The temperature in many places has broken records. Why is it so hot this year?

It is a natural phenomenon to have a large range of high temperature weather in summer, but the intensity and duration of this year's high temperature weather are extreme, such as the extreme high temperature weather in Sichuan and Gansu. Forecasters said that the high temperature weather was wide in scope, strong in intensity and long in duration. Affected by the spread of subtropical high from west to north, the influence range of high temperature weather will be further expanded in the future. The hot weather will continue in most parts of the south.

According to experts, the extreme high temperature in the south is due to the strong subtropical high in the south, which is entrenched in the middle and lower reaches of the Yangtze River. Under the control of this huge heating mass, the airflow sinks, the temperature is high, and there is little rain; This weather situation also makes the typhoon path southward, which is not conducive to alleviating the high temperature. Large-scale high temperature weather in the south? The culprit? It is the western Pacific subtropical high (referred to as subtropical high for short). Shanghai, southern Jiangsu and northern Zhejiang, where severe high temperatures occurred this time, are all near the center of this weather system. In addition, the subtropical high control area is prone to high temperature weather to some extent because the air will heat up during the sinking process.

The current climate is very abnormal. The temperature in the whole country is generally high this year, much higher than the same period last year. This is one of the most intuitive reasons for the gradual warming of the earth. In fact, it will not have much impact on our life at present, but if the climate continues to deteriorate, the iceberg will slowly melt. The sea level rise has the greatest impact on Japan at first, because the average sea level in Japan is relatively low.

In summer, the temperature is high and the sunshine is strong. We try to avoid working outdoors or exercising in the scorching sun, especially in the hot afternoon, for the elderly and sick children. You must work outdoors and take good sun protection measures. Simple: wear light-colored or light-colored clothes, a hat or an umbrella. Replenish water, especially boiled water and salt, and some commonly used drugs, such as cool oil and cool oil. Because of the high temperature intensity and long duration, it has adverse effects on power supply, domestic water, tourism and agricultural production. Relevant departments should pay attention to meteorological early warning information, do a good job in energy and water resources scheduling, and prevent urban forest fires.
