People are nicely informed of temperature and weather pushed activities in the reduced atmosphere closest to the Earth’s surface (troposphere) in which we all stay, but are blissfully unaware of the value of the atmospheric amount earlier mentioned that (stratosphere) in driving and modulating intense weather conditions situations at the Earth’s surface.
In this collection of movies I 1st reveal the 3 substantial scale attributes of stratospheric circulation namely:
1) Stratospheric Meridional Overturning Circulation (SMOC) or Brewer-Dobson circulation that transports air from the tropical to additional-tropical stratosphere.
2) Quasi-Biennial Oscillation (QBO) of periodicity 28 months, causing descending easterly or westerly equatorial jets of air driven by tropical Kelvin and Rossby-gravity waves.
3) Stratospheric Polar Vortex circumpolar westerly jets that sort in Autumn, peak in energy in winter season, and decay in Spring can be disrupted by Unexpected Stratospheric Warming (SSW) situations.
With abrupt local climate method change, the troposphere is warming promptly, and the higher ambiance (stratosphere) is cooling, thus modifying stratospheric-tropospheric interactions in complex means.
What we do know, is that SSW is probably to take place in the next thirty day period or so, and if it does then the Stratospheric Polar Jet will break up, very similar to 3 yrs ago, and that would generate Greenland and the Canadian Arctic substantially hotter, and result in chilly outbreaks in Northern Asia and in Europe.
