Vertical wind shear
Vertical wind shear as defined in [Sharman2006] is,
\[\begin{split}\begin{align} S_{v} &= \left| \frac{ \partial \mathbf{u} }{ \partial z } \right| \\ &= \sqrt{ \left| \frac{ \partial u }{ \partial z } \right|^{2} + \left| \frac{ \partial v }{ \partial z } \right| ^{2} } \end{align}\end{split}\]- Parameters:
u_wind (DataArray) – \(u\) wind component
v_wind (DataArray) – \(v\) wind component
geopotential (optional) – Array of geopotential values. If provided, derivative in vertical coordinate will be on altitude (see py:func:altitude_derivative_on_pressure_level instead of on pressure level
is_abs_velocities (optional) – If True, uses absolute velocities. Default is False.
is_vws_squared (optional) – If True, returns square of the wind shear. Default is False.
