Unprecedented June Heat on Four Continents; Wimbledon Roasts in Record Heat

By: Dr. Jeff Masters , 3:52 PM GMT on July 01, 2015

Unprecedented June heat scorched portions of four continents during the past week, and many all-time heat records are likely to fall across multiple continents this July as the peak heat of summer arrives for what has been the hottest year in recorded human history. Already on July 1, in Wimbledon, England--site of the classic Wimbledon tennis tournament--players are enduring the city's hottest day in tournament history. The mercury hit 96.3°F (35.7°C) at Kew Gardens, the nearest recording site, topping the previous record of 94.3°F (34.6°C) on June 26, 1976. London's Heathrow Airport has risen to 98.1°F (36.7°C) so far on July 1. This is not only a new all-time July record at that location, but also a July heat record for the UK, topping the previous record of 97.7°F (36.5°C) in Wisley on July 19, 2006.

We've already seen two of the planet's top ten deadliest heat waves in history over the past two months; the Pakistani government announced on Wednesday that the death toll from the brutal June heat wave in Pakistan's largest city, Karachi, had hit 1,250. According to statistics from EM-DAT, the International Disaster Database, this makes the 2015 heat wave in Pakistan the 8th deadliest in world history. The heat wave that hit India in May, claiming approximately 2,500 lives, ranks as the 5th deadliest:

Death Tolls From the 10 Deadliest Heat Waves in World History
1) Europe, 2003: 71,310
2) Russia, 2010: 55,736
3) Europe, 2006: 3,418
4) India, 1998: 2,541
5) India, 2015: 2,500
6) U.S. and Canada, 1936: 1,693
7) U.S., 1980: 1,260
8) Pakistan, 2015: 1,250
9) India, 2003: 1,210
10) India, 2002: 1,030
10) Greece and Turkey, 1987: 1,030

Extreme June heat hits four continents
Portions of four continents--Asia, Europe, North America, and South America--broke all-time June heat records during the past week, with some locations surpassing their all-time heat records for any date:

Asia In addition to the record deadly heat wave that hit Pakistan over the past few weeks, other portions of Asia also saw extreme June heat. According to weather records researcher Maximiliano Herrera, Ashkabad, the capital of Turkmenistan, set a new all-time record (for any month) with 117°F (47.2°C) on June 30, 2015, smashing the old record of 46.7°C from June 30, 1995. The national all-time heat record of June for Kazakhstan of 45.0°C came within 0.5°C of being matched, as well.

Europe
An extreme jet stream configuration is in place over Western Europe, where a strong ridge of high pressure has brought the warmest June temperatures ever recorded to the Spanish cities of Madrid (39.1° on June 28) and Toledo (40.8° on June 30).

The heat will continue over much of Western Europe the remainder of the week, when the hottest temperatures since 2006 are expected. According to Meteo France, on Wednesday, the high temperature at the official Montsouris station in Paris, France hit 103.5°F (39.7°C), the second warmest temperature ever measured there, and not far from Paris' all-time record of 104.7°F (40.4°C) set in July 1947. At least three station in France set all-time heat records:

Boulogne-sur-Mer (station opened in 1947): 35.4°C (Previous record 34.8°C on 08/112003)
Dieppe (station opened in 1949): 38.3°C (Previous record 37°C on 07/09/2006)
Melun (station opened in 1947): 39.4°C (Previous record 38.9°C on 08/122003)

North America A searing heat wave unprecedented for June scorched the Northwest U.S. and Western Canada last weekend, sending temperatures soaring to their highest June levels in recorded history for portions of Washington, Idaho, Montana, and British Columbia. Both Idaho and Washington set all-time high temperature records for the month of June on Sunday. According to wunderground's weather historian, Christopher C. Burt, the 113°F measured in Walla Walla, Washington beat that state's previous June record of 112°F, set at John Day Dam on June 18, 1961. In addition, the 111°F reading at Lewiston, Idaho was that state's hottest June temperature on record. An automated station at Pittsburg Landing, Idaho hit 116°F, but that reading will have to be verified before being considered official. A few stations had their hottest temperature for any day in recorded history on Sunday, June 28:

• Chief Joseph Dam, Washington, hit 113 degrees, topping the previous all-time record of 110 degrees most recently set on July 23, 2006. This is located near the town of Bridgeport, in north-central Washington. Records date to 1949.
• LaCrosse, Washington, tied their all-time record high of 113 degrees, set previously on Aug. 4, 1961. LaCrosse is in eastern Washington, about 40 miles west-northwest of Pullman. Records, there, date to 1931.
• Chelan, Washington, reached 110 degrees, topping their previous all-time record set just one day earlier (109 degrees). Prior to this heat wave, their all-time record was 106 degrees set most recently on July 22, 1985. Records date to 1958.
• Omak, Washington, also reached 110 degrees, topping their previous all-time record of 109 degrees set on July 8, 2001. Records date to 1931 (Maximiliano Herrera points out, though, that the station has moved 3 times, so this record may be unrepresentative of the conditions at all 3 locations.)
• Bonners Ferry, Idaho, soared to 105 degrees, eclipsing their previous all-time record of 104 degrees on July 16, 1941. Records date to 1907. 

