*Monthly outlook* The stratospheric polar vortex will survive all attacks and is coming at us with a vengeance! Late December and January are expected to be milder, with only brief cold episodes!
-spread the word- The stratospheric polar vortex is coming at us with a vengeance! It was under a lot of pressure lately and was fighting for its existence. Being...
*Stratosphere warming watch UPDATE 20/Nov* A powerful warming phase now to begin in 10 days! Temperature in the stratosphere over Siberia will rise for 40°C in a few days!
-spread the word- A strong new warming phase is getting closer, and is set to begin in 10 days! The final power and the later effects are still under...
*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...
