Executive summary:According to the monitoring of the National Climate Center, since June this year (as of July 12), the average number of high temperature days in my country has been 5.3 days, which is 2.4 days more than the same period of normal years, the most in the same period since 1961. At the same time, monitoring by the National Climate Center showed that in June this year, the global average temperature was about 0.4°C higher than normal, the highest since 1979.
Tianjin North Net News:According to the monitoring of the National Climate Center, since June this year (as of July 12), the average number of high temperature days in my country has been 5.3 days, which is 2.4 days more than the same period of normal years, the most in the same period since 1961. At the same time, monitoring by the National Climate Center showed that in June this year, the global average temperature was about 0.4°C higher than normal, the highest since 1979.
In the past few days before and after entering Fufu, Jincheng also switched to “barbecue mode” with Fufu, and high temperature weather continued to appear. On the occasion of entering abbot, many parts of the country also greeted the abbot with the enthusiasm of the summer heat. Among them, the Central Meteorological Observatory continued to issue a high-temperature yellow warning at 6:00 a.m. on the day it entered the apocalypse on the 16th. This is the 12th consecutive day that the Central Meteorological Observatory has issued a high-temperature warning. Since mid-June, many places in my country, including Tianjin, have turned on the “high temperature mode”. In late June, Tianjin City had a high temperature of 40°C+.
Taking the 15th day before entering Fuyu as an example, the highest temperature in the city was about 36℃; on the day of entering Fufu on the 16th, the highest temperature was about 35℃; yesterday’s temperature was also about 35℃… These three days, Tianjin City ushered in “proper” The high temperature weather, plus the characteristics of high humidity and high temperature after entering the Futian for the next two days, brought a sultry day with high temperature and high humidity. This is just the beginning of the Futian.
According to reports, the highest temperature in the city usually occurs in June. During the dog days, in fact, the temperature may not be the highest in summer, but it is the most uncomfortable in terms of body feeling. The dual weather characteristics of high temperature and high humidity make the sultry feeling It is more obvious, and the body sense is more sensitive to the sultry heat.
Since June this year, over the subtropical regions of the northern hemisphere, the western Pacific subtropical high pressure belt, the Atlantic high pressure belt and the Iranian high pressure belt have all strengthened in stages, thus forming a large-scale global warm high pressure belt. Under the control of the warm high-pressure zone, the prevailing downdraft is conducive to the warming of the ground. In addition, under the action of the large-scale high-pressure zone, the air is relatively dry, and it is not easy to form clouds, which also makes it easier for solar radiation to reach the ground, resulting in frequent high temperature occurrences , and the intensity is strong, resulting in high temperature and heat waves in many places in the northern hemisphere, including Tianjin.
Since late June, the subtropical high pressure has moved northward, especially after the typhoon “Siamba” moved northward in early July. The temperature extreme in Tianjin this year, the temperature of 40℃+ also appeared in late June. In addition, due to the water vapor carried by the “subtropical high” and the water vapor brought by rainfall, the air humidity is increased, and the high temperature also highlights the characteristics of sultry weather. It is different from the previous people who only faced dry and hot weather. Taking the maximum temperature of 35°C as an example, people’s body temperature will reach about 40°C. Therefore, during the dog days, people not only face high temperature but also high humidity, which is also the main reason for the most difficult dog days.
With the gradual southward movement of the western section of the subtropical high, it is expected that the high temperature weather in the Sichuan Basin, Shaanxi Guanzhong, Jianghan, Jianghuai, northern Jiangnan, and northwestern South China will ease from the 17th to the 20th.
In Tianjin, in the dog days, although the highest temperature is between 33-35 ℃, but the humidity is high, the human body feels sultry, and the public is reminded to pay attention to hydration and cooling. Reduce the time of outdoor activities under the hot and scorching sun, try to avoid the stimulation of strong light and high temperature on the human body, and avoid heat stroke. In the early stage of continuous high temperature and heat, the weather was unstable. Last night, scattered thunderstorms appeared. For three days from today, the city’s high temperature and high humidity will continue, and the sultry feeling is obvious. Go out to prevent heatstroke and cool down.
Although the high temperature has weakened under the influence of thunderstorms and other weather in the future, it does not mean that it will be cooler. After entering the apocalypse, the temperature in Tianjin is high, the air pressure is low, the humidity is high, and the wind speed is low. According to meteorological monitoring and analysis, it will be cloudy to sunny during the day, with breeze, the highest temperature is 34 ℃, and the lowest temperature is 25 ℃.
