Conceptual Model of Low Level Jet Rainstorm Weather and Analysis on Its Radar Echo Characteristics
摘要
Abstract
Abstract: Analysis on 12 jet rainstorms during 2002 -2010 in Guangxi indicates that jet rainstorms in Cuangxi, being in large-scale background, are resulted from combined impact of weather system and meso-microscale system. The precipitation has an obvious increasing function as low level jet is existed. It is shown in analysis on weather background that conceptual models of low level jet rainstorm weather are mainly of types as vortex jet, deep groove shear jet and subtropical high strengthened rapids. The radar echo mainly has three types as lump, belt and floe. Then through analyzing the radar echo intensity of low level jet rainstorm process, echo evolution, other product characteristics, echo source migration, rainstorm area, etc. , a short-term forecast model of low level jet rainstorm is worked out.关键词
