English composition describing Yunnan's climate
Regional differences and vertical changes of climate
The latitude of Yunnan is related to altitude. From the latitude point of view, its location is only equivalent to the geographical latitude from Leizhou Peninsula to Fujian, Jiangxi, Hunan and Guizhou. However, due to the high terrain in the north and low terrain in the south, the height difference between north and south reaches 6663.6m, which greatly aggravates the temperature difference caused by latitude factors in the whole province. This combination of high latitude and high altitude, low latitude and low altitude is consistent, that is, the increase of latitude in the horizontal direction coincides with the increase of altitude in the vertical direction. Except Jinsha River Valley and Yuanjiang River Valley, the annual average temperature rises from north to south, with an average temperature of about 5 ~ 24℃ and a temperature difference of about 19℃.
Due to the influence of topography and different weather systems, the zonal distribution law of temperature in the whole province often has special circumstances, and the phenomenon of "hot in the north and cool in the south" appears. Especially in the vertical distribution, due to the mountainous territory, the river bed is constantly eroded, resulting in high mountains and deep valleys. From the valley to the top of the mountain, the climate types are different due to the height rise. Generally speaking, the temperature will drop by about 0.6℃ every time the plateau rises 100 meters. ..
