The weather is closely related to our life.

Most importantly, the weather affects people's mood. On cloudy days, when the atmospheric pressure is low and the solubility of gas decreases, there is less oxygen in the air, and people will feel depressed and unhappy. When the weather is clear, the air pressure is high, and the gas solubility is also increased. People breathe in more oxygen and feel better.

In addition, the weather is good, people's production and life are convenient, and it is not too difficult to travel ... Anyway, sunny days are better than rainy days (only in rainy areas in the south of the Yangtze River)
