When is the annual high temperature in Hubei?

The high temperature time is from June to September.

First, the annual heat in Hubei is caused by the control of high altitude in the subtropical high zone in summer; The second is the influence of topography.

1. In the Yangtze River valley at low altitude, the topography of the valley is like the bottom of a pot, surrounded by mountains, and the ground heat dissipation is difficult, which makes the temperature rise continuously; Thirdly, the rice field network is densely covered with water vapor and has high humidity, which makes it difficult for people to evaporate after sweating, greatly reducing the heat dissipation efficiency of sweating and making people feel stuffy under high temperature and high humidity.

2. Why does summer feel as hot as a stove? This song begins with the heat sensation of the human body. The main reason why people feel hot in summer is high temperature. The temperature of human skin is 32℃. If the temperature is higher than the skin temperature, people will feel hot. The higher the temperature, the longer the holding time and the more obvious the thermal sensation. Summer in Hubei lasts more than 5 months every year, with an average of 60-70 days of high temperature, and the average number of days of high temperature above 35℃ is close to 18 days. Nevertheless, the highest temperature is not the only index to measure the heat in a place. For example, the highest temperatures in Beijing and Jinan reach 42℃, which is higher than that in Hubei, but it cannot be said that these places are hotter than Hubei. This is because what really makes people feel hot is related to humidity, wind and the lowest temperature in a day, in addition to the high temperature that is maintained for a long time or often appears. Under the same high temperature weather conditions, if the wind is small, the humidity is high and the minimum temperature is high, the degree of heat that people feel will be aggravated. The high temperature period in summer is mainly from July to August, and the average temperature in Hubei is 28.6℃, while the temperatures in Chongqing and Nanjing, which are also known as the "three stoves" with Hubei, are lower than those in Hubei in July and August, which are 28.2℃ and 27.6℃ respectively. From July to August, the relative humidity in Hubei was 79%, which was the highest among inland cities in China.

If the lowest temperature in summer is above 27℃, people will feel very stuffy. The average number of days with the lowest temperature above 27℃ in July and August in Hubei is about 16 days, while in Chongqing and Nanjing it is only 8 days and 7 days. What are the reasons for the high average temperature, high humidity, low wind and high minimum temperature in summer in Hubei? Hubei is located in the middle and lower reaches of the Yangtze River. In midsummer, the upper air in the middle and lower reaches of the Yangtze River is firmly controlled by the western Pacific subtropical high. The hot sun heats the earth, and the hot earth heats the air, causing the temperature to soar. Hubei and its surrounding waters are vast, with paddy fields and ditches everywhere. Under the scorching sun, water evaporates violently, which increases the air humidity. In addition, Hubei is flat and low-lying, with low altitude, which makes it difficult to dissipate heat, making the temperature change little during the day and at night, and the minimum temperature is high. Hubei is not only hot during the day, but also unbearable at night, just like a steamer, which is also the feature of hot weather in Hubei; In addition, the urban heat island effect in Hubei is also very obvious. With the development of urbanization in Hubei, the urban heat island effect is more obvious, which also increases the heat of the city in summer.

In a word, the high temperature in summer in Hubei is closely related to atmospheric circulation, urban topography and urban heat island effect. I also want to tell you the fact that the summer heat in Hubei has been further strengthened since the 1990s. Since 1990, the average number of high temperature days in summer in Hubei is 3 days more than that in normal years, and the number of days with the lowest temperature exceeding 27℃ is 7 days more than that in normal years, which means that the number of high temperature days in our city has increased in recent years.

Second, suggestions:

1, high temperature subsidies;

2. Go out as little as possible at high temperature to prevent heatstroke;

3. Get ready for health. Warm food;
