Extreme Jet Stream Pattern Triggers Historic European Floods

A historic multi-billion dollar flood disaster has killed at least eighteen people in Central Europe after record flooding unprecedented since the Middle Ages hit major rivers in Austria, the Czech Republic, Germany, Poland and Slovakia over the past two weeks. The Danube River in Passau, Germany hit the highest level since 1501, and the Saale River in Halle, Germany was the highest in its 400-year period of record. Numerous cities recorded their highest flood waters in more than a century, although in some locations the great flood of 2002 was higher. The Danube is expected to crest in Hungary's capital city of Budapest on June 10 at the highest flood level on record, 35 cm higher than the record set in 2006. The flooding was caused by torrential rains that fell on already wet soils. In a 2-day period from May 30 - June 1, portions of Austria received the amount of rain that normally falls in two-and-half months: 150 to 200 mm (5.9 to 7.9"), with isolated regions experiencing 250 mm (9.8"). This two-day rain event had a greater than 1-in-100 year recurrence interval, according to the Austrian Meteorological Agency, ZAMG. Prior to the late May rains, Austria had its seventh wettest spring in 150 years, which had resulted in the ground in the region becoming saturated, leading to greater runoff when the rains began.

Floods caused by a blocking high pressure system
The primary cause of the torrential rains over Central Europe during late May and early June was large loop in the jet stream that developed over Europe and got stuck in place. A "blocking high" set up over Northern Europe, forcing two low pressure systems, "Frederik" and "Günther", to avoid Northern Europe and instead track over Central Europe. The extreme kink in the jet stream ushered in a strong southerly flow of moisture-laden air from the Mediterranean Sea over Central Europe, which met up with colder air flowing from the north due to the stuck jet stream pattern, allowing "Frederik" and "Günther" to dump 1-in-100 year rains. The stuck jet stream pattern also caused record May heat in northern Finland and surrounding regions of Russia and Sweden, where temperatures averaged an astonishing 12°C (21°F) above average for a week at the end of May. All-time May heat records--as high as 87°F--were set at stations north of the Arctic Circle in Finland.

If it seems like getting two 1-in-100 to 1-in-500 year floods in eleven years is a bit suspicious--well, it is. Those recurrence intervals are based on weather statistics from Earth's former climate. We are now in a new climate regime with more heat and moisture in the atmosphere, combined with altered jet stream patterns, which makes major flooding disasters more likely in certain parts of the world, like Central Europe. As I discussed in a March 2013 post, "Are atmospheric flow patterns favorable for summer extreme weather increasing?", research published this year by scientists at the Potsdam Institute for Climate Impact Research (PIK) in German found that extreme summertime jet stream patterns had become twice as common during 2001 - 2012 compared to the previous 22 years. One of these extreme patterns occurred in August 2002, during Central Europe's last 1-in-100 to 1-in-500 year flood. When the jet stream goes into one of these extreme configurations, it freezes in its tracks for weeks, resulting in an extended period of extreme heat or flooding, depending upon where the high-amplitude part of the jet stream lies. The scientists found that because human-caused global warming is causing the Arctic to heat up more than twice as rapidly as the rest of the planet, a unique resonance pattern capable of causing this behavior was resulting. According to German climate scientist Stefan Rahmstorf, "Planetary wave [jet stream] amplitudes have been very high in the last few weeks; we think this plays a role in the current German flooding event." More rains are in store for the flood area through Monday, then the blocking pattern responsible for the great 2013 Central European flood is expected to disintegrate, resulting in a return to more typical June weather for the next two weeks.

The northward wind speed (negative values, blue on the map, indicate southward flow) at an altitude of 300 mb in the mid-latitudes of the Northern Hemisphere during July 1980, July 2011, and the last twelve days of May 2013. July of 2011 featured an unusually intense and long-lasting heat wave in the U.S. (the 4th warmest month in U.S. history), and the normally weak and irregular waves (like observed during the relatively normal July of 1980) were replaced by a strong and regular wave pattern. Late May 2013 was also very extreme, resulting the great Central European floods of 2013. Image credit: Vladimir Petoukhov and Stefan Rahmstorf.

