wind patterns over the Pacific to reinforce the Jet Stream strength across the Atlantic.

The strongest sea temp losses occurred in January–February 2014, and followed a similar pattern to December 2013, with anomalous cooling averaged over these two months up to 120 W m–2. Josey, S., J.

interconnected by anomalous ocean evaporation over the North Atlantic subpolar gyre region (SPG). This evaporation (or oceanic latent heat release) was accompanied by strong sensible heat loss to the atmosphere.

Northern hemisphere snow cover

With respect to North Atlantic/European climate statistically significant correlations have been found between summer and autumn snow cover on the northern hemisphere and the NAO in the following winter.

According to data from the Rutgers Global Snow Lab, the Northern Hemisphere snow cover extent during November was 13.42 million square miles, 310,000 square miles above the 1981–2010 average of 13.11 million square miles, and the 16th largest November snow cover extent in the 48-year period of record. The North American monthly snow cover extent was the third largest on record, behind November 1985 and 1996. The Eurasian November snow cover extent was below average and the 18th smallest on record. The average Northern Hemisphere snow cover extent during autumn was 7.54 million square miles, 710,000 square miles above the 1981–2010 average of 6.83 million square miles. This was the sixth largest snow cover extent during the autumn season for the Northern Hemisphere and the largest since 2002. North America had its seventh largest autumn snow cover extent, while Eurasia had its 10th largest.-http://www.ncdc.noaa.gov/sotc/

Judah Cohen, Director of Seasonal Forecast at Atmospheric and Environmental Research in Lexington, Massachusetts, has pioneered winter forecasts that link colder Eastern US weather to years when there is more snow on the ground in Siberia in October. It’s still early and October isn’t finished, but the month has started out unusually snowy in Siberia, which points to a cooler winter for east of the Mississippi River, he said. Halpert said Cohen’s method is intriguing but NOAA needs more years to show that it works as forecast tool.-http://www.news.com.au/technology/environment/winter-is-coming-will-we-see-a-return-to-polar-vortex-conditions-in-the-us/story-e6frflp0-1227093438068

The bottom line is that a careful reading of any of the papers claiming an anthropogenic origin of the amplified upper atmospheric waviness reveals that they all have major flaws. Or the media has hyped them beyond recognition. I don't know of any leading atmospheric scientist that is claiming such a relationship. But that has not stopped the media from hyping the connection. There are, in fact, a number of papers that provide a different view, that the origin is from natural variability. For example, in the same issue as Swain et al, a paper by Funk et al looked at a large collection of climate model simulations and concluded that global warming had no impact on the West Coast ridging.-http://cliffmass.blogspot.co.uk/2015/02/the-origin-of-this-winters-weather.html

Notes

1. ^ The designation of explosive cyclogenesis by the Spinish State Meteorological Agency AEMET may not strictly fit the category of explosive cyclogenesis as the Spanish Agency calculate a 12 hectoPascals (or mbar) drop in pressure over 12 hours, rather than the strict definition of a drop of 24 hPa in 24 hours.
