shearing_stretching_deformation¶

metpy.calc.shearing_stretching_deformation(u, v, dx, dy)[source]¶

Calculate the horizontal shearing and stretching deformation 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) – The grid spacing in the x-direction
dy (float) – The grid spacing in the y-direction
dim_order (str or None, optional) – The ordering of dimensions in passed in arrays. Can be one of None, 'xy', or 'yx'. 'xy' indicates that the dimension corresponding to x is the leading dimension, followed by y. 'yx' indicates that x is the last dimension, preceded by y. None indicates that the default ordering should be assumed, which changed in version 0.7 from ‘xy’ to ‘yx’. Can only be passed as a keyword argument, i.e. func(…, dim_order=’xy’).

Returns:

shearing, strectching (tuple of (M, N) ndarrays) – The horizontal shearing and stretching deformation, respectively
