What climate type does Guangzhou belong to?

Guangzhou is located in the south subtropical zone, and its climate belongs to the typical maritime climate of the south subtropical monsoon. Because the back of the mountain faces the sea, the maritime climate is particularly remarkable, with warm and rainy, sufficient light and heat, small temperature difference, long summer and short frost period. Because of the same period of water and heat, it is very beneficial to the growth of crops, but the threat of natural disasters is also great. Disastrous weather such as typhoon, rainstorm, cold wave, thunder and lightning, smog and so on often bring adverse effects to industrial and agricultural production, transportation and so on.

Sufficient light and heat resources. In 2005, the annual sunshine hours in Guangzhou were 1288.5 ~ 1780.0 hours, the annual average temperature was 2 1.9 ~ 22.8℃, the annual extreme maximum temperature was 38.6 ~ 39.3℃, and the annual extreme minimum temperature was 0.0 ~ 2.3℃. This summer, high temperature and hot weather occurred in all districts (county-level cities). In winter, Conghua City and Zengcheng City have basically no cold damage except frost and freezing.

There is abundant rainfall. In that year, the total precipitation of all districts in Guangzhou was between 1384.4 ~ 2278.3mm, except Panyu District, which was less than the average of previous years by 15.0%, and other districts were 5.0% ~ 18.8% more. The total precipitation in Zengcheng is 2278.3 mm, ranking first in the city, 65438+ more than the average in previous years. Rainfall in rainy season (April to September) accounts for 80% ~ 83% of the whole year. Due to the influence of topography, there is more precipitation in mountainous areas than in plains, and more in the north than in the south. The time distribution of precipitation in that year was extremely uneven, and the precipitation in each district was obviously high from April to June. In June, affected by local heavy rain and upstream water, Zengcheng was flooded. At the same time, the rainy season coincides with strong light and high heat, forming a fairly high climatic biological potential, reaching 77865 ~ 97950 kg/ha.

The monsoon climate is prominent. The alternation of winter and summer monsoon is a remarkable feature of Guangzhou monsoon climate. The northerly wind in winter is formed by the cold air mass extending southward from the polar continent, and the weather is dry and cold; The southerly wind in summer is caused by the northward expansion of tropical ocean heating mass, and the weather is warm and humid. The conversion of summer wind direction and winter wind direction is generally in September each year, and the conversion of winter wind direction and summer monsoon is generally in April each year.
