tangential_component

metpy.calc.tangential_component(data_x, data_y, index='index')

Obtain the tangential component of a cross-section of a vector field.

Parameters:

• data_x (xarray.DataArray) – The input DataArray of the x-component (in terms of data projection) of the vector field

• data_y (xarray.DataArray) – The input DataArray of the y-component (in terms of data projection) of the vector field

• index (str or int, optional) – Denotes the index coordinate of the cross-section, defaults to ‘index’ as set by metpy.interpolate.cross_section

Returns:

component_tangential (xarray.DataArray) – Component of the vector field in the tangential directions

Notes

The coordinates of data_x and data_y must match.
