Pay attention to prevent the maximum high temperature of this year's high temperature.

Since July 6, high -temperature weather above 35 ° C in Xinjiang, the eastern part of the northwest, the eastern part of the northwest, the northwest, North China, Huanghuai, Zhejiang and other places. How long will this high -temperature weather last? what is the reason? What impact will it have on production and life? Fu Jiaolan, the chief forecaster of the Central Meteorological Observatory and senior engineer of Zhengyan, conducted interpretation.

The high temperature weather range, strong strength, and long duration

On July 7, central and western Inner Mongolia, eastern Gansu, central Shaanxi, central Shanxi, central and southern Hebei, Beijing, Tianjin, central and western Henan, western Hubei, southern Jiangsu, Shanghai, Zhejiang, eastern Chongqing, etc. ~ 38 ℃ High temperature, inner Mongolia Wuhai and Alashan, Yinchuan in Ningxia, Guanzhong, Shaanxi, Yuncheng in Shanxi, Yibin in Sichuan, and southwestern Chongqing reached 39 ~ 40 ° C. Affected by the high -pressure north of the subtropical high pressure, the scope of high temperature weather in the future will be further expanded, and continuous high temperature weather will occur in most of the south.

The Central Meteorological Observatory predicts that from the 8th to 10th, there will still be high temperature weather in parts of Xinjiang, western Inner Mongolia, and eastern parts of the northwest region. The maximum temperature can reach 37 ~ 39 ° C, and the highest temperature of the local area of ​​Guanzhong Plain, Zhejiang, Chongqing, Guizhou and other localities can exceed 40 ° C.

Fu Jiaolan said that the high temperature weather process is the most influential high -temperature weather this year, which has the characteristics of wide influence, strong intensity, long duration and other characteristics. It will be close to or break the pole value of the same period, and high temperature weather in some areas will last for 10 days or more.

High temperature weather is normal, but there is extremes

According to statistics from the Central Meteorological Observatory, since June of this year, my country has had two large -scale high -temperature weather processes. The last time from June 13th to 26th, the first regional high -temperature weather process appeared in central and southern North China, Huanghuai, Jianghuai, Jianghan and other places, covering a land area of ​​3.636 million square kilometers. The high -temperature weather process starting on July 6 has a wider range of influence and longer duration.

Fu Jiaolan believes that large -scale high -temperature weather in summer is normal, but this year's high temperature weather has a certain extreme in strength and duration, such as Sichuan, Gansu and other places to break through the historical extreme value. From July 4th to 7th, the average daily temperature in Sichuan Province ranked first in the same period of the same period, 2.8 ~ 6.8 ° C higher than the same period. The highest temperature in the Sichuan Basin was 5.6 ~ 11.9 ° C. On July 6, high temperatures above 37 ° C in Zhangye City, Gansu Province, and the maximum temperature of the local area exceeded 40 ° C, breaking through the historical pole value of the local 39.8 ° C.

Fu Jiaolan pointed out that high temperature weather is closely related to high -voltage and subtropical high -pressure on the mainland. In mid -June, the warm spine of the mainland was extremely strong, mainly to control the North China, Huanghuai and other places in my country, and the above -mentioned regions had continuous high temperature weather. In early July, Iran's high pressure developed abnormal development, and moved east to the northwest and southwest of China. At the same time, the subtropical high -pressure west extension was enhanced, and most of the southern parts of my country were controlled. Due to the high pressure spine, the eastern part of the Northwest, the eastern part of the southwest region, and the middle of the Yangtze River Central River Central River. The downstream areas and other places are prevailing in the air flow, mainly in sunny heat and rainy weather. In addition, due to the influence of solar radiation during the day, the temperature rises significantly.

It is necessary to prevent the effect of high temperature on power, agriculture and other aspects

Due to the high temperature and long duration of this time, it has adversely affected power supply, production and living water, vehicle travel, and agricultural production.

Fu Jiaolan suggested that all relevant departments need to pay attention to weather forecasting and early warning information, do a good job of power supply and water resource dispatch, and prevent cities and forest fires. Especially the high temperature duration in the middle and lower reaches of the Yangtze River requires strengthening defense work.

In addition, high temperature has a adverse effect on human health. High temperature and high humidity weather can cause the human body's immunity to decline and the possibility of heat stroke increased. The Central Meteorological Observatory predicts that during the day on the 8th, southwestern Hebei, central Shanxi and southern, northern Henan, northwestern Shandong, eastern Anhui, Shanghai, Zhejiang, northeast of Jiangxi, northwestern Hubei, central Shaanxi and southern Sichuan, eastern Sichuan, and southern Sichuan, in eastern Sichuan, and southern Sichuan,, in eastern Sichuan, Sichuan, in eastern Sichuan. Western and northern, southern Gansu, western Xinjiang, and Turpan Basin are more likely to occur. The public should minimize outing activities during the day, ensure sufficient sleep, replenish water in time, and do a good job in heatstroke and cooling, hygienic epidemic prevention, and drowning.

At the same time, we should also pay attention to preventing the adverse effects of high temperature on agricultural production. The high temperature in the northern region will accelerate the loss of soil in Gansu, Shaanxi and other places. Drought in medium -sized places in Shaanxi Pass will continue or develop. High temperature and droughts are not conducive to corn and cotton crops to grow. Take management measures in time. High temperature is also unfavorable to the growth of rice and cotton in the middle and lower reaches of the Yangtze River, and it is easy to cause high temperature in early rice in the grouting period. It is necessary to strengthen field management and reduce the impact of high temperature heat damage.

Do a good job of response according to high temperature warning

In terms of meteorology, the temperature can be called "high temperature weather" when the temperature is above 35 ° C. If the maximum temperature exceeds 35 ° C for a few days in a row, it can be called "high temperature heat wave". High -temperature heat wave refers to a meteorological disaster that has a continuous high temperature process. Due to the longer temperature duration, causing people, animals and plants to adapt and cause adverse effects.

According to Fu Jiaolan, according to the scope, strength and duration of high temperature influence, and the harm that may be caused. The highest level. When a high -temperature yellow warning is issued, relevant departments and units should prepare for heatstroke prevention and cooling in accordance with their duties, minimize outdoor activities in the afternoon, and provide heatstroke prevention and cooling guidance for old, weak, sick, and young people; Personnel who perform outdoor open -air operations shall take necessary protection measures.

When a high -temperature orange warning is issued, try to avoid outdoor activities during high temperature periods. Personnel who work under high temperature conditions should shorten the continuous working hours; take necessary protection measures for old, weak, sick, and young people; pay attention to preventing electricity consumption. Excessive high, and fire loads such as wires and transformers are too large.

When a high -temperature red warning is issued, outdoor open -air operations should be stopped as much as possible; protective measures should be taken for old, weak, sick, and young people, and special attention should be paid to fire safety.