I'm in Granby, Colorado this week for the American Geophysical Union's Chapman Conference on Climate Change Communication. Many of the talks will be webcast live; you can see a list of the talks (times in MDT) here. My talk, "The Weather Underground Experience," is scheduled for Monday at 4:30 pm MDT. I'll give a 15-minute overview of the history of wunderground, and what I've learned about communicating weather and climate change information along the way. There is live tweeting going on from the conference, #climatechapman. My blog updates this week may be somewhat random as a result of the conference, but I'm not seeing anything in the tropics worthy of discussion at this point.

No record cold here! Average lows are around 58, supposed to be at or above 65 for the next week or longer. Oppressive humidity, but clouds and rainfall keep daytime highs in check. Flash flooding is a possibility due to the unusually humid airmass.

It's just like everything is stuck. Extreme heat and drought over the west. Oppressive humidity coupled with clouds and downpours over parts of the Midwest and Southeast. And excessive heat and humidity over the East coast.

It will be interesting to see where June checked in for the country... it should be one of the hottest on record nationwide, as most of the country was warmer than normal with extremely hot weather in much of the West. Alaska also experienced one of the hottest Junes on record. July is also shaping up to be a national scorcher. This is now the fourth consecutive abnormally hot summer. 2010, 2011, 2012, and now 2013. All should be among the top ten of all-time hottest summers. It's interesting that a Stanford report from spring 2010 just before this crazy stretch projected that by mid-century almost every summer would be hotter than the then-existing hottest summer on record for the U.S. Clearly, with the current state of things, we are very nearly there already.

I'm an Evangelical and I see why it's called "An Evangelical declaration on Global Warming" It certainly couldn't be called "An Evanglical's proof that all the scientists are wrong." I think faith and science have no problem going hand in hand. I've made, I believe, strong arguments for that in the past here. I'm afraid Dr. Spencer thinks faith and big business denialism go hand and hand. His position in this arena has been debunked because it absolutely denies all reason behind what is proven science at this point in regards to GW. I believe his heart is in the right place, but I honestly believe he's been misled/manipulated by very powerful forces and powerful misinformation and bad science. The Evangelical movement is made up of millions and millions of us here in the US alone. If Big Business can convince them GW is not happening then it goes a long way to furthering their agenda of slowing down any regulations on what they do and how much they make.

Quoting wilsongti45:
I love how this graph shows month by month global temperature anomaly. Shows the warming trend a lot better IMO. Try drawing a best fit line for the 80's, then 90's, etc. Each decade is warmer than the last and this graph clearly shows that as well as the clear upward trend in the past 15 years.
And this, mind you, is from John Spencer's falling-out-of-fashion UAH temperature data set. At any rate, here's a version overlaid with various trendlines. (The 4th- and 6th-order polynomial trendlines were added to highlight the silliness of Spencer doing using the same trendlines on his version of the graph to show "cooling". He's since stopped using those trendlines.)

uah

(Also, note that Spencer's graph shows an anomaly of 0.07C for May, while this version accurately reflects the actual measuement of 0.08C.)

SE will get the tail of this

MUCH OF THE SEVERE WEATHER WILL REMAIN TO OUR EAST
CLOSER TO THE UPPER/SFC LOWS, BUT WITH THE VERY UNSTABLE AIRMASS IN
PLACE, ANYTHING THAT DEVELOPS TOMORROW WILL HAVE THE POTENTIAL FOR
DAMAGING WINDS AND POSSIBLY LARGE HAIL. MUCAPE VALUES OVER THE CWA
TOMORROW/TOMORROW AFTERNOON CLIMB INTO THE 3000-4000 J/KG RANGE (WITH
SLIGHTLY LESSER VALUES OVER NW AL ~2000 J/KG), AND DCAPE OF
1500-2000 J/KG. THE CAP WILL BE RELATIVELY WEAK (CIN ~15-20 J/KG),
AND WITH STEEP LAPSE RATES IN PLACE (AND WET BULB ZERO HEIGHTS
LOWERING TO ~10KFT), LARGE HAIL IS THE SECOND THREAT TOMORROW.

