Is the high temperature in the north abnormal?How long will it last?

During the Dragon Boat Festival holiday, a large -scale, continuous high temperature weather appeared in northern my country.From June 22 to 16:00, Beijing -Tianjin -Hebei, Shandong, central and northern Henan, northern Anhui, northern Jiangsu, and western Inner Mongolia, eastern Xinjiang and southern Xinjiang Basin appeared above 35 ° C.

Among them, the temperature in Beijing, Tianjin, central Hebei, and northern Shandong has risen rapidly, and the highest temperature rises to above 40 ° C.The maximum temperature of the maximum temperature in Beijing, Tianjin, Hebei, and Shandong exceeded the historical pole of the highest temperature.

The national temperature rankings on June 23 are difficult to appear below 35 ° C.

"It’s so hot!" Many tourists traveling during the holidays screamed directly.

After comprehensive research and emergency consultation, the China Meteorological Administration launched a major meteorological disaster (high temperature) level four emergency response at 09:00 on the 23rd.The Central Meteorological Observatory continued to issue high -temperature orange warnings this morning. Beijing Meteorological Observatory also upgraded the high -temperature red warning signal this morning.

Is this round of high temperature abnormal in the north?What causes such hot weather?How long will it last?Will it be hotter in July and August?On the afternoon of June 23, experts from the National Meteorological Center responded in an interview with surging news.

Beijing Guanxiangtaijian Station has been over 40 ° C for the first time since the first time

Affected by the heating group and strong solar radiation, on the 22nd, most areas above 39 ° C appeared above 39 ° C. The highest temperature of the viewing table was 41.1 ° C, and the historical pole value in June was exceeded (the extreme maximum temperature of the viewing table in June was 40.6 ° C, and it appeared in 1961 in 1961.June 10).Among the city’s 556 meteorological monitoring stations, 454 test stations have a maximum temperature of 39 ° C and above, and the maximum temperature of 265 test stations is 41 ° C or above.

As of 14:00 on the 23rd, the temperature of the viewing table has reached 40 ° C (appearing at 13:36). The maximum temperature of 305 of the 556 meteorological monitoring stations in the city is 39 ° C and above.Essence

"For the first time since the Guanxiangtai Station, it has exceeded 40 ° C for the first time." Zhang Yingxin, chief forecaster of Beijing Meteorological Observatory, said that the high temperature weather continued from the 23rd to 25th, and the maximum temperature in most regions was 37 ° C to 40 ° C; of whichThe maximum temperature can reach about 40 ° C from the 23rd to 24th.The Beijing Meteorological Observatory has been upgraded to the high -temperature red warning signal at 07:00 on June 23.

Zhang Yingxin said that Beijing’s high temperature strength and long duration of this round are mainly based on the following points: First, the Beijing -Tianjin -Hebei region is controlled by the heating group on the 21st.Under the control of the high -pressure ridge situation, the sky is clear and cloudy, without clouds cover, radiation temperature increases is more favorable, and the temperature is promoted; third, the current summer solstice solar term, the longest day, long -term sunlight is conducive to the appearance and maintenance of high temperature; the fourth is air.Small humidity and dry weather are also conducive to rising temperatures.

Since June, 46 national meteorological stations broke the historical pole value

Since June of this year (as of the 22nd), a total of 183 national meteorological stations have exceeded the monthly pole value of the highest temperature, and 46 stations break through the historical pole value.

Since June of this year (as of the 22nd), the number of high temperature days in North China is 6.4 days, 3.1 days more than the same period (3.3 days), the fifth place since 1961, second only to 1972, 1968, 2005, 2022.Beijing (7.9 days) has the most history since 1961, Hebei (7.8 days) is more than time, and Tianjin (6.1 days) is the third.

It is currently only at the end of June. Will the temperature be higher in July and August?

In this regard, Gao Hui, chief forecast at the National Climate Center, told Peng Mei News that since June (as of the 22nd), high temperature weather at 35 ° C nationwide is mainly distributed in North China, central and western South China, and most of Xinjiang.Among them, most of the high temperature daily days in North China are 6 to 10 days. The high temperature days in the western region of Hebei have reached more than 10 days. Compared with the same period of the same year, the high temperature days in the above areas are 3 to 5 days.above.

