Why is the recent high temperature weather wide, strong and long lasting? What factors are related to it?

Recently, the high temperature weather has a wide range and great intensity. The long duration is related to the sinking of subtropical high, which leads to sunny weather all the time.

According to the monitoring, the average high temperature time in China will be longer than in previous years, so people should pay attention to heatstroke prevention and cooling before the arrival of high temperature weather. Since June 13, the high temperature weather in many places in China has had a great impact and lasted for a long time. This is so strong that many people can't accept it. It has appeared in many places. The disease caused by heatstroke is called heatstroke, and the disease and high temperature events last for more than 30 days, covering a wide area and a large population in the marketing network.

These are all affected by high temperature weather. In Shandong, Henan, Hebei and other places, the electricity load has been innovated again. Tall people can't travel without air conditioning. If they stay outdoors for a long time, they will find that many people can't stand the influence of this temperature. The drought in northern Sichuan, southern Gansu and southwestern Shaanxi has continued or continued to develop, and many people in Sichuan and Zhejiang have been diagnosed with heatstroke. The global temperature is high. It can be found that the temperature in western Europe and northern Russia is more than 2℃ higher than that in the local area. Below 24℃, summer high temperature events in the northern hemisphere become more and more frequent.

Some data show that since last year, the duration and historical extreme value are not as good as this year's influence range, and the highest temperature is getting higher and higher. Especially since June, according to the analysis of the National Climate Center, the northern hemisphere is mainly affected by the big climate and the atmospheric circulation is abnormal. In June, the temperature is high. The subtropical high over the western Pacific and the Iranian high are in the strengthening stage, so they are widely influenced by the warm high, so the air is relatively dry and it is not easy to form clouds, so the solar radiation directly reaches the ground, leading to high temperature.
