Is there more precipitation on windward slope or leeward slope?

The windward slope is on the windward slope, and the warm and humid airflow is blocked by the terrain, so it is forced to rise and cool down, which is easy to form clouds and cause rainfall. This kind of rain is called topographic precipitation, and there is a lot of precipitation. On the leeward slope, the airflow heats up due to sinking, so it is not easy to form clouds and cause rainfall, and the precipitation is less.

There is more precipitation on windward slope and less precipitation on leeward slope; Therefore, the snow line on the windward slope is lower and the snow line on the leeward slope is higher. So windward slopes and leeward slopes are often judged according to the height of the snow line.

The windward slope is where the wind blows upward along the slope; Due to the influence of topography on climate, windward slopes and leeward slopes in mountainous areas often form different natural environments, and then form different human environments. On the windward slope, because the terrain blocks the warm and humid airflow, it is forced to rise and cool down, which is easy to cause rainfall and precipitation. On the leeward slope, the airflow heats up due to sinking, so it is not easy to form clouds and cause rainfall, and the precipitation is less.

Extended data:

In addition, if the mountain lifts the airflow excessively, the windward slope and the leeward slope even present completely different natural landscapes. For example, on both sides of the westerly belt of the Andes in southern South America, the windward slope on the west side is a temperate deciduous forest belt, and the leeward slope on the east side is a temperate desert belt.

Snow lines on windward slopes are distributed at lower altitudes, while leeward slopes are distributed at higher altitudes. Because there is more precipitation on the windward slope, it is easier to snow and the water cycle is more active. The airflow on the leeward slope sinks, heats up and dries up, and the snow is easier to melt and evaporate, while there is less precipitation and less snow.

The windward slope has superior natural conditions, dense population and towns, and developed economy. The leeward slope is the opposite. For example, the ancient poem' Rain is coming, the wind is full of buildings' generally exists only on windward slopes.

If it is an island mountain, the leeward slope is a good place to develop a bathing beach. Because the weather here is sunny and rainy, and the solar radiation is strong. Leeward slope is also the best location for saltworks. Because the downward airflow is mainly leeward slope, it is difficult to form clouds and cause rainfall, and the precipitation is very small. At the same time, the atmosphere has a weak weakening effect on solar radiation, while the solar radiation is strong, and the atmosphere is dry and evaporation is strong. Leeward coast can also be used as a safe haven for ships at sea.
