To calculate the mean virtual temperature with the hypsometric equation, you have to rearrange it to the following form: Tv=gz2−z1Rdln⁡(p1p2)T_v = g \\frac{z_2 - z_1}{R_d \\ln{\\left(\\frac{p_1}{p_2}\\right)}}Tv​=gRd​ln(p2​p1​​)z2​−z1​​ where:
ggg – Gravitational constant;
p2, p1p_2, \\ p_1p2​, p1​ – Upper and lower pressure levels;
z2, z1z_2, \\ z_1z2​, z1​ – Upper and lower heights the pressure levels are at;
RdR_dRd​ – Dry air gas constant; and
ln⁡\\lnln – Natural logarithm.
