Will the eclipse affect the weather forecast?

Energy 1. The temperature dropped sharply. Looking up the report of China Southern Meteorological Station at that time, it was found that there were dozens of meteorological stations with solar eclipse observation records. The temperature change is most obvious in sunny Shenzhen. 10: 32, four minutes before the solar eclipse, the temperature in Shenzhen was 30.2℃. With the increase of lunar eclipse, the temperature changed from rising to falling, and the change was abnormal. During the solar eclipse (12: 1 1: 00), it dropped to 26.3℃, that is, it dropped by 3.9℃. After eating, the temperature rose again, and the last contact (13: 29) rose to 29.2℃, still not reaching the temperature before the solar eclipse. 2. The ground temperature changes more than the air temperature. This is because the temperature rises during the day and the cold and heat sources of the temperature drop at night are all on the ground. Unfortunately, there is no observation report on the surface soil temperature in Shenzhen, such as Shan County, Hainan. The temperature at the beginning of the eclipse is 32.4℃, and the temperature at the end of the eclipse is 30.2℃. In other words, due to the clouds in the sky, the temperature during the eclipse only dropped by 2.2℃. But the ground temperature dropped sharply from 42.9℃ to 32.5℃ (it rose to 5 1.4℃ after the last contact), that is, it dropped sharply 10.4℃! It is estimated that the change of ground temperature in Shenzhen is greater than that in Xi 'an. 3. The temperature change of solar eclipse is only slightly deeper than 10 cm. It is commendable that the qionghai city Meteorological Observatory observed the temperature every four minutes during the eclipse, which let us know that the lowest temperature during the eclipse did not occur during the eclipse, but occurred about half an hour after the eclipse, although the temperature was only 0.2℃ lower than that during the eclipse. The observation of underground temperature every 4 minutes in Qionghai also shows that the reverse drop of ground temperature caused by solar eclipse generally only affects the place slightly deeper than 10 cm, because soil is a poor conductor of heat. At the depth of underground 15 cm, the temperature will not decrease reversely during the solar eclipse. 4. The relative humidity of air rises obviously in the opposite direction. During the solar eclipse, the relative humidity of the ground atmosphere also changed greatly. It turns out that in general, when there is no solar eclipse, the highest temperature appears before afternoon (about 14), and the relative humidity drops regularly (because the temperature has been rising). However, during the solar eclipse, the relative humidity increased due to the decrease of inversion temperature. For example, in Shenzhen, from 7 1% at the beginning of the loss, it suddenly rose to 88% at the end of the food season. Although it returned to normal after eating, it dropped to 78% at the last contact, but it was still higher than in the past. The eclipse will turn noon into dusk and moonlit night. It is interesting to describe the changes in the sky during the solar eclipse. For example, the Guangzhou Meteorological Observatory recorded: "When eating, the brightness of the sun is very weak, about 80% weaker than usual, and the sun shines on people is not as hot as usual. The whole sky is like a moonlit night. " Guangxi Baise reported that "the ground is yellow-brown". Guangxi and Beihai describe the sky with "yellow and black" and "the sun is as weak as dusk" respectively. Lijiang, Yunnan recorded the change of cloud color, saying that "the cloud color in translucent cumulus clouds is light black and uneven". The most interesting thing is that the observation group of Lhasa Meteorological Observatory in Tibet recorded that the rooster crowed twice during the eclipse, and the rooster crowed several times the second time-it can be seen that even the rooster was cheated by the eclipse.
