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
Confidence votes 3.6K. Warm air holds more moisture than cold air. When the air has reached saturation point (ie. it cannot hold any more moisture), it is more likely to cause precipitation as the oversaturated air forms moisture droplets that fall as precipitation.One of the major causes of precipitation is when warm air cools rapidly (for example, when it rises after hitting a mountain front or other landmass).he higher the temperature of the air the higher the amount of  humidity you feel. Also the colder the airs temperature it can  cause precipitation such as hail, snow, and s â¦ leet rather then just  rain. Gameroo.
