摘 要: 本文利用有限区域中尺度动力模式MM5和沙尘暴传输扩散模式相耦合的基础上,重点讨论在沙尘传输过程中,热漂移应力对沙尘粒子的作用,进行了气体-颗粒流动输送过程的并行数值模拟,计算结果与我国今年3月18日至3月21日发生的强沙尘暴实况资料进行了对比,获得了沙尘迁徙的规律。 A model has been developed on the basis of the mesoscale dynamic model (MM5) coupling with a dust-transport model with a geographic information database to simulate the process of gas-particle transport, especially well-concerning the factor of the dust thermal drift and calculating on the parallel computers. Comparisons between observations of strong dust-storm eruption in March, 20 this year and model calculations indicate that the model is able to reproduce some key features of the dust transport.
