The Mongolian Cyclone is a major meteorological driving force across southeast Asia. This cyclone is known for transporting aerosols, affecting where precipitation develops. Meteorologists are seeking ways to improve seasonal prediction of the relationship between the Mongolian cyclone and South Asia high. These features are major components of the East Asian summer monsoon (EASM) and the corresponding heavy rain events. New research suggests that analyzing these phenomena in the upper-level atmosphere will enhance the summer rainfall forecast skill in China.
