呼和浩特一次春季冰雹过程的数值模拟
Numerical Simulation of a Severe Convection Weather in Spring in Hohhot
摘要
Abstract
[ Objective ] The aim was to simulate the development process of one spring hail weather in Hohhot. [ Method ] By dint of three dimensional cumulus numerical model, and considering reai time radar echo document and ground hail data, numerical simulation was conducted to the development process of one hail in Hohhot. [ Result ] The numerical simulation suggested that in the early period of the development of hail cloud, the low layer convergence and high layer divergence were weak and the divergence layer height was low (4.5 km), Vor had weak symmetric dual structure; in the maturing period of the formation of hail cloud, the low layer convergence and high layer divergence strengthened and the divergence layer height increased obviously (9.5 km). Vor has obvious dual symmetric structure. Qg and Qt value increased rapidly and the top of Qt uplifted ( 10.5 km). The maximum updraft speed of model output Wm, divergence Div, vertical component of vortex Vor, specific water content of graupel Qg, total specific water content Qt, ground solid precipitation Rs and theoretical value, radar echo and ground observation fit well. [ Conclusion] The model had capacity to simulate strong convective cloud development process and could be developed and used continuously in the professional work of the weather modification.关键词
