Causes of high temperature weather in Hubei Province

Because Wu Hanyou is famous for its stoves, there are many rivers and lakes, and the water area is large. During the day, the sun is exposed to the sun, and a large amount of water vapor evaporates, which increases the air humidity. Hot air covers the whole city like a huge hood. On the one hand, the radiation speed of heat from the ground to the air slows down, and the indoor temperature remains unchanged. On the other hand, it is difficult to dissipate heat on the body surface, just like steaming sauna room, which is easy to sweat and sultry, so it is called "stove".

Wuhan is located in the middle and lower reaches of the Yangtze River. In midsummer, the upper reaches of the Yangtze River are firmly controlled by the western Pacific subtropical high. The blazing sun heated the earth, and the blazing earth heated the air, causing the temperature to rise sharply. Wuhan and its surrounding areas have vast waters, rice fields and canals. Under the scorching sun, water evaporates quickly, which increases the air humidity. In addition, Wuhan is flat and low-lying, with low altitude, difficult to dissipate heat, and the temperature difference between day and night has not changed much. The lowest temperature is very high. Wuhan is not only hot during the day, but also hot at night, like a steamer, which is also the feature of hot weather in Wuhan. In addition, Wuhan's urban heat island effect is also very obvious. With the development of urbanization in Wuhan, the urban heat island effect is more obvious, and the urban heat in summer also increases. In a word, the high temperature in Wuhan in summer is closely related to atmospheric circulation, urban topography and urban heat island effect.

Summer is hot, the diet should be light and easy to digest, and necessary water, salt, vitamins and protein should be supplemented. The weather is hot, and it is the key to replenish water in time if you want to cool down and relieve summer heat. To develop good drinking habits, drink less, and don't wait until you are thirsty. In midsummer, you should put a mat. When the ambient temperature exceeds 32 degrees Celsius, the electric fan can no longer take away the thermal sensation of the human body, so it is necessary to turn on the air conditioner to reduce the indoor temperature. Excessive fatigue is a factor that can not be ignored in inducing heatstroke, and a comfortable indoor environment can ensure a good sleep. Adequate sleep can relax the brain and body system, which is a good measure to prevent heatstroke.
