Climatic characteristics of Guangzhou

Guangzhou is located at low latitude, and the surface receives a lot of solar radiation. At the same time, influenced by the monsoon, the ocean warm current forms a climate of high temperature, high humidity and rainy in summer. In winter, the cold wind in the northern mainland forms a climate of low temperature, dryness and little rain.

1. Temperature: the annual average temperature is 2 1.4-2 1.9 degrees, 2 1.4 degrees in the north, 2 1.7 degrees in the middle and 2 1.9 degrees in the south. The hottest July-August, the average temperature is 28.0-28.7 degrees, and the absolute maximum temperature is 38.7 degrees; The coldest is 65438+ 10 month (February in some years), the average temperature is 12.4- 13.5 degrees, and the absolute minimum temperature is -2.6 degrees. The average temperature rises gradually from1-July every year. 165438+1Frost may occur from late October to mid-February.

2. Rainfall: The average annual rainfall is 65,438+0,623.6-65,438+0,899.8mm, which is more in the north than in the south. The annual rainfall increases gradually from 65438+ 10, and increases sharply in April, with the maximum rainfall in May-June, mainly in the flood season from April to September. 65438+ 10 is dry in rainy season from March to the following year, with frontal rain in the first flood season from April to June, tropical cyclone rain in the second flood season from July to September, followed by convective rain (hot thunderstorm).

Three. Illumination: (1) The annual average solar radiation value is 4367.2-4597.3 MJ/m2, which is distributed in the south and high in the north. In a year, solar radiation is the lowest in February and the highest in July. (2) Sunshine Hours When the average sunshine hours of the year is 1 820- 1 960, the annual sunshine percentage is 4 1%-44%, which is more in the south and less in the north. Seasonally, summer is the most, followed by autumn, winter again, and spring is the least.

Fourth, the wind: affected by the monsoon, the winter in South China (65438+ 10) is controlled by cold high pressure, with northerly winds and northeast winds; In spring (April), the wind direction is messy, but there are more southeast winds; In summer (July), influenced by subtropical high and South China Sea low, southerly winds predominate; In autumn (65438+ 10), the summer monsoon turns into winter monsoon, with northerly winds as the main wind. In terms of average wind speed, the wind speed is higher in winter and spring and lower in summer. However, tropical cyclones often attack in summer, and the wind speed can increase sharply to a gale of magnitude 8 or above.
