Hot ҈ ҈ ҈ ҈ ҈ ҈ ҈!How long does it last for Henan high temperature?

Yesterday 40 ° C, 40 ° C today, continuous high temperature days, entering the climax stage. So, how strong is Henan's longest and strongest high temperature process since the summer? What is the culprit behind it? When is it expected to end?

On the afternoon of June 17, the Henan Meteorological Bureau held a press conference on this round of high temperature weather. Before June 22, Henan still focused on sunny heat and high temperature weather. The highest temperature in most counties and cities was above 37 ° C. From the night of the 22nd to the 24th, the province will have a process of precipitation. This round of high temperature weather will be announced.

In the past two days, the average maximum surface temperature of the province exceeded 60 ° C, and the temperature of multiple places broke through 40 ° C continued

According to the introduction, the high -temperature weather in this round has the characteristics of a wide range, long duration, and strong intensity. From June 13, high temperature weather from 37 ° C to 39 ° C in central and southwestern Henan began. On the 15th, the high temperature area expanded rapidly between Huanghuai in the province, and the intensity increased significantly.

On June 15-16, the average maximum temperature in the province exceeded 37 ° C for two consecutive days, and the average maximum surface temperature exceeded 60 ° C. Among them, the average maximum temperature in the province was as high as 39.6 ° C, and the average highest ground temperature reached 63.5 ° C.

On June 16, the maximum temperature of 59 stations in the 120 national meteorological stations in the province exceeded 40 ° C. Linzhou, Wuyang, Luohe, Xiping, Lintong, Anyang, Xuchang, Suiping, Shenqiu, Jiaozuo, Wenxian 11 The maximum temperature of the station daily exceeds 41 ° C; the Linzhou Meteorological Station reached 42.0 ° C, the highest in the province, and the highest at Zhengzhou Station was 40.4 ° C.

The highest temperature of the 92 stations in the province exceeds 60 ° C, and the highest surface temperature of 8 stations exceeds 70 ° C; the highest surface temperature of Xixia Station is 74.1 ° C, which is the highest in the province. Dance Steel and Mall Breakthrough Breakthrough in June, the highest temperature extreme value of the same period since the establishment of the station.

On June 17, a total of 10 stations in the province had a total of 40 ° C at the highest temperature, the highest temperature of 72 stations was 38-40 ° C, the maximum temperature of 35 stations was 35-38 ° C, and the maximum temperature was 40.6 ° C in Wuyang County, Luohe City. The highest temperature at Zhengzhou Station is 40.3 ℃ (15 o'clock).

On the 17th, the surface temperature monitoring showed that most of the surface temperatures in our province were above 50 ° C, and some counties and cities were above 60 ° C, and Qixian County was up to 67.6 ° C. The highest surface temperature of Zhengzhou Station is 64.3 ℃.

The cause is controlled by the low pressure of the ground, and the short wave of the sun during the day is greatly affected

So, what is the cause of this exceptional high temperature? Su Aifang, a senior engineer of the Henan Meteorological Observatory and the national chief forecaster, analyzed that the high -temperature weather was mainly affected by the low pressure of the ground, and most of the Henan was mainly sunny and hot and rainy weather. Coupled with the influence of short waves of sun wave during the day, the weather is dry, which is conducive to the gradual increase of ground temperature.

At the same time, Henan was controlled by high -altitude and high -pressure spine, which prevailed in sinking airflow, forming a certain sinking temperature increase effect, and caused high temperature weather under the comprehensive effect of radiation to increase and sink and temperature.

Since June this year, the average temperature in the province is 27.9 ° C, which is 2.7 ° C higher than the same period of the year, the third high value since 1961; the average maximum temperature is 34.7 ° C, which is 3.4 ° C higher than the same period. Four high value.

Xixia, Qixian, Luoning, Yanshi, Ling, Zhumadian, Xinmi and other 7 stations and other 7 stations have made the extreme value of the same period since the establishment of the station in June.

The trend is at least until next Wednesday, and a rainfall temporarily interrupted the high temperature process

So, when will this round of high temperature day end? According to the latest analysis and prediction, before June 22, Henan still mainly focuses on sunny heat and high temperature weather. The maximum temperature in most counties and cities is above 37 ° C, and some counties and cities in the north are 39-41 ° C.

On the 23rd, due to the significant northern jump of the subtropical high pressure, from the night of the 22nd to the 24th, the province will have a process of precipitation. This round will continue to end high temperature weather.

Due to the long duration and intensity of the high temperature weather process, the meteorological department reminds that it is necessary to pay attention to the impact on production and life, hygiene, transportation, agriculture and urban water supply, and power supply. The meteorological department recommends that the public should do a good job of preventing heatstroke and cooling, and try to avoid outdoor activities during high temperature hours. Personnel who work under high temperature conditions should shorten the continuous working hours. Relevant departments should provide heat prevention and cooling guidance in response to the old, weak, sick, and young people, and take necessary protection measures.

Pay attention to prevent fires caused by excessive electricity, as well as fire loads such as wires and transformers. Agricultural production needs to be irrigated in time to ensure the normal growth of crops.
