Why can Shanghai have high temperature, hail, strong wind, thunder and lightning and heavy rain at the same time?

It is normal to answer the high ticket with amateur aviation meteorological knowledge. That's right. High temperature is high temperature, and thunderstorms, strong winds and hail are all strong convective weather, that is, high water vapor content+high temperature will lead to local thunderstorms in the afternoon. In aviation meteorology, it is called Cumulonimbus Cloud (TCU) and Cumulonimbus Cloud (CB). After the cumulonimbus cloud develops into CB, there will be lightning, precipitation, strong wind and wind shear. Hail Many people think that hail, like snow, only appears in winter. In fact, hail is the product of strong convective weather in summer, which is that rain suddenly cools to a solidified state in cumulonimbus clouds and then falls. You can refer to Baidu: "The water on the local surface is evaporated by the sun and then rises into the air. A lot of water vapor condenses into clouds. When it is liquefied by cold air, it takes the dust in the air as the condensation core to form raindrops, which are getting bigger and bigger, and no amount of clouds can hold it. It will rain. If you encounter cold air without condensation nuclei, water vapor will condense into ice or snow, which means it will snow. If the temperature drops sharply, it will form a larger ice mass, which is hail. " In civil aviation flight, it is forbidden for aircraft to cross cumulonimbus clouds. The airflow in the cumulonimbus cloud is very chaotic, and there will be any bad weather. Of course, we should try not to fly directly under the cumulonimbus cloud, which is the hardest hit by thunderstorms. Planes usually choose to fly around or fly at high altitude over cumulonimbus clouds, but it turns out that it is not safe to fly over the top of CB. A flight 330 has been like this before ... and then, hehe, all kinds of bumps, ap drops sharply, speed increases, overload increases ... and then local authorities intervene.
