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.
Step 2: Vapor Pressure. Relative humidity can be expressed as a ratio of the saturation vapor pressure at the dew point temperature to the saturation vapor pressure at the air temperature. This is expressed by the formula RH = 100*(e/e s).or example, a dew point temperature below freezing indicates very dry air. On the other hand, a dew point temperature of 70 degrees F would occur on a humid, muggy day. Below you will find the step by step process that will teach you how to calculate dew point.
