Is it a coincidence that it rains during the college entrance examination or is it a result of the weather?
Raining during the college entrance examination is not an accidental coincidence, but has certain meteorological laws and reasons.
First of all, we need to know that the college entrance examination is held in June, and June happens to be the time when both the south and north of my country enter the plum rain season or dragon boat season.
At this time, the south is affected by the South China Sea summer monsoon. Warm and moist airflow is continuously transported to Jiangnan, South China, Yunnan-Guizhou Plateau and other regions. When it meets the cold air from the north, heavy precipitation will form. In the north, affected by the Northeast Cold Vortex, thunderstorms and strong convective weather will also occur.
Therefore, the college entrance examination period coincides with the active monsoon period. Abundant water vapor and strong upward movement lead to a greatly increased probability of rainfall.
Secondly, we should also note that the college entrance examination period is often a time when typhoons generate and land frequently. From June to October every year, typhoon activity in the northwest Pacific is most intense. After a typhoon forms at sea, it will change its path and intensity due to the influence of subtropical high pressure, equatorial low pressure trough, cold air and other factors.
Once a typhoon approaches or lands in my country's coastal areas, it will bring strong winds and heavy rain to the vast area. Typhoons have a wide impact on rainfall, not only affecting coastal areas but also inland areas.
For example, from June 9 to 10, 2019, Typhoon No. 2 "Lekima" moved northwest after landing in Zhejiang, triggering widespread heavy rains in Jiangsu, Anhui, Henan and other places. And it happened to be the second day of the college entrance examination.
Finally, we have to consider the human factor. Some people may wonder whether the rain during the college entrance examination was caused by artificial rainfall. In fact, there is no basis for this statement. Artificial rainfall can only catalyze under the conditions of clouds and rain, but cannot create clouds and rain.
And artificial rainfall must follow certain procedures and specifications and will not be carried out randomly. What's more, at such an important moment as the college entrance examination, artificial rainfall is even less likely to interfere with the candidates.
To sum up, raining during the college entrance examination is not a mysterious phenomenon, but has certain meteorological laws and reasons. Raining during the college entrance examination is not necessarily a bad thing. Sometimes rain can lower the temperature and relieve the nervousness of the candidates. It can also wash away dust and pollutants in the air and improve the air quality.
Of course, rain during the college entrance examination will also bring some inconvenience to the candidates, such as traffic jams, wet clothes, and low mood. Therefore, candidates should pay attention to weather forecasts and warning information during the college entrance examination, take rainproof measures in advance, arrange travel time reasonably, maintain a good attitude, and successfully complete the exam.
