absolute_vorticity
(u, v, dx, dy, lats, dim_order='yx')[source]¶ Calculate the absolute vorticity of the horizontal wind.
Parameters: - u ((M, N) ndarray) – x component of the wind
- v ((M, N) ndarray) – y component of the wind
- dx (float or ndarray) – The grid spacing(s) in the x-direction. If an array, there should be one item less than the size of u along the applicable axis.
- dy (float or ndarray) – The grid spacing(s) in the y-direction. If an array, there should be one item less than the size of u along the applicable axis.
- lats ((M, N) ndarray) – latitudes of the wind data
Returns: (M, N) ndarray – absolute vorticity
Notes
If inputs have more than two dimensions, they are assumed to have either leading dimensions of (x, y) or trailing dimensions of (y, x), depending on the value of
