The article examines how air moves between the upper and lower atmosphere during certain weather systems in East Asia. By tracking air movements in these systems, the researchers found that air from the upper atmosphere moves down into the lower atmosphere in the center of these systems. In the outer edges, air from the lower atmosphere moves up into the upper atmosphere. Overall, more air moves from the upper atmosphere to the lower atmosphere in these systems. The strength of the weather systems affects how much air moves between the two layers. These findings show that these weather systems play a big role in quickly moving air around locally, even though they only account for a small part of the overall air movement between the two layers.
