Climate is the statistics of weather, usually over a 30-year interval. It is measured by assessing the patterns of variation in temperature, humidity, atmospheric pressure, wind, precipitation, atmospheric particle count and other meteorological variables in a given region over long periods of time.
Once you have the saturation vapor pressure and the actual vapor pressure, relative humidity can be computed by dividing the actual vapor pressure by the saturation vapor pressure and then multiplying by 100 to convert the quantity to a percent. (7) Relative Humidity(RH) in percent =(E/Es)*100.
Best Answer: Ah Judy, there isn't such a thing as an average relative humidity. This is because it changes a lot only in the course of the day. How much moisture the air can contain depends on the temperature. The warmer it is, the more moisture it can contain. That is the absolute humidity that is the volume of water per volume of air. The relative humidity, which is what you measure with a hygrometer, is the percentage of moisture to achieve full saturation for a given temperature. But since the temperature varies a lot during the course of a day, so does the relative humidity.
