Freezing desert soil changes the wind-sand movement pattern.

For the nonfrozen condition, the initial values of the exponential functions between the variation in the wind erosion rate and the wind speed of desert soil show an increasing trend, and the ratios of the functions decrease steadily; that is, with increasing moisture content, the degree of skewness of each function decreases, and the degree of influence of the wind speed on the wind erosion rate decreases.

The initial value decreases as the desert soil moisture content increases, and the attenuation rate shows a decreasing trend under both nonfrozen and frozen conditions.
