The Telegraph - 1/19/13, Cole Moreton

Meteorologists have warned that the bitterly cold weather sweeping Britain may last for weeks as a disturbance in the upper atmosphere keeps temperatures low.

Snow brings its usual struggles... but at least the forecast was right

As the hardest hit areas enjoy a respite from snow today, and ice becomes the main danger, experts say this wintry blast is the result of a phenomenon called sudden stratospheric warming — and they warn that its effects could last for up to a month more.

“This is a major event in the stratosphere, and it’s driving the cold weather,” said Adam Scaife at the Met Office.

CME IMPACT: A coronal mass ejection hit Earth's magnetic field on Jan. 19th at approximately 17:15 UT. The impact appears to be weak. Nevertheless, high-latitude sky watchers should be alert for auroras. Aurora alerts: text, voice.

The Solar and Heliospheric Observatory photographed the CME emerging from the sun's southeastern limb on Jan. 16th at 22:06 UT:

 

 

Although the cloud appears to be engulfing Mercury, it is not. Mercury is currently on the farside of the sun while the CME is on the nearside, heading more or less in our direction. The overlap is visual, not physical.

I didn't want the week to end without documenting the rapidly deepening low-pressure system east of Japan on Monday and Tuesday. The mid-latitude cyclone's minimum barometric pressure fell from 965 mb at 12Z on January 14 (surface analysis from the Ocean Prediction Center) to 932 mb at 06Z on January 15 (OPC surface analysis), a drop of 33 mb in just 18 hours. Explosive cyclogenesis, indeed (note the reference to hurricane-force winds on the 06Z surface analysis).

At 00Z on January 16, OPC's analysis (above; larger image) of the significant wave height, the average height of the highest one-third of the waves, indicated heights of 20 meters or more (well over 60 feet). Dramamine, any one?

An unusual event playing out high in the atmosphere above the Arctic Circle is setting the stage for what could be weeks upon weeks of frigid cold across wide swaths of the U.S., having already helped to bring cold and snowy weather to parts of Europe.

This phenomenon, known as a “sudden stratospheric warming event,” started on Jan. 6, but is something that is just beginning to have an effect on weather patterns across North America and Europe.

"Winter Storm Iago is exiting stage right," says Winter Weather Expert Tom Niziol. Iago moved off off the coast of Cape Cod and into the Atlantic on Friday, but not before dumping snow and ice on a huge swath of the U.S. It left a dangerous morning commute in its wake. 

"Even after Iago was gone, temperatures dropping below freezing caused concerns about black ice and lingering snow on the ground from Mississippi to Virginia," says weather.com Sr. meteorologist Jon Erdman.
