moist_static_energy#

metpy.calc.moist_static_energy(height, temperature, specific_humidity)[source]#

Calculate the moist static energy of parcels.

This function will calculate the moist static energy following equation 3.72 in [Hobbs2006].

Parameters:

• height (pint.Quantity) – Atmospheric height

• temperature (pint.Quantity) – Air temperature

• specific_humidity (pint.Quantity) – Atmospheric specific humidity

Returns:

pint.Quantity – Moist static energy

Examples

>>> from metpy.calc import moist_static_energy
>>> from metpy.units import units
>>> moist_static_energy(1000 * units.meters, 8 * units.degC, 8 * units('g/kg'))
<Quantity(312.275277, 'kilojoule / kilogram')>

Notes

$$\text{moist static energy}=c_{pd}T+gz+L_{v}q$$

• $T$ is temperature

• $z$ is height

• $q$ is specific humidity

Changed in version 1.0: Renamed heights parameter to height
