行星边界层变形场与大暴雨落区
The Deformation Field in the Planetary Boundary Layer and Heavy Rainfall
-
摘要: 本文通过对1979—1981年梅雨期行星边界层变形场的分析，说明行星边界层上部变形场与大暴雨密切相关。利用它可以判断低气压系统的移动和发展，对未来12—24小时大暴雨落区预报有一定指示意义。Abstract: In this paper, statistical analyst is was made on heavy rainfalls occurring in Hubei Province and the deformation field in the planetary boundary layer during Meiyu period of 1979—1981. It is found that heavy rainstorms are closely related to deformation field in the planetary boundary layer. Analyzing the deformation field in the planetary boundary layer gives a criterion for the movement and development of low pressure systems as well as an indication for the forecasting of heavy rain area in 12—24 hours
