At night, the rate of cooling of the mainland is higher than the rate of cooling of the sea. Consequently, the pressure on the sea is higher than the pressure on the mainland; this causes movement of wind from the sea to the land. The above two connoted situations makes the coastal regions to be windy as compared to other regions of the same latitude.
In the atmosphere, as the altitude increases by 300m, there is a reduction in temperature. Therefore, since mountains tops are located in high altitude areas, they are cooler as compared to other low altitude areas. Hot air rises up while cold air moves down a process known as orographic lift. Wind results from this process whereby hot air ascends while cool air descends. This explains why mountainous regions are windy as compared to other
