Extreme Temperature Diary-January 28, 2018/ Batty January Weather and Extreme Global Temps

Sunday January 28th… Dear Diary. The main purpose of this ongoing post will be to track United States extreme or record temperatures related to climate change. I’ll refer to extreme temperatures as ETs (not extraterrestrials)😊. Here is today’s climate change related topic:

Batty Global January Weather

While the United States has seen a fairly typical January weather wise east of the Rockies, some portions of the planet have had some eyebrow raising and literally bat crazy conditions. Yes it got so hot in Australia during their summer that poor “flying foxes” got cooked out of the sky earlier this month:

Campbelltown, home to a large bat colony, is about 36 miles (50 kilometers) southwest of Sydney, which has a mild Mediterranean climate but can on occasion have offshore flow, which advects hot air into the area, but temperatures above 110F are very rare.

Bob Henson of Weather Underground’s Category 6 site has done a masterful job compiling some January statistics showing how squirrelly or batty the weather has been across the planet due, in my opinion, to a strong influence by carbon pollution:


From record warmth in western Europe to record flooding in France to record snow in the Alps and very cold conditions in Asia, Bob covers the wacky weather of January 2018. Here are some of the statistical highlights from the article:

1) Wednesday 1/24 was the mildest January day on record across parts of northern Europe. This includes the coastal German town of Cuxhaven, which reached 13.8°C (56.8°F). At Sønderborg, Denmark, a nationwide January heat record was set with 12.9°C (55.2°F), topping the nation’s old monthly record of 12.4°C (54.2°F) from 2005. Parts of western Europe now have a good shot at ending up with their warmest January on record. Geneva, Switzerland, has been running more than 1°C (1.8°F) above its previous record for the month as a whole, and France is likely to eclipse its monthly record set in 1936, 1988, and 2014 by as much as 0.3°C (0.5°F).

2) The Seine River in Paris reached a level of 5.71 meters (18.7 feet) at noon Saturday 1/27 and is expected to crest just below the 6.07 meters (19.9 feet) produced by the destructive floods of June 2016. Both floods have topped anything else observed in the last 36 years.

3) Massive amounts of snow fell on Davos, Switzerland, in the days leading up to the start of the 46th annual World Economic Forum. As the meeting began Tuesday morning (1/23) there was 157 cm (61.8”) of dense, compacted snow on the ground, according to the Switzerland Institute for Snow and Avalanche Research (which happens to be located in Davos). The snow depth was well short of the January record of 216 cm (85”), but it’s the first time such a snow dump has coincided with the high-profile Davos forum.

4) Strong surface high pressure and very cold air pushed into Mongolia, northern China, the Korean Peninsula, and Japan this week, leading to some uncommonly low temperatures even for places accustomed to frigid winter conditions. Readings fell as low as –53.2°C (–63.8°F) at Tsetsen-Uul, a peak in western Mongolia. Parts of extreme northeast China saw their coldest weather since 2001, including Tiluhe, which plummeted to –47.8°C (–54.0°F) on Thursday. Tokyo dipped to –4°C (25°F) on Thursday 1/25, its coldest reading in 48 years. The last time Tokyo got that cold was on Jan. 17, 1970. Several other Japanese cities had their lowest temperatures on record, albeit for datasets extending only back to the 1970s, including Otaki (–24.9°C on Thursday), Saitama (–9.8°C on Friday), and Ome (–9.3°C on Saturday 1/27).

During the last few days of this month a strong ridge is persisting over Europe, which will break down by 2/1: 

A colder than average weather pattern will persist through the end of January for most of Siberia into eastern Asia:

What’s striking to me on these charts are so many blue cold pool, stormy areas south of warmer red areas. When you see these 500 millibar anomalies in winter you get frigid air building at the surface underneath red areas feeding into the blue stormy areas. Stu Ostro of The Weather Channel and I noticed the high frequency of “high over closed low” patterns worldwide as global warming slowly increased after the turn of the century. I suspect this is why we saw heavy snow in the Alps and why cold air moved over Japan in the wake of a nor’easter type storm on 1/24, although it’s definitely hard to parse out the percent of attribution for individual winter events: http://www.news.com.au/travel/travel-updates/australians-stranded-in-japan-with-hundreds-of-flights-cancelled-due-to-extreme-snowstorm/news-story/bad3f91c8add976bd844817b49e4edc1

We’ll see what oddities occur, weather wise, in February.


Here are some ET reports from Southern California from Sunday 1/28:

Miramar reported the hottest temperature in the nation (CONUS) today / A toasty 91 degrees /
