*Stratosphere warming watch* A powerful new warming phase is building for early December. Stratospheric temperatures likely to raise over 30°C above normal, affecting the already weakened vortex!
The polar vortex is slowly but steadily losing its power. While the pressure waves are “attacking” the polar vortex, a new temperature wave is building for early December, that...
*Polar vortex UPDATE 16/NOV* The weakening of the polar vortex and the stratospheric jet stream is underway! Polar vortex collapse looks likely by the end of the year!
The weakening of the stratospheric polar vortex is well underway. The polar stratospheric jet stream is losing its momentum, as monthly ECMWF forecasts start to hint at a possible...
Stratospheric warming watch UPDATE: Polar vortex will start to weaken early next week, multiple warming phases to follow!
The stratospheric polar vortex is reaching its peak strength early next week. It will be the strongest mid-November vortex in the past 40-years. But that power will soon vanish,...
Rapid daily sea-ice growth in the Arctic began! But October 2019 still goes down in history with lowest monthly sea-ice extent on record!
October 2019 was quite a wild ride as far as Arctic sea-ice goes. It started as the 3rd lowest on record, and it finished in monthly average as record...
An unusually strong early attack on the Polar Vortex expected! Sudden Stratospheric Warming event is not excluded in the next 30-60 days
We often hear the term “polar vortex” as we head closer to winter. But this season, we will talk about it earlier than expected. We recommend you read our...
The South pole ozone hole ends its life-cycle as top 4 smallest on record, after being devastated by the record-strong Sudden Stratospheric Warming event in September!
Back in September, we witnessed a record strong Sudden Stratospheric Warming event over the South pole. These events are in most cases true game-changers for the weather across the...
Sudden Stratospheric Warming underway, mid/late January could see some serious winter weather across a large part of Europe
Two months ago, we talked about the polar vortex and its influence on the troposphere. Right now, the “Sudden Stratospheric Warming” – a large scale process – is underway...
