A virial equation was used as a model equation of state to obtain expressions for. Looking at the table, 7.984 mb is somewhere between 7.580 (a temperature of 3 o Celsius) and 8.135 (a temperature of 4 o Celsius). kg dry carbon dioxide, the humidity ratio and the relative humidity. Using the lookup table below the calculator, we need to determine the temperature which corresponds the closest to the actual vapor pressure, in this case a vapor pressure of 7.984 mb. Once we have this value, we can forecast the current temperature dewpoint in degrees Celsius. What is the actual vapor pressure, given that the atmosphere is only at 65% of its capacity? The calculator provides a value of 7.984 mb of pressure. The vapor pressure of a saturated atmosphere at the given temperature calculates (click on the "Evaluate" button) to 12.283 mb of pressure. Once we have calculated the SVP, we can adjust it for an atmosphere that is less than completely saturated:Īctual vapor pressure (VP) = SVP x RH / 100įor example, in the calculator below, the input values are 10.0 o Celsius with a relative humidity of 65%.

The mixing ratio is calculated in different ways with different types of information. Once you have the actual mixing ratio and the saturation mixing ratio, you can use the following formula to calculate relative humidity. Saturated vapor pressure (SVP) = 6.11 x 10 ((7.5T)/(T+237.3)) For example, in the calculator below, the input values are 10.0 o Celsius with a relative humidity of 65.

Given these two values, how might one "forecast" a temperature dewpoint? A series of algorithms, or calculations, can be performed to determine the vapor pressure of water (in millibars, or mb) if the atmosphere is saturated (i.e, if the relative humidity is 100%) or the actual vapor pressure if the atmosphere is not completely saturated.
