Guangdong Province belongs to the East Asian monsoon region, which is characterized by subtropical climate, subtropical climate and tropical climate from north to south. It is one of the regions with the richest light, heat and water resources in China. From north to south, the annual average sunshine hours increased from less than 1500 hours to more than 2,300 hours, the annual total solar radiation was between 4,200 and 5,400 mj/m2, and the annual average temperature was about 19℃ ~ 24℃. The average sunshine hours in the province 1745.8 hours, and the annual average temperature is 22.3℃. The average temperature in June 5438+ 10 is about 16℃ ~ 19℃, and the average temperature in July is about 28℃ ~ 29℃.

Guangdong is rich in precipitation, with the annual average precipitation of 1300 ~ 2500mm, and the average of the whole province is 1777mm. The spatial distribution of rainfall is basically high in the south and low in the north. Affected by topography, there are three rainy centers on the windward slope of the mountain, which are Enping, Haifeng and Qingyuan, which are beneficial to the formation of precipitation due to water vapor uplift, with an average annual precipitation of more than 2200 mm.

The average annual precipitation in Luoding Basin and Xingmei Basin on leeward slope, as well as the coastal Leizhou Peninsula and Chaoshan Plain with little rain is less than 1400 mm ... The precipitation is unevenly distributed during the year, and the precipitation in flood season from April to September accounts for more than 80% of the whole year. The interannual variation is also great, and the precipitation in rainy years is more than twice that in dry years.

Floods and droughts often occur, and the impact of typhoons is more frequent. Low temperature and rainy weather in spring, cold dew wind in autumn and cold wave frost from late autumn to early spring are also frequent disastrous weather in Guangdong.

Extended data

Guangdong is rich in water resources, with annual precipitation of 3 194 billion cubic meters, river runoff of181900 million cubic meters, and passenger flow of Xijiang and Hanjiang neighboring provinces of 233 billion cubic meters. In addition, there are 6 billion cubic meters of deep groundwater, and the per capita exploitable water resources reach 4,735 cubic meters.

The main water systems in Guangdong are Xijiang, Dongjiang, Beijiang, Delta and Hanjiang in the Pearl River, followed by Rongjiang, Lianjiang, Luohe and Huanggang in eastern Guangdong, and Yang Mo, Jianjiang, Jiuzhou and Nandujiang in western Guangdong, which enter the sea alone. The spatial and temporal distribution of water resources in Guangdong is uneven. The navigation capacity of the Pearl River is second only to that of the Yangtze River, ranking second in China, second in national water system and fourth in length and basin area.
