bunkers_storm_motion

metpy.calc.bunkers_storm_motion(pressure, u, v, height)

Calculate the Bunkers right-mover and left-mover storm motions and sfc-6km mean flow.

Uses the storm motion calculation from [Bunkers2000].

Parameters

• pressure (pint.Quantity) – Pressure from sounding

• u (pint.Quantity) – U component of the wind

• v (pint.Quantity) – V component of the wind

• height (pint.Quantity) – Height from sounding

Returns

• right_mover (pint.Quantity) – U and v component of Bunkers RM storm motion

• left_mover (pint.Quantity) – U and v component of Bunkers LM storm motion

• wind_mean (pint.Quantity) – U and v component of sfc-6km mean flow

Notes

Only functions on 1D profiles (not higher-dimension vertical cross sections or grids). Since this function returns scalar values when given a profile, this will return Pint Quantities even when given xarray DataArray profiles.

Changed in version 1.0: Renamed heights parameter to height
