What weather is very humid?

Weather with atmospheric humidity exceeding 70%. Such as cloudy days and rainy days.

Atmospheric humidity refers to the degree of humidity in the air, indicating the degree of water vapor content in the atmosphere from atmospheric saturation at that time. Generally speaking, the degree of atmospheric humidity is expressed as a percentage of relative humidity. At a certain temperature, the smaller the relative humidity in the atmosphere, the faster the evaporation of water vapor; On the contrary, the greater the relative humidity in the atmosphere, the slower the evaporation of water vapor. In people's real life, the dry air in winter and spring and the sultry weather in summer are all due to the change of humidity in the atmosphere.
