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
mountains force wind to rise as it crosses over them this cools the air causing moisture to condense in clouds and rain this produces a wet climate on the upwind side of the mountains and an arid rain shadow on the downwind sideoceans provide moisture that fuels rainstorms they also buffer the temperature of coastal regions regardless of latitudehis produces a wet climate on the upwind side of the mountains and an arid rain shadow on the downwind side oceans provide moisture that fuels rainstorms they also buffer the temperature of coastal regions regardless of latitude