-hun


. A HEAT ADVISORY MAY BE NEEDED
TOMORROW AFTERNOON...ESPECIALLY ACROSS THE SOUTH. MODELS CONTINUE TO
SHOW QUITE AN UNSTABLE AIRMASS AHEAD OF THE FRONT WITH CAPE VALUES
OVER 4000J/KG AND BULK SHEAR OF 25-35KTS. THIS WILL BE ENOUGH FOR
STORMS TO DEVELOP...SUSTAIN UPDRAFtTS...AND POSSIBLY BECOME
ORGANIZED. 500MB TEMPS ARE RATHER WARM AROUND -7C...BUT STEEP LAPSE
RATES AND DRY AIR ALOFT WILL ENHANCE THE LARGE HAIL THREAT. ADD IN
DOWNDRAFT CAPES UP TO 1500J/KG...AND THE DAMAGING WIND THREAT
INCREASES. WILL MAINTAIN THE SEVERE MENTION IN THE HWO FOR TOMORROW
AFTERNOON AND EVENING

That's about all we can get in mid june lol

small hail and gusty winds.

I haven't seen a Moderate Risk over both DC and Baltimore since the 6/29 derecho. I think this is going to be a very wild ride.


looks like initial supercells possible.... along with hail and tornado risk..

DC area usually gets 1 big severe wx threat a year.

Between Southern Wisconsin and Southern Illinois there is going to be a 20 degree difference today. Going to be ideal conditions across NE Iowa and N. Illinois for the beginning of this outbreak. Derecho through Indiana and Ohio into Pennsylvania seems very likely. Derecho with embedded tornadoes likely, conditions are suggesting. This is looking like the real deal.

Dr. Spencer%u2019s research has been entirely supported by U.S. government agencies: NASA, NOAA, and DOE. He has never been asked by any oil company to perform any kind of service. Not even Exxon-Mobil.



Not all of his research. There is a distinction to be made. His most recent publications have been heavily debunked by climatologists, and he has signed on to the controversial "An Evangelical Declaration on Global Warming". His books have been little more than propaganda and hardly scientific. But you all ready knew this since it was discussed in Dr. Rood's blog yesterday and many other times...why keep bringing it up?

NWS STORM PREDICTION CENTER NORMAN OK
0402 AM CDT WED JUN 12 2013

...SEVERE THUNDERSTORMS EXPECTED OVER PARTS OF THE UPPER MIDWEST
INTO THE OHIO VALLEY THIS AFTERNOON AND TONIGHT...

THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
DEVELOPMENT OF WIDESPREAD DAMAGING WINDS...LARGE HAIL AND A FEW
TORNADOES OVER PARTS OF THE UPPER MIDWEST INTO THE OHIO VALLEY THIS
AFTERNOON AND TONIGHT.

THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE

EASTERN IOWA
NORTHERN AND CENTRAL ILLINOIS
MUCH OF INDIANA
WESTERN OHIO

ELSEWHERE...SEVERE STORMS ARE ALSO POSSIBLE IN SURROUNDING
AREAS...INCLUDING PARTS OF THE MIDDLE MISSISSIPPI VALLEY...SOUTHERN
GREAT LAKES...CENTRAL APPALACHIANS AND MID ATLANTIC COAST
STATES...AS WELL AS ACROSS PARTS OF THE NORTHERN ROCKIES INTO
ADJACENT HIGH PLAINS.

