What's the difference between the weather in Xi and Guangxi?

Xi 'an Plain belongs to warm temperate zone and semi-humid continental monsoon climate, with four distinct seasons: cold, warm, dry and wet. Winter is cold, windy, foggy and less rainy and snowy; Spring is warm, dry, windy and the climate is changeable; Summer is hot and rainy, drought is prominent, and there are many thunderstorms and strong winds; Autumn is cool, the temperature drops rapidly, and the autumn rain is obvious. The annual average temperature is 13. 0℃~ 13.7℃, coldest 65438+ 10, monthly average temperature-1. 2℃~ 0.0℃, the hottest average temperature in July is 26. 3℃~ 26.6℃, and the annual extreme minimum temperature is -265433. The annual precipitation is 522. 4 ~ 7 19.5 mm, increasing from north to south. July and September are two obvious precipitation peak months. The annual sunshine hours are1646.1~ 2114.9 hours, and the dominant wind direction varies from place to place. Xi 'an is the northeast wind, Zhouzhi and Huxian are the west wind, Gaoling and Lintong are the northeast wind, Chang 'an is the southeast wind, and Lantian is the northwest wind. Meteorological disasters include drought, continuous rain, rainstorm, flood, urban waterlogging, hail, gale, dry hot wind, high temperature, lightning, dust, fog, haze, cold wave and low temperature freezing injury.

Guangxi is located in the low latitude, and the Tropic of Cancer runs through the middle of the region, belonging to the subtropical monsoon climate zone. The north and south are bounded by Hezhou-Donglan line, the north belongs to the middle subtropical monsoon climate zone, and the south belongs to the south subtropical monsoon climate zone. The extreme maximum temperature is 33.7-42.5℃, the extreme minimum temperature is -8.4-2.9℃, and the annual average temperature is between 16.5-23. 1℃. Most parts of the region have a warm climate, abundant heat, abundant rain, clear wet and dry, no obvious seasonal changes, moderate sunshine, less winter and more summer.

deposit

Guangxi is one of the regions with the richest precipitation in China. The annual precipitation in all places is above 1070 mm, and in most areas it is 1500-2000 mm, and its geographical distribution is more in the east than in the west. There are many hills and mountains and few valleys and plains; In summer, there are many windward slopes and few leeward slopes.

Due to the alternating influence of winter and summer monsoon, the seasonal variation of precipitation in Guangxi is uneven, and the dry and wet seasons are distinct. April to September is the rainy season, and its precipitation accounts for 70-85% of the annual precipitation, which is prone to floods; 10-March is a dry season, and the precipitation only accounts for 15-30% of the annual precipitation, so it is dry and rainy, which is easy to cause forest fires.

heat quantity

Guangxi has a warm climate and abundant heat. The annual average temperature is 16.0-23.0℃, the isotherm is basically banded, the temperature rises from north to south, and decreases from valley plain to hilly and mountainous areas. The annual extreme maximum temperature is 33.7-42.5℃, and the annual minimum temperature is -8.4-2.9℃.

cumulative temperature

The daily average temperature ≥ 10℃ accumulated temperature (hereinafter referred to as ≥ 10℃ accumulated temperature) indicates the available heat resources during the growth period of thermophilic crops. The accumulated temperature ≥ 10℃ in Guangxi is 5000-8000℃, which is one of the highest in China. Abundant heat resources provide favorable conditions for developing multiple cropping system according to local conditions.
