The weather in Longyao is so dull, why doesn’t it rain?

Should be soon.

Generally, summer rainfall is generally caused by the simultaneous influence of cold air and warm and humid airflow, while muggy weather is a manifestation of increased water vapor in the atmosphere and high temperatures. This is also the reason why summer thunderstorms are approaching. The harbinger of rain in summer is mostly showers and thunderstorms. The conditions for their occurrence are that the weather was fine in the early stage, the temperature was high, and strong convection occurred in the air in local areas, causing a large amount of hot and humid air to rise sharply, causing cumulonimbus clouds to form. At the same time, the hot air in the atmosphere increases and the water vapor is sufficient. Although the temperature change is not large at this time, because the atmosphere contains a lot of water vapor, it has become saturated, making it difficult for the water on the ground to evaporate. Sweat is not easy to evaporate, so you will feel very hot and uncomfortable. This is because the air pressure begins to drop. There is a large accumulation of ions in the air.
