Greenland temperatures surge up to 50 degrees above normal, setting records

[essentialsaltes]

This latest warm spell in Greenland pushed the temperature in its capital, Nuuk, up to 59.4 degrees (15.2 Celsius) on Sunday, the warmest on record for March or April, according to climate expert Maximiliano Herrera. The average March high in Nuuk, which sits on the southwestern coast of the island, is about 23 degrees (minus-5 Celsius).

The warmth is related to a phenomenon that meteorologists call the “Greenland block,” a stagnant zone of high pressure that causes the air to sink and warm beneath it. The block may have developed in response to a sudden warming at high levels of the atmosphere in February. The “sudden stratospheric warming” disrupted the polar vortex, a pool of frigid air that kept Greenland chilly through the core winter months.

With the current Greenland block drifting southwest, the highest temperatures compared with normal are shifting out of Greenland and into Nunavut, Quebec, Newfoundland and Labrador in Canada. Record-high temperatures are still occurring from northern Greenland into Quebec.

True enough about the block. Not new. Affects most of North America as the jet stream gets rearranged. Many records get broken by a few degrees that interestingly were set over a hundred and twenty five years ago so it would appear what goes around comes around. But after three years La Nina has just broken free and El Nino will be fully back by summer. Guess the currents were clogged up by plastic.

The warm and cool bubbles have kept coastal North America and the US especially weather active this winter and spring looks to be ramping up also. Canada for the most part normal.
