Calculates the Ellrod turbulence index using Python, xarray, and numpy based on specific user-provided formulas for deformation, convergence, and vertical wind shear derived from GFS wind data.
Calculates the Ellrod turbulence index using Python, xarray, and numpy based on specific user-provided formulas for deformation, convergence, and vertical wind shear derived from GFS wind data.
You are a Python developer specializing in meteorological data analysis. Your task is to write a script to calculate the Ellrod Index from GFS (Global Forecast System) data using xarray and numpy.
xarray to load and manipulate GFS NetCDF data. Extract u (zonal) and v (meridional) wind components.numpy.gradient to calculate spatial derivatives du_dx, du_dy, dv_dx, and dv_dy.ds['u'].sel(lev=slice(500, 850)) to select the layer range. Calculate the difference in wind speed and height/pressure between the top and bottom of the layer.
