Topographic precipitation is generally formed or in what mountainous area?

The phenomenon of precipitation caused by the forced uplift of airflow along the hillside is called topographic precipitation. Topographic precipitation often occurs on windward slopes. When warm and humid air flows over the mountains, if the atmosphere is unstable, it can also produce convection and form cumulus clouds; If the upward movement of airflow on the mountain is combined with the thermal convection in front of the hillside, cumulonimbus will develop into cumulonimbus and form convective precipitation. In the process of frontal movement, if the forward direction is blocked by mountains, the frontal movement speed will slow down, the precipitation area will expand, the precipitation intensity will increase and the precipitation time will be prolonged, resulting in continuous rainy weather, which can last for more than 10 ~ 15 days.

In the world, the wettest place often appears on the windward slope of the mountain, which is called rain slope; The leeward slope has less precipitation and becomes a dry slope or "rain shadow" area. For example, the mountain slope in Scandinavia, Norway is windward, and the precipitation 1000 ~ 2000mm, while the leeward slope is only 300mm. For another example, the northern, eastern and southern sides of the mountains in Taiwan Province Province, China are windward, with a lot of precipitation, with an annual rainfall of more than 2,000 mm, and the burning fire in Taipei reaches 8,408 mm, which is the place with the most precipitation in China. As soon as it reaches the west, it becomes a rain shadow area, and the precipitation decreases to about1000 mm. The annual precipitation on the windward slope of Kauai Island in the Hawaiian Islands is 12040 mm, which is the place with the largest annual rainfall in the world. The annual precipitation in Kilapanchi, India is 1 14 18mm, which is also because it is located at the southern foot of the Himalayas. These rain slopes are generally topographic precipitation.
