Abstract

Based on conventional observation data and the ECWMF ERA-Interim 6 hourly reanalysis data with resolution 0.25°×0.25°, the frontogenesis function and the surface heat flux on thunderstorm gale on 18 May, strong wind and dust on 28 February and 9 March 2013 in Ningxia were comparative analyzed. The result shows that surface temperature was increased rapidly due to the developed thermal low or Mongolia cyclone ahead of cold fronts, then the temperature and pressure gradient across the fronts and the boundary instability enhanced by impacts of surface sensible heat flux. Further, the frontogenesis and dry convection could be easily developed, which were beneficial thermal conditions for the strong wind and sandstorms weather. The wind and sandstorms appeared in the dense gradient belt of the sensitive heat flux, the strong sandstorm appeared in the amplitude center of the sensitive heat flux. Meanwhile the important indicators of forecasting and warning for the wind and sandstorm weather in Ningxia are the intensity of the cold air, the position of high pressure ridge, the center value of the frontogenesis function, the sensitive heat flux and the obvious frontogenesis below mid and low level troposphere.

Key words
