   1 Definition of virtual temperature. For dry air, the equation of state is. pd = rdRdT: (1) Similarly, water vapor obeys its own equation of state and has its own gas constant: e = rvRvT: (2) Here Rd and Rv are the mixing ratios of water vapor and dry air, respectively.

   The virtual temperature concept, T v, comes from wanting simplify the ideal gas law by pretending that all of the molecules are dry molecules and adjust the temperature to get the pressure to come out correctly using R (=R dry) while at the same time keeping the total density correct to satisfy the hydrostatic equation. !

   What is a virtual temperature?

   • So, what is it? The virtual temperature is the temperature a dry air parcel would need to have to have the same density as the moist air, provided that they had equal volume and pressure. Density measures the unit of mass per volume, and because molecules of elements have different masses, changes in composition affect the air parcel density.

   What is the virtual temperature of dry air?

   • Hence the virtual temperature is the temperature that dry dry air would have if its pressure and density were equal to those of a given sample of moist air. For typical observed values of rv, the virtual temperature may be approximated by Tv = (1 + 0.61 rv) T.

   What is a virtual temperature calculator?

   • The virtual temperature calculator The virtual temperature calculator uses two methods to obtain the result, so we'll cover both of them: The first virtual temperature formula is derived from the equation of state for air, also known as the ideal gas law – this time, for moist air.

   Calculating Virtual Temperature (Tv) The presence of water vapor in the air influences the temperature, pressure, and density of the air. Meteorologists substitute the virtual temperature (Tv) for the actual temperature (T) when making calculations in which temperature is a variable.
