Air moisture content

The water vapor content per cubic meter of air is about 4 ~ 40g/m3, and the water content of 15g/m3 is relatively small. Therefore, in winter, due to the low temperature, the air contains less water, so it will feel wet and cold, and sometimes there will be clouds, rain and snow. When the temperature is high in summer, the air contains more water and less water vapor, there will be sunny and dry weather.
