What is the definition of high temperature in meteorology? What are the causes of meteorological high temperature in China? High temperature refers to the weather, the highest temperature is 35℃, and the highest temperature in China will be 35℃ and above, or it will reach 35℃ and above for two consecutive days, reaching 38℃ and above. It is called high temperature heat wave. At present, there is no unified standard for high temperature thermal waves. How high is it? China Meteorological Science How high is the climate background provided by global warming? What about the high temperature? Under the influence of global warming, extreme high temperature events become more and more frequent. Weather system trigger

From the mouth of the weather forecast host, we often hear the explanation that "strengthening the subtropical weather will usher in high temperature weather in Jiangnan and South China", especially in summer. The subtropical high here is the subtropical high. It is a warm and high pressure system in the northern subtropical region and the main weather system that affects the summer weather in China. Due to the durability of the interior, the air is strong, the pressure gradient is small, and there is almost no wind. Therefore, in the regional control area, it is usually dominated by sunshine and high temperature weather. If the copy is strong, there will be disasters such as drought in this area.

Besides subtropical high and periphery, cold high, tropical cyclone, thermal low, weak cold front and so on. The weather system will also promote high temperature and heat waves. China Meteorological Science Urban Heat Island Effect "Adding fuel to the fire" Urban heat island effect refers to the phenomenon of temperature in the city center rather than in the suburbs. The global heat island effect has large, medium and high latitudes. The temperature difference between Berlin and its suburbs is as high as 13.3℃!
