The Numerical Simulation on Dust-Storm over East Asia II A Case Analysis

Abstract

Abstract: In this paper, the dust forecasting model developed in the reference 1 has been used to simulate a dust-storm case over the East Asia. The detail characters of dust-storm outbreaking, transport and deposition have been simulated. And the temporal variation of dust concentration and influencing factors of dust-storm were analyzed.

Key words: dust-storm, concentration, dry deposition

摘要： 利用文献［1］中设计的沙尘暴预报模式，详细地模拟了一个发生在东亚地区的沙尘暴天气过程，得到了沙尘暴起动、传输和沉降的具体特征。分析了粒子浓度随时间的变化，并将模拟结果与同期的实际观测比较，证明该模式对沙尘暴天气过程有较好的模拟能力。
