EXCHANGE OF AIR MASSES BETWEEN THE STRATOSPHERE AND THE TROPOSPHERE IN THE NORTHERN HEMISPHERE,
Abstract
The article presents the results of an investigation of the mechanism of exchange of air masses between the troposphere and stratosphere for given mean annual distributions of temperature in the 0-16 km layer and the distribution of atmospheric pressure on the Earth's surface by finding a wind velocity field for determining the vertical motion of air masses. It was calculated that during a year of air mass weighing 3.10 (superscript 14)T, which amounts to 5 percent of the weight of the entire atmosphere, descends from the tropopause in the 25-35 degree N zone. The weight of the 10-16 km air layer amounted to approximately 1/6 of the weight of the entire atmosphere. Thus, it is concluded that exchange of the entire air mass between the troposphere and stratosphere occurs within about 3.5 years in the 25-35 degree N zone. (Author)
