wrf.rh¶
- wrf.rh(qv, pres, tkel, meta=True)¶
Return the relative humidity.
This is the raw computational algorithm and does not extract any variables from WRF output files. Use
wrf.getvar()
to both extract and compute diagnostic variables.- Parameters:
qv (
xarray.DataArray
ornumpy.ndarray
) – Water vapor mixing ratio in [kg/kg] with at least three dimensions. The rightmost dimensions are bottom_top x south_north x west_east.pres (
xarray.DataArray
ornumpy.ndarray
) –Full pressure (perturbation + base state pressure) in [Pa] with the same dimensionality as qv.
Note
This variable must be supplied as a
xarray.DataArray
in order to copy the dimension names to the output. Otherwise, default names will be used.tkel (
xarray.DataArray
ornumpy.ndarray
) –Temperature in [K] with same dimensionality as qv.
Note
This variable must be supplied as a
xarray.DataArray
in order to copy the dimension names to the output. Otherwise, default names will be used.meta (
bool
) – Set to False to disable metadata and returnnumpy.ndarray
instead ofxarray.DataArray
. Default is True.
Warning
The input arrays must not contain any missing/fill values or
numpy.nan
values.- Returns:
The relative humidity. If xarray is enabled and the meta parameter is True, then the result will be an
xarray.DataArray
object. Otherwise, the result will be anumpy.ndarray
object with no metadata.- Return type:
