What should we do about topography and meteorology?

"One mountain has four seasons, and ten miles are different." Is there really such a big difference in the weather and climate of a mountain? The climate difference between the eastern and western parts of Hengduan Mountains in China is very typical. The topography and precipitation in the west are mostly influenced by the southwest monsoon. Last year, the rainfall of Myitkyina Plain in Myanmar on the west side of the mountain range was about 1.600 mm, while the Benzilan in Jinsha River Valley on the east side of the mountain range was only 245 mm, which was equivalent to the rainfall in desert areas.

When the airflow descends over the ridge on the leeward slope, due to the heavy tax, the rainfall is extremely reduced, and the phenomenon of "wind burning" and desert landscape often appear at the foothills of the leeward slope of tall mountains.

This shows that the complex terrain will have a great impact on the weather and climate, and it will also increase the difficulty of weather forecasting. China has a vast territory and complex terrain, so it is very difficult to predict the weather.
