Plotting 500‑hPa Geopotential Height, Wind Speed, and Wind Barbs with Python, xarray, and Cartopy

This tutorial shows how to load a NAM NetCDF file with xarray, smooth 500‑hPa geopotential height and wind components, compute wind speed using MetPy, and create a Lambert Conformal map with Cartopy that displays color‑filled wind speed, height contours, and wind barbs, finally saving the figure as an image.
