Spitsbergen as a Heating Spot
If one asks whether the heating-up spot is to be found at Spitsbergen, we would answer: yes. The information supplied sustain this affirmative answer. Nothing demonstrates this better than the data record taken at Spitsbergen since 1912. If one reviews the January/February temperature difference between the winters of 1913/14 and of 1919/20 (ca. + 15oC), or from the winters of 1916-1917 to the winters of 1919-1920 (ca. + 22oC), the results are not only extraordinary, but they reveal that the “shift” took place in 1918, respectively in the winter of 1918/19 (Hesselberg, 1956). This is emphasized by the comparison between the data recorded from 1912, until WWI ended in November 1918 (ca. – 4.3oC), and thereafter (ca. +3.8oC), including the winter of 1925/26.
In the summer of 1918 the seawater temperatures had already reached unusual values: +7oC to +8oC at the West coast of Spitsbergen (Weikmann, 1942). During the winter of 1918/19 the temperatures varied considerably. There were long periods in November and December 1918 with temperatures close to zero degrees, 4 days with temperatures above zero in November and 7 days in December. In January 1919, the temperatures did not reach -5oC for 14 days, and five days were frost-free. The annual mean (1912-1926) with minus 7.7oC suddenly jumped to an annual average of minus 5.4oC in 1919, representing a plus of 2.3 degree. The corresponding figures provide for January a difference + 8.6oC, which indicates that the sea was able to transfer a lot of heat into the air. However, during February-April 1919, the temperatures were well below the average (ca. -6oC), with a large ice-cover far out into the sea. But that did not affect the significant warming that had started a few months earlier.

U.S. Cold Snap New Year Day 2018
Off the coast of Norway, from 20th to 21st December 1939 a drop in air pressure of 54,5 mb (see Fig. below) occurred within 24 hours, which caused up to 12 Bft wind. Was naval war activities related?
Few days later temperature fell dramatically from all over in Northern Europe;
First January week 2018: North America’s East Coast is shivering in a record-breaking freeze in the wake of a deadly “bomb cyclone” that dumped snow as far south as Florida.
In parts of US and Canada, temperatures were forecast to fall below -20F (-29C), on Friday night (4/5 Jan 2018).
A “bomb cyclone” or “weather bomb” is an unofficial term when the central pressure of a low pressure system falls by 24 millibars in 24 hours

Wind chill and freeze warnings stretched from New England to Ohio and Pennsylvania. In some of these places, exposed skin could freeze within 30 minutes,
In New Hampshire, the ambient air temperature on Mount Washington plunged to -36 F (minus 38C), two degrees short of a record low for Jan. 6.
The East Coast’s first snowstorm of 2018 was energized by a rapid drop in barometric pressure that some weather forecasters called a bombogenesis, or a “bomb cyclone.” The phenomenon gave rise to gusts of more than 70 mph (113 km/h) and produced snowfall totals of 22 inches (56 cm) in parts of Maine and 17 inches (43 cm) in parts of Massachusetts, the NWS said.
Jan 8, 2018 – Extract -: The blast of arctic air that has engulfed the US east coast has broken temperature records in several cities.
The National Weather Service said the temperature in Worcester, Massachusetts, fell to -22c on Sunday, (01/07/18) breaking a record of minus -19c set in 1942.
In Providence, Rhode Island, temperatures of -19c set a new record low.
And in Hartford, Connecticut, the temperature dropped to -23c, smashing the previous record of -17c.
Boston tied a low-temperature record set more than a century ago in 1896 of -18c.
Many residents in north-eastern states endured jaw-clenching temperatures and brutal wind chills on Saturday as cleanup continued from the storm that dropped as much as 46 centimetres of snow in some places on Thursday.