Gao Hui said that there are obvious geographical differences during high temperature concentration periods in various parts of my country.For North China, it is usually more likely to occur from June to early July before the rainy season. High temperatures for several consecutive days are more common in June.During this time, it is mainly dry thermal high temperature, which is manifested as low temperature and low humidity.

In the late July, with the deputy Gaobei jump and the summer wind to the north, water vapor transportation and atmospheric humidity increased, the amount of clouds would increase, and there would be sweltering weather, that is, the high temperature of humid and humid and humid.As far as the highest temperature is concerned, the highest temperature in the previous period is usually higher than the latter period.However, it is also necessary to explain that the human body temperature temperature is not only related to temperature, but also affected by humidity. Often, this humid and humid high temperature will increase the body temperature of the human body.

Under the background of global warming, high temperature breaking the historical extreme probability is greater

Gao Hui said that in the context of global warming, whether the frequency of extreme high temperature occurred in the south or north, the frequency of extreme high temperature increased rapidly.According to the forecast of the National Climate Center, the temperature in North China and Huanghuai and other places in my country this summer is high, accompanied by the number of high temperature daily, so this summer has a greater probability that the northern northern is hotter than usual.In this case, some stations have certain possibilities to break the extreme value of history.

This year is the development year of the El Nino incident. Is the high temperature in the north related to the El Niho incident?Gao Hui responded to Peng Mei News that it has entered the state of El Niho, but the impact factor of high temperature in the north in the early summer period is complicated, and it cannot be simply blamed as an El Nino influence."For example, in mid -to -late June last year, the high temperature in the northern region is more extreme, but last year was the year of La Na. In addition, the existing scientific research results also showed that the high temperature in the north in the early summer was more likely to be affected by the North Atlantic sea temperature and the atmospheric circulation of mid -to -high latitudes."

Zhang Fanghua, chief forecaster of the National Meteorological Center, said in an interview with surging news that two high -temperature weather processes have appeared in North China, Huanghuai and other places recently.Huanghuai and other places are controlled by strong heating groups, and it affects a long time; the second is that the sky is sunny and less cloudy under the control of high -pressure spine, and the temperature increase of solar radiation is more favorable and promotes the warming; thirdAt present, it is a summer solstice solar term. The daytime time is relatively long, that is, the time of the sunlight during the day is long. Long -term sunshine is conducive to the rise of temperature and the appearance and maintenance of high temperature. Fourth in North China, Huanghuai and other places, the air humidity is small.Dry weather is also conducive to the rise of temperature.

Zhang Fanghua said that after this round of high temperature, it is expected that from the 27th to 30th, high temperature weather will also occur in North China, Huanghuai and other places.

High -temperature days need to prevent heat stroke

What impact does this have on the Dragon Boat Festival during the Dragon Boat Festival?

Liu Yanxiang, chief service of the Public Meteorological Service Center of the China Meteorological Administration, said that the most direct adverse impact of high temperature weather on health is high temperature heat stroke.When symptoms of threatened heat stroke and mild heat stroke, headaches, dizziness, thirst, sweat, weakness of limbs, inadequateness, and uncoordinated movements will occur.It will relieve.However, if severe heat stroke occurs, it may cause arrhythmia, coma, convulsions, diarrhea, acute renal failure, liver failure, hypotension, shock, arrhythmia, heart failure, pulmonary edema and cerebral edema.Severe heat stroke, especially the risk of death caused by heat irritation.

There are also two types of thermal radiation disease, one is labor -type thermal radiation disease, mainly due to high -intensity physical activity caused by the body’s heat production and heat dissipation imbalance.Healthy young people who are common in summer outdoor strenuous exercise, such as officers and soldiers, athletes, firefighters, construction workers, courier, etc. who are participating in the summer.The other is a classic thermal radiation disease, mainly due to passive exposure to the heat environment that causes heat production and heat dissipation imbalance.It is common in young people, pregnant women, and old -fashioned bodies, and people with chronic basic diseases or low immune functions.In addition, the stuffy indoor and the car that does not turn on the air conditioner is also a place where heat stroke often occurs.

Liu Yanxiang reminded that the human body sweat a lot in high temperature weather, causing blood viscosity to increase, slower blood flow, and increased heart load, and the risk of cardiovascular and cerebrovascular diseases increased.
