wet_bulb_temperature

metpy.calc.wet_bulb_temperature(pressure, temperature, dewpoint)

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].

Parameters

• pressure (pint.Quantity) – Initial atmospheric pressure

• temperature (pint.Quantity) – Initial atmospheric temperature

• dewpoint (pint.Quantity) – Initial atmospheric dewpoint

Returns

pint.Quantity – Wet-bulb temperature

Notes

Since this function iteratively applies a parcel calculation, it should be used with caution on large arrays.
