*Winter 2019/2020* FINAL November model forecast for the upcoming winter! Summary: Polar vortex collapse might be the make or break factor for many this winter!
-spread the word- November model calculations are done, and they are usually regarded as the final forecast for winter. December is already a winter month, so November forecasts will...
*Stratosphere warming watch UPDATE 18/Nov* A powerful new warming phase is coming in early December! Calculations now start showing a Sudden Stratospheric Warming event! 3D animation added!
-spread the word- New model calculations are done, and they still show the powerful new warming phase coming in early December. Each new model calculation increases the likelihood of...
*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!
-spread the word- 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...
*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!
-spread the word- 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...
Stratospheric warming watch UPDATE: Polar vortex will start to weaken early next week, multiple warming phases to follow!
-spread the word- 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...
An unusually strong early attack on the Polar Vortex expected! Sudden Stratospheric Warming event is not excluded in the next 30-60 days
-spread the word- 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...
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!
-spread the word- 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...
Polar vortex: What exactly is it, and why you should care about it?
-spread the word- Every winter, we often hear the term “polar vortex” in various media. Some call it a stratospheric hurricane, some call every winter storm a polar vortex...
