Is it a coincidence or is it due to the weather that it often rains during the college entrance examination? Question | Holding | Climate
On June 7th, 2023, the college entrance examination officially kicked off. The reporter learned from the China Meteorological Administration that on the second and third days of the college entrance examination, the main weather affecting China is still mainly rainfall and high temperatures.
According to the forecast of the Central Meteorological Observatory, there are two main rain areas in my country during the college entrance examination, which are located in the Yangtze River Basin and its south and Northeast North China.
Sun Jun, chief forecaster of the Central Meteorological Observatory, introduced that affected by the water vapor on the north side of the subtropical high, from June 7 to 10, there will be an obvious rainfall process in the middle and lower reaches of the Yangtze River and the south of the Yangtze River from north to south, Jiangnan, South China, Yunnan-Guizhou Plateau, There will be moderate to heavy rains in southern Sichuan and heavy rains locally. Some areas will also be accompanied by short-term heavy precipitation, local thunderstorms and strong winds.
Northeast and North China rainfall is mainly affected by the northeast cold vortex. From the 7th to the 10th, there will be many showers or thunderstorms in North China, Huanghuai, Northeast China, eastern and southern Qinghai, and strong convective weather such as thunderstorms or hail may be accompanied locally from afternoon to night.
"It rains as soon as you get to the college entrance examination", "10 years of college entrance examination and 8 years of rain", is this a coincidence or a climate?
In this regard, meteorological experts said that this is actually related to the time of the college entrance examination. Before 2003, the time for the college entrance examination in our country was once set in July. At that time, rushing for the examination was to some extent like "baking". Therefore, in the memory of "post-60s" and "post-70s", the college entrance examination is always bound with ice cubes, cooling oil, mung bean soup and other "summer relief artifacts.
Generally speaking, candidates are more nervous when taking the college entrance examination. If they are in an environment with high temperature and poor ventilation, they will accelerate perspiration, lose a lot of water, salt, and electrolytes in the body, and they are more prone to heatstroke than usual. Therefore, the high temperature weather is likely to affect the normal performance of the candidates.
As a result, the meteorological experts at that time analyzed the data from 1971 to 2000 and found that the average temperature of the second climate in June was significantly lower than that of the second climate in July. At the same time, the relative humidity in June was also lower than that in July, and the average incidence of typhoons and floods was also smaller than that in July.
Therefore, in 2003, the Ministry of Education accepted the recommendation of the Meteorological Department to change the time of the college entrance examination from July, which has been implemented for many years, to June. Since then, the examinee experience high "roast" situation greatly improved.
However, this also brings new problems. It rains as soon as the college entrance examination arrives.
Meteorological experts explained that China generally enters the main flood season in June. At this time, the summer monsoon firmly controls East Asia, while most of the eastern part of China is a typical monsoon climate zone, so there is more precipitation in the areas affected by the monsoon.
At the same time, June and July each year is the "rainy season" in South China and Jiangnan ". Therefore, it rains as soon as the college entrance examination is held, which is actually more prone to precipitation during this period.
From a psychological point of view, although different regions may encounter different weather processes during the annual college entrance examination, high temperature and rainfall have a greater impact on the examination and leave people the most impressive, so they are more likely to receive attention.
In view of rainfall and severe convective weather, experts remind candidates and parents to pay close attention to weather forecast information, carry rain gear, and estimate the impact of good weather on traffic.