Thanks go to TWC's Jon Erdman for compiling this list.

South America
Prior to 2015, the hottest Colombia had ever been in June was 40.8°C in June 1973 at Guaymaral. That mark was tied on June 20, 2015, at Agustin Codazzi. That mark was smashed on June 25, when both Valledupar and Urumitia hit 41.6°C. On June 27, Urumitia, Colombia beat the new June national record, with a 42.0°C reading. Three major cities, Cartagena, Santa Marta and Riohacha all set their all-time heat records in June. Argentina and Venezuela also recorded their highest June temperatures ever recorded. Thanks go to weather records researcher Maximiliano Herrera for these stats.

Talk about weather geeks. I wonder who the brave Dutchman was who stood by his instrument shelter, still taking and recording observations, while the Allies and the Germans were pounding Holland from the air and with artillery. That record high was just two weeks before "mad Tuesday" and the beginning of harsh German measures against the Dutch, leading up to the starvation Winter. Pretty amazing.

We should really find that brave Dutchman and erect a statue! LOL

The record is fairly verified, by estimates of the T850 (weather services were functioning pretty well during the war, letting up more balloons than we do nowadays maybe) of 22-23° C (a bit over today's) and surrounding stations (including some German, btw just over the border today 38.5° C - I'm using official stations only). Maastricht, where today's record was set, did 38.0° C on that 1944 day. This city also holds second place though from a different station location, 38.4° C on the 27th of June 1947.
Note: the forties were a remarkable decade. They include three of the four coldest winters in Holland since 1900: 1947, 1942, 1940 in that order, only surpassed by 1963). And the second coldest winter of past century, 1947, was followed by the hottest summer 'ever' (since at least 1706), this summer still is #1. Some blocked year, that.

They should just leave it at the number of confirmed on the ground tornadoes; that covers both rural and urban areas. If you used another ruler such as number of buildings destroyed, that could also be misleading if you consider a populated area strike vs. a rural area strike, One tornado in a populated area might destroy/damage 50 buildings with no deaths and another one in a rural area might hit 10 homes and kill 5 people. But the overall numbers speak for themselves.
As I wrote earlier, property damage is not a good ruler. I'm thinking in terms of something equivalent to ACE for TCs as a measure for tornadoes - which, owing to the nature of the beast and the dependence on human reports, may not be possible.

Yes. Well, I think 38.2� C is going to be the value for today. Third highest ever measured in the country and by far the most reliable measurement (both previous 38 's were in June 1947 and August 1944).
We also had the highest minimum temps 'ever' last night.

We're going to try a second attack on the national all-time record on Saturday :)

(by the way, official record of Warnsveld '44 is 38.6� - there might be a double Fahrenheit conversion error there, dr. Masters :) ).

I find it ironic that the area where the block appears happens to correspond with the cold pool anomaly off of Greenland.................Just sayin.

The North Atlantic between Newfoundland and Ireland is practically the only region of the world that has defied global warming and even cooled. Last winter there even was the coldest on record – while globally it was the hottest on record. Our recent study (Rahmstorf et al. 2015) attributes this to a weakening of the Gulf Stream System, which is apparently unique in the last thousand years.

No surprise:



We continue to foresee a below-average 2015 Atlantic hurricane season. A moderate to 
strong El Niño is underway, and the tropical Atlantic remains cooler than normal. We 
are still calling for a below-average probability of United States and Caribbean major 
hurricane landfall. A more detailed forecast will be released on 3 August. 
(as of 1 July 2015)
All new June data support our 1 June forecast and add more confidence to our 
anticipation of a strongly suppressed season. Negative factors for hurricane activity that 
persisted through June include: 1) continued emergence of a strong El Niño event, 2) 
continued unfavorable Atlantic basin sea surface temperature (SST) and sea level 
pressure (SLP) conditions, and 3) continued unfavorable horizontal and vertical wind 
shear conditions throughout the Atlantic.

Violent hailstorms in Yorkshire and in County Durham damaged windows, cars and roofs. Residents said it was "unbelievable". ...
In Swaledale, Yorkshire, Linda Scott described the storm as "carnage". Her home had two windows broken, tiles came off the roof and the satellite dish snapped in half. ...

Why on earth do they mention deaths from tornadoes as though it's some kind of ruler to measure severe weather? Even numbers of tornado sightings - which is what SPC collects - can be misleading.

Not arguing El Nino does not affect severe. Of course it does. Let's hope someone finds meaningful "rulers" for severe - if that's even possible.

You know, this never ending critique of scientific data because you disagree with the way it is constructed is both a poor critique and extremely tiresome. We get it, you don't like how data is calculated, uncertainty exists, and because of that, you make the false logical leap that it is impossible to know anything with any degree of accuracy.

