Study of Dynamic Characteristics of a Monsoon Circulation Tube
Abstract
In China with a prevailing summer monsoon, there is often on mainland China a shear line with east-to-west trend, or a quasistationary rainfall belt on the northern side of a subtropical high pressure. There is ascending movement along the rainfall belt; however, there is a subtropical high ridge line with east-to-west trend to the south of the shear line or the quasistationary front rain belt. Between the shear line and ridge line, there is a meridian circulation system with ascending movement in the north and descending movement in the south. The structure of this (more than 1000 kilometers long, in an east- to-west direction) secondary vertical circulation system is like a tube with east-to-west trend. In this article, the tubular secondary meridionally vertical circulation system (along the east-to-west trend shear line or quasistationary front cloud and rain belt) in summer on mainland China is called the monsoon circulation tube. Its characteristics reveal the configuration relationship and mutual correlation of easterly and westerly air currents, as well as subtropical high systems in the East Asia monsoon zone.
