The windward vessel is normally the more maneuverable vessel. For this reason, rule 12 of the International Regulations for Preventing Collisions at Sea, applying to sailing vessels, stipulates that where two are sailing in similar directions in relation to the wind, the windward vessel gives way to the leeward vessel.

How does windward affect climate?

As the air moves up the windward side of a mountain, it cools, and the volume decreases. As a result, humidity increases and orographic clouds and precipitation can develop. When the air descends the leeward side, it warms and is drier because the moisture in the air was wrung out during the ascent.

Why does the windward side receive?

The windward side is subjected to prevailing winds which contains enough moisture and on striking with the surrounding mountains and hills which acts as a barrier for them, they sheds their containing moisture in that particular place. That's why the windward side receives more rainfall.
