Comprehensive Zhejiang weather, Zhejiang news
"At noon on a hot day, the fire is burning", although we have not yet entered the ambush, we have experienced the high-end version of the three-volt day in advance! Go out to do a nucleic acid on the free steam a sauna, walk a corner to meet all the "acquaintance" people, this year all rely on air conditioning in the continuation of life!
How hot is it?
Under the support of subtropical high pressure, our province has been rolling in since the 6th, and this high temperature heat wave has rolled in!
Take Hangzhou as an example, including today, it has been under the high temperature for 8 consecutive days! And the intensity is not inferior, since yesterday, the highest temperature in Hangzhou for two consecutive days rushed to the head of 4 (today's highest 40.3 ° C), what a hot word!
It's still a daunting hot day! A total of 28 places in our province rushed into the 40 °C army! Among them, Yuyao and Lishui can be called "the hottest furnaces today", with the highest temperature reaching 41.2 °C!
Do you think you'll be cooler sooner or later? Wrong! The heat is available all day, and there is no chance to breathe
Do you know? Yesterday's Hangzhou high temperature continuous online time for 12 hours, until last night 10 o'clock "turned off", and today at 9 o'clock, the high temperature and non-stop to "go to work"! When will the heat stop tonight? Sincerely hope it can steal a little lazy ~
In the next ten days, our province will continue to have sunny, hot and hot weather
It is expected that the province will continue to have sunny and hot hot weather in the next ten days, and more scattered thunderstorms in the afternoon.
Among them, before the 16th, the province continued to be extremely hot, and the maximum temperature in most areas was 38 to 41 °C, and the local temperature was above 41 °C; On the 17th and 18th, there are a large range of showers or thunderstorms, and there are strong convective weather such as short-term heavy rain and 8-10 thunderstorms and strong winds, and the high temperature is slightly moderated.
After the 19th, the high temperature intensity will be strengthened again, and the maximum temperature in most areas will rise to 38 to 40 °C.

Why is it so hot this year?
Widespread heat is normal in the summer, but this year is unusual.
Mao Yanjun, senior engineer of the Zhejiang Provincial Climate Center, compared the historical meteorological data of Zhejiang Province and gave a "extremely high temperature" answer. "In terms of intensity and time, there are indeed certain extremes in this year's hot days. For example, 2003 and 2013 were also high temperature years, but it was not until late July to early August that the extreme heat above 40 °C appeared. ”
According to the statistics of the Provincial Climate Center, the average temperature in the province in early July was 2.4 °C higher than that of the same period of the year, and the number of local high temperature days in Quzhou, Jinhua and Ningbo in the past 20 days even reached 15 days or more.
Mao Yanjun then analyzed: "There are two significant performances, one is that the time of extreme high temperature days is significantly earlier than in previous years; Second, the subtropical high pressure firmly controls our province this year and is abnormally stable. ”
From this point of view, the "culprit" of this wave of high temperature is the subtropical high pressure. But a new problem has emerged, Zhejiang has also been controlled by subtropical high pressure in the summer in previous years, why is it particularly hot this year?
Originally, Zhejiang is currently in the western Pacific subtropical high pressure western extension ridge control area, that is, the center of the subtropical high pressure, and this year's subtropical high pressure enhancement cycle coincides with the perennial high temperature period, resulting in a superposition effect, so the intensity is stronger than in previous years. It is conceivable that we now have a 24-hour uninterrupted super heater above our heads, steadily transporting hot air, and the temperature rises naturally and rapidly.
The State of the Global Climate 2021, recently released by the World Meteorological Organization (WMO), mentions that 2015-2021 will be the hottest 7 years on record. Globally, countries such as Spain, Italy, Norway, Japan, Iran and Finland have also recently experienced hot weather, and India has also suffered the strongest heat wave in 122 years.
"Climate change is a slow process of 'boiling frogs' and has relative stability, but according to the data accumulated data, the probability of extreme weather has increased significantly in recent years." Mao Yanjun believes that extreme weather has suddenness, there is great uncertainty in the time and landing area, monitoring and prediction are relatively difficult, and what humans can do in addition to adapting to the climate is to minimize greenhouse gas emissions.
How long will this heat wave last?
After research and judgment, Mao Yanjun brought good news, "According to the cyclical changes in atmospheric circulation, there are signs of increased showers in our province over the weekend, and the extreme heat in some areas may be alleviated." ”
In meteorology, when the temperature is above 35 ° C, it can be called "high temperature weather", and if the maximum temperature exceeds 35 ° C for several consecutive days, it can be called "high temperature heat wave".
Ma Xinyu, chief expert of the Zhejiang Meteorological Service Center, told reporters that although the impact of the high temperature heat wave is more of a slow accumulation process, not as direct as the weather phenomena such as heavy rain and typhoons, the continuous high temperature heat wave will cause people, animals and plants to be unable to adapt and have adverse effects, and agriculture, transportation, water conservancy, electricity and other relevant departments need special attention and take preventive measures in advance.
"Especially this year's rainy period is relatively short, we should pay attention to drinking water, drought, forest fire risk and other issues, and timely carry out water resources dispatch." Ma Xinyu reminded.
In fact, early rice in some areas has a mild "high temperature ripening" hazard, and some areas of citrus have a "sunburn" phenomenon. Experts from the Provincial Agricultural Meteorological Center reminded that the relevant parties should do a good job in time such as field irrigation and facility agricultural coverage and shading, suspend some wild high-temperature agricultural activities according to the high temperature situation, and pay attention to the excessive reaction of fish and shrimp in aquatic products.
In order to ensure the irrigation water source, the reporter learned from the Provincial Water Conservancy Department that as of July 10, the province has completed 1566 agricultural irrigation port pump stations and weir dam sluice upgrading projects, with a completion rate of 104.4%, benefiting more than 400,000 mu of irrigation area and nearly 1 million farmers.
Artificial rain augmentation is already being deployed across Zhejiang
In response to the midsummer heat, various departments have actively carried out action. At present, artificial rain increase operations in various parts of the province have been intensively deployed, such as Huzhou and Taizhou's coastal areas have carried out rocket operations and smoke furnace operations respectively, and the Hangzhou Meteorological Bureau will carry out rain increase operation training exercises this week. Cheng Ying, deputy director of the Provincial Artificial Influence Weather Center, said that in the near future, they will closely monitor weather changes and carry out rain-increasing operations in a timely manner.
Wary! The "Summer Killer" in the Heat
Heat stroke
For ordinary people, during the day from 10:00 to 15:00 to minimize going out, avoid outdoor open work, especially the elderly and the infirm as far as possible to take air conditioning cooling, beware of heat stroke or heat stroke.
