What's the weather like in Nantian?

Huinantian is the name of a humid weather phenomenon in southern China in spring, which is characterized by high temperature and rising humidity.

1. People will think that it is rainy in Huanan, because it always comes with rainy days. In fact, returning to the south is not a rainy day, but a resurgence phenomenon. When a cold air strikes, the surrounding temperature will drop, and water vapor will form ice crystals and attach to the wall. As soon as the cold air leaves, the warm air will attack, and these ice crystals will melt into a large number of water droplets when they are warm. It is also possible that cold air meets warm air, and strong warm air flow will also cause a lot of water mist, and warmer days will be born.

2. The formation of Returning to the South Sky can actually be answered from the physical aspect, which is a physical phenomenon. In physics knowledge, water vapor will freeze when it is cold and melt into liquid when it is hot, that is, water vapor will saturate and condense when the temperature is less than or equal to the dew point. At this time, when the warm air strikes back, it will liquefy into water droplets, much like the formation of sea fog. When the water vapor at sea encounters a large temperature difference, it will form fog drops, and when it accumulates to a certain extent, it will form a sea fog day.

3. Going back to Nantian mainly occurs in the coastal areas of South China, because in spring, warm sea breeze begins to blow in these areas, and at this time, the cold air still does not stop. As long as there is cold air going south and encountering warm sea breeze, there will naturally be serious resurgence. Once the warm weather is ushered in, we must take moisture-proof measures.
