Numerical Simulation of a Dust Storm Process in Liaoning Caused by a Mongolian Cyclone
蒙古气旋引发辽宁沙尘暴天气过程的数值模拟

A dust storm event caused by a Mongolian cyclone was numerically simulated,and the dynamical,thermal features of the Mongolian cyclone and its impact on the dust storm process were analyzed.The results showed that pumping effect of the divergence at upper level was the main dynamical mechanism of the dust emission and the westerly jet from the middle Mongolia to the southern Korea offered sand source of this dust event.Vertical circulation in Mongolian cyclone and the cold advection over Liaoning were also ...
