December to February period covers the 3 coldest months of the year, which is why this is designated as the meteorological Winter period. Before winter, a lot has been said about the influence of the cold ENSO phase (La Nina) on the weather development, especially in our December winter forecast overview. But in January 2021, new weather dynamics will enter the scene. Sudden Stratospheric Warming (SSW) is one of the most powerful weather events that can occur in winter. Most often in late December and January. We produced a high-resolution video that shows the high amplitude stratospheric warming in the first week of January 2021 weather development. In the video, we have the temperatures at the 10mb level (~30km altitude). .... .... .... ---continued at link--- |
