metpy.calc.wet_bulb_temperature(pressure, temperature, dewpoint)[source]

Calculate the wet-bulb temperature using Normand’s rule.

This function calculates the wet-bulb temperature using the Normand method. The LCL is computed, and that parcel brought down to the starting pressure along a moist adiabat. The Normand method (and others) are described and compared by [Knox2017].

  • pressure (pint.Quantity) – Initial atmospheric pressure
  • temperature (pint.Quantity) – Initial atmospheric temperature
  • dewpoint (pint.Quantity) – Initial atmospheric dewpoint