Here is blurb on this past tornado season and the lower activity linkage to the El Nino issue. Just noting that this was the first time in recent history when we had a strengthening El Nino in the Spring (as opposed to a phase shift) and that the most active spring tornado seasons for the US (per research) have occurred during a waning El Nino transition (either to a neutral phase or the most active period entering a La Nina period for the summer). Too early to know at this stage whether the current El Nino will persist into April-May 2016 or transition away.

http://news.sciencemag.org/climate/2015/07/how-el -ni-o-saved-you-tornado-spring


Earlier this year, scientists predicted that 2015's tornado season would likely be fairly tame, because El Niño—a global weather phenomenon marked by unusually warm surface waters in the eastern tropical Pacific—prevails and suppresses twister development across much of the nation. Now, with the peak tornado months of April, May, and June behind us, those predictions seem to have come true. For the first half of 2015, the Storm Prediction Center in Norman, Oklahoma, reports a preliminary count of817 tornadoes striking the United States, 19% below the 10-year average of 1006 tornadoes; the tornado shown here struck Halstead, Kansas, in May. Moreover, through 28 June, tornadoes killed only 10 people, far fewer than the 70 people killed during the first half of 2012, the 45 people killed during the first half of 2013, and the 37 people killed during the first half of 2014. The big question for next spring is whether El Niño persists or instead yields to its often more deadly opposite: La Niña ruled much of 2011, the year when a fierce tornado devastated Joplin, Missouri, and killed 158 people.

"The region found to have the most dramatic erosion was the northeastern part of the National Petroleum Reserve-Alaska -- from Cape Halkett to Drew Point -- where soil has been eaten away at an average rate of 6.3 meters (20.7 feet) a year, according to the report."
...
"A team led by University of Colorado researchers, for example, has focused on Beaufort Sea bluffs where certain spots have eroded at rates of up to 30 meters (98 feet) a year. Their work included time-lapse photography that shows large chunks of the bluff at Drew Point disappearing over a few weeks in July 2008." - Alaska Daily News.

Full Article: north-slope-coastal-erosion-rates

What makes it really astounding is that it all happens during the melt season, which is getting longer due to global warming. The article is pretty scary overall - especially since the Gulf Coast in the L48 (Louisiana and Mississippi) have some high and in some cases higher erosion rates too.

Conventional thinking may be, who cares -- However, there are communities there that will have to be relocated (and one already has been once) AND in terms of a national significance, it affects the oil fields. BP and ConocoPhillips both have facilities that are now in danger.

This is a great article, Dakster, with some really good links. Thanks for posting this.

Good Morning. The current MJO phase is really taking care of business in the West-Pac:

For being around since 2008, you seem to have missed reading the many blog entries here that discussed the cold, snowy NE winter and spring. Anyway, I suppose to some it's noteworthy that the Northeast has been below average the past six months--though, frankly, the little area of light blue (below average) on the map below isn't nearly as impressive as the much larger area of light orange (above average) on the map, or the much larger area of orange (much above average), or the much larger area of red (record warmest).



Or, taking a global view:

Was the usual revisionist crap and got deleted as such, hail.

I flagged it due to the sheer disrespect shown regarding Dr. Masters. I honestly don't really care if someone espouses an opinion regarding AGW/CC that is at odds with the science - I don't flag these. But posts that allege dishonesty/lack of integrity/deceit/a mysterious agenda on the part of Dr. Masters or the scientific community in general- these I flag.

It's one thing to not understand or accept the science. But unsubstantiated, wild allegations are a whole different level of 'bad'.

Noting what Barb had to say and the heat maps for Europe.321. barbamz

This kind of heat over central Europe will be also causing a lot of snow and ice melt over the Alps region.

The below average temps for the US northeast are unlikely to be causing any problems other than minor discomfort.
The above average temps elsewhere will be causing everything from discomfort to deaths from the heat.

What is "Self Organizing Map Cluster Analysis?"

That's exactly where I got tripped up. I did try wiki, as Chris has suggested in his post, and frankly, it didn't help me much. BUT, wiki gave a brief mention as to where/how SOM is used, and included a link to this article:

A Review of Self-Organizing Map Applications in Meteorology and Oceanography

While any math I may have learned to help understand this has long been forgotten (due to lack of use), this article really is a good summary of how SOM is used in meteorology & oceanography, and includes a brief explanation of SOM, without the overwhelming math.

Quoting 311. ChrisHamburg:



Good morning from Europe, here is a wikipedia link for an introduction and short explanation of this method to create a 2 dimensional map for higher dimensional observation. Wikipedia is for some scientific questions a really good introduction, really helpful in mathematics for me. I'm a book person and reading scientific books with the mathematics would be impossible for me without this site. I have my sight on this book, because it explains multifractal cascades statistical analysis. Stumbled on this method in a paper and was intrigued. Yes I'm a nerd, but even if I understand only 10-20 % of it, I really love reading such stuff.

Good morning, Chris. Wow, that book is not cheap. And it's only available it seems in an e version, so no possibilities of a less expensive used copy? The book is not my particular cup of tea, but nerds come in many varieties; I've got my own quirky interests :-)

...All this talk of heat and not a word re the Northern NE US having one of the coldest six months in history.
