Webimmediately below the tropopause. The lower stratosphere is taken to mean the approximately isothermal region between the tropopause and a height of approximately 30 km., above which tem perature begins to increase rapidly with height. Any theory of heat interchange in the lower stratosphere must attempt to explain these facts.
Web28 de abr. de 2024 · As most ISSRs occur in a 200 hPa thick layer below the tropopause [ 18 ], this shift is probably caused by the outwards spreading of air masses below the tropopause, which acts as a vertical boundary.