THE ENVIRONMENT IS BECOMING VERY MOIST AND UNSTABLE ALONG A STALLED
FRONTAL ZONE EXTENDING FROM THE MID ATLANTIC COAST WEST
NORTHWESTWARD THROUGH THE OHIO VALLEY...TO A DEVELOPING AREA OF LOW
PRESSURE ACROSS THE MIDDLE MISSOURI VALLEY. THIS LOW IS EXPECTED TO
BECOME THE FOCUS FOR INTENSE THUNDERSTORM DEVELOPMENT AS IT TRACKS
EASTWARD ACROSS EASTERN IOWA INTO NORTHERN ILLINOIS THIS
AFTERNOON...WHERE CONDITIONS LIKELY WILL BECOME CONDUCIVE TO THE
EVOLUTION OF A LARGE AND ORGANIZED CLUSTER OF STORMS. THIS ACTIVITY
IS THEN EXPECTED TO SPREAD RAPIDLY EAST SOUTHEASTWARD ACROSS
SOUTHERN PORTIONS OF THE GREAT LAKES REGION...AND SOUTHWARD TOWARD
THE LOWER OHIO VALLEY....LATE THIS AFTERNOON AND EVENING.
WIDESPREAD STRONG...POTENTIALLY DAMAGING...WIND GUSTS ARE
POSSIBLE...ALONG WITH THE RISK FOR LARGE HAIL. A FEW TORNADOES ARE
ALSO POSSIBLE...PARTICULARLY WITH EARLY STORMS ACROSS PARTS OF
EASTERN IOWA INTO NORTHERN ILLINOIS.

STATE AND LOCAL EMERGENCY MANAGERS ARE MONITORING THIS DEVELOPING
SITUATION. THOSE IN THE THREATENED AREA ARE URGED TO REVIEW SEVERE
WEATHER SAFETY RULES AND TO LISTEN TO RADIO...TELEVISION...AND NOAA
WEATHER RADIO FOR POSSIBLE WATCHES...WARNINGS...AND STATEMENTS LATER
TODAY.

Wow, SPC just came out with their projections for later today. Looking like this may be extremely dangerous. Right at the cusp of high risk. If it continues to look like this is going to pan out as the SPC sees it, I bet they go to a high risk by late morning. This could well be a billion dollar disaster day shaping up for tomorrow.
I hope not...

Anyways, does anyone think that there could be a Day 1 and Day 2 High Risk? I know that there hasn't been any high risk north of Virginia since 2000 when internet archives became available at the SPC. In fact, the only High Risk I've heard about in the northeast was in 1998 when there was a large derecho over NY/PA:

Communicating Climate Science: A Historic Look to the Future

The goal of this Chapman Conference is to bring together scholars, social scientists, and journalists to discuss both the history and recent advances in the understanding of climate science and how to communicate that science to policymakers, the media, and society. A research agenda of the conference will focus on the efficacy of scientific communication, with ideas on improved practices arising as an outcome from collaborations spawned at the conference.

This exploration will take place through: 1)

discussions covering the history of climate science and successes and failures in communicating scientific ideas to the policy makers and public;

2) an assessment of where we are with respect to current knowledge of climate science and its communication and acceptance by society; 3) a comparison with experiences in other areas producing similar difficulties between scientific knowledge dissemination, societal acceptance of that knowledge, and governance.

Live video

Wednesday addresses the challenges of ethics, morality and integrity for scientists and journalists discussing climate science using two topics to focus the discussion: Geoengineering and Adaptation/Mitigation.

Quoting SouthernIllinois:
Isn't Dr. Roy Spencer a climatologist?
He says he is, though his formal education is in weather, not climate; he holds a Ph.D. in meteorology, not climatology.

Quoting SouthernIllinois:
Isn't he the one that used to work for NASA?
Yes, a few decades ago. He's now a supporter of several anti-science ideologies (creationism, climate change denialism), and he earns a living speaking and writing on behalf of fossil fuel-funded organizations. And as has been pointed out many times, Spencer has been nearly thoroughly discredited in the science community. Not because he holds a different point of view, but because he has so often strayed completely away from logic and reason and fact as a way of supporting those views.

Having said all that: I'll be happy to look at any peer-reviewed publications that support Objectivist's contentions, even if those publications were authored by Spencer. What I won't accept are things such as graphs from his website, or excerpts of his speeches to the ExxonMobil board of directors.

Off to the pool AGAIN!! Have a great day everyone.

The tornado near Sykesville was only 25 or so miles from me, it was kinda scary when it happened.
