earthkit.meteo.thermo.xarray.virtual_temperature¶
- earthkit.meteo.thermo.xarray.virtual_temperature(t, q)¶
Compute the virtual temperature from temperature and specific humidity.
- Parameters:
t (
xarray.DataArray) – Temperature (K)sq (
xarray.DataArray) – Specific humidity (kg/kg)
- Returns:
Virtual temperature (K)
- Return type:
xarray.DataArray
The computation is based on the following formula [Wallace2006]:
\[t_{v} = t (1 + \frac{1 - \epsilon}{\epsilon} q)\]with \(\epsilon = R_{d}/R_{v}\) (see
earthkit.meteo.constants.epsilon).
