The Activities of Equatorial Anticyclones of the Western Pacific and the South China Sea and Their Effects on the Tracks of Typhoon Movement
Abstract
This paper carries out a preliminary investigation and analysis of the activities of equatorial anticyclones over the western Pacific and South China Sea. They occur on average 8 times a year and are mostly concentrated during the months of June-September. An equatorial anticyclone is a tropical weather system of meteorological magnitude of 1,000 - 2,000 km. It can continue on for a few days. It is a kind of a warm and high pressure system, and is often related to a fair weather system. The equatorial anticyclone clearly has an effect on the development of the typhoon genesis and the track of its movement. once a deep, thick and strong equatorial anticyclone appears to the south of a typhoon, the typhoon often seems to search for its path. However, the actual track of the typhoon is determined by the high pressure cooperative activities of the equatorial anticyclone and subtropics. This paper also presents several typhoon tracks for analyses.
