equivalent_potential_temperature

metpy.calc.equivalent_potential_temperature(pressure, temperature)[source]

Calculate equivalent potential temperature.

This calculation must be given an air parcel’s pressure and temperature. The implementation uses the formula outlined in [Hobbs1977] pg.78-79.

Parameters:
  • pressure (pint.Quantity) – Total atmospheric pressure
  • temperature (pint.Quantity) – The temperature
Returns:

pint.Quantity – The corresponding equivalent potential temperature of the parcel

Notes

\[\Theta_e = \Theta e^\frac{L_v r_s}{C_{pd} T}\]
