The French league had different values at different times: 10 000, 12 000, 13 200 and 14 400 French feet, about 3.25 km to about 4.68 km. It was used for a while together with the metric system but it is not used now. The nautical league was three nautical miles.
Why does precipitation fall mainly on the windward side of a mountain? When humid winds blow from the oceans toward mountains they must rise up to pass over the mountains. The rising warm air cools when it rises and its water vapor condenses, forming clouds rain or snow falls on the windward side of the mountain. microclimate Climate within a small area that differs significantly from the climate of the surrounding area
prevailing winds can also influence where precipitation falls. When humid winds blow from the ocean toward coastal mountains, they are forced to rise, as shown in Figure 4. The rising air cools and its water vapor condenses, forming clouds. Rain or snow falls on the windward side of the mountains the side the wind hits. By the time the air has moved over the mountains, it has lost much of its water vapor, so it is cool and dry. The land on the leeward side of the mountainsâdownwindâis in a rain shadow. Little precipitation falls there. As the air rises, it cools and
