Explain what windward slopes and leeward slopes are.

The so-called windward slope means that the direction of the wind is towards the mountain. The windward slope is cooled due to the terrain blocking the warm and humid airflow, and Yi Yun is prone to rain and has more precipitation. Leeward slope is popular in downward flow, but it is difficult to cloud and cause rain, and the precipitation is less.

There are also differences in precipitation at different altitudes on windward slopes. There is less precipitation in the foothills and hilltops. Due to insufficient airflow uplift at the foot of the mountain, the rainfall caused by cloud formation is less, the air humidity at the top of the mountain is greatly reduced, the cloud rain is less, the precipitation in the mountain is the most, and the precipitation at the top of the mountain is less.

The diurnal temperature range of windward slope and annual range are smaller than leeward slope. Due to the rainy weather on the windward slope, the atmosphere has a strong weakening effect on solar radiation during the day, and the temperature will not rise excessively. At night, the atmosphere has a strong heat preservation effect on the ground, and the temperature will not drop excessively. On leeward slopes, the situation is just the opposite.
