Under the action of wind, forced convectionofair above ground and water evaporation of top soil layer will be greatly enhanced.
在风的作用下，地表上部空气的强制对流和表土层中的水分蒸发大大增强，对冻土层的热状况产生重要的影响。

The sparse distribution of the feathers, however, also allows considerable lateral air movement over the skin surface, thereby permitting further heat loss by convection.
然而，羽毛的稀疏分布也使得皮肤表面形成相当大量的侧向空气流动，从而可以通过对流进一步散热。

The influx of cold air on top of warm, moist air favours the sort of deep convection that creates powerful storms, turning moisture in the air into water on the ground very efficiently.
