Around 39 ℃!This year Changsha may be hotter than previous years ...

"The lotus wind gives the aroma, and the bamboo dew is clearing." Today, the "small summer" belonging to the summer solar terms came quietly.

Changsha is also very important. The Municipal Meteorological Observatory today issued a high -temperature yellow warning signal: Today, Wangcheng District, Yuhua District, Liuyang City, Changsha County, Ningxiang City, Tianxin District, Furong District, Kaifu District, Yuelu District, high -tech zone the highest The temperature will rise above 35 ° C, please pay attention to prevent.

Changsha's temperature step by step

Do we welcome the hottest time?

Summer starts, but it hasn't reached the hottest time

Xiaoshu is the fifth solar term of summer, which means that the summer will officially begin. "Since May, the heat is wet, and it has been steamed in the sits." At this time, the earth's heat waves are vertical and strong, and most areas in my country are about to open the "barbecue mode" or "cooking mode".

The middle and lower reaches of Changsha where Hunan is located is generally controlled by the subtropical high -pressure, and "drought" weather often occurs.

China's weather network invested in the provincial capital -level city high temperature daily rankings during the perennial summer summer. The southern cities were almost "dominated". Changsha ranked fourth, with a high temperature number of 6.2 days, second only to Hangzhou, Fuzhou and Chongqing.

"The central and eastern part of my country belongs to the monsoon climate and has the characteristics of the same period of rain and heat. Therefore, at this time, at this time, the middle and lower reaches of the Yangtze River will experience the process from the beginning of plums to the time of the year. High temperature is relatively rampant. "Hu Xiao, chief meteorological analyst of China Weather Network, said.

Meteorological big data found that in addition to high temperature, precipitation also increased significantly during the summer summer. From the perspective of the year, the end of summer and early autumn is a period of rainfall. Among them, the summer heat is the most, and the average rainfall reaches 64.7 mm.

"Suddenly warm the wind, because of the small summer. The bamboo noise feels the rain, and the mountains have heard the thunder." The poem of the Tang Dynasty Yuanxuan vividly described the weather characteristics of the small summer solar terms: the heat waves, the cool wind, and the rain.

"Xiaoshu is a solar term that reflects the hotness of the weather. 'Xiao" shows that the weather is not the hottest. "Xie Yijun, chief expert of the climate forecast of the Climate Center of Hunan Province, introduced that after entering, the surface humidity becomes greater, and the calories absorbed more daily. The calories are small, and the heat of the surface layer has accumulated, and it is hotter every day.

When entering the Sanfu, the ground accumulated heat reached the highest peak, and the weather was the hottest. And July 16 this year began to enter, and the Sanfu Tian was 40 days long.

Entering the season with the most thunderstorms around the summer. Most of the thunderstorms occur in the afternoon to the evening, and often appear with strong winds and heavy rain, sometimes hail, which is easy to cause disasters.

At this time, the typhoon that landed in our country also began to increase, and sometimes it would be sent to nectar and cool, and it would also bring wind and storms and disasters, such as the typhoon "Siaba" just left.

"In the summer season, Hunan entered the rainy season and summer heat." Lu Kuidong, a senior engineer of the Institute of Meteorological Sciences, Hunan Province, introduced that after all years, after entering the summer solar terms, in addition to the rainy season in northwestern Hunan, Hunan was controlled in other parts of Hunan. Most of them are sunny and hot.

At this time, northwestern Hunan still needs to prevent heavy precipitation. Special attention should be paid to the harm of high temperatures on dual -season early rice and spring corn and other crops. The weather of "drought" also has a great impact on agricultural production. It is necessary to storage and drought in early water storage, and to carry out artificial rainfall operations in a timely manner.

Changsha may be hotter in July than in previous years

According to the Central Meteorological Observatory, during the small summer of this year, my country still maintains the general weather characteristics of all year round. High temperature and sunny heat and heavy rainfall coexist, which generally presents the sandwich weather pattern of "north -south rain and high temperature in the middle".

For Changsha people, as the typhoon "Siaba" gradually goes away, the large -scale precipitation of Xingcheng will temporarily retreat, and the summer heat will return to the "weather battlefield".

For this July, heatstroke prevention and drought resistance have become what everyone has to do. The July weather trend forecast of the Municipal Meteorological Observatory shows that the temperature in Changsha is expected to be high in July, with an average temperature of 30.5 ° C (29.3 ° C in the past year, 30.3 ° C in 2021), and the extreme maximum temperature of the month can reach about 39 ° C. The main high temperature period is 8 days. From the 14th, 18th to 26th.

In addition, in July this year, drought is still needed.

According to the meteorological department, the precipitation may be about 40 % of the less than 40 %, which is 100 mm (164.4 mm over the years, and 93.8 mm in 2021). Day, 15 to 17, 27 to 28.

The Changsha Meteorological Observatory issued a lightning yellow warning signal at 14:21 today: It is expected that Wangcheng District, Yuhua District, Liuyang City, Changsha County, Tianxin District, Furong District, Kaifu District, Yuelu District, and High -tech Zone will occur in the next 6 hours. There may be thunderstorm accidents, please strengthen prevention. The meteorological department reminded that in July, there are many streams. Pay attention to urban waterlogging caused by heavy precipitation in the short -term period and prevent thunderstorms.

The meteorological department reminds that under the premise of ensuring safety floods, the relevant departments do a good job of water storage and water and water to prepare for the droughts that may occur in the later period. Preparation of high power load. In July, there are many sunshines and high temperatures, which may cause ozone to exceed the standard, and you need to make preparations in advance.
