Wind Speed#

Use metpy.calc.wind_speed.

This example demonstrates the calculation of wind speed using the example xarray Dataset and plotting using Matplotlib.

Wind Speed Calculation
import matplotlib.pyplot as plt

import metpy.calc as mpcalc
from metpy.cbook import example_data

# load example data
ds = example_data()

# Calculate the total deformation of the flow
wind_speed = mpcalc.wind_speed(ds.uwind, ds.vwind)

# start figure and set axis
fig, ax = plt.subplots(figsize=(5, 5))

# plot wind speed
cf = ax.contourf(ds.lon, ds.lat, wind_speed, range(5, 80, 5), cmap=plt.cm.BuPu)
plt.colorbar(cf, pad=0, aspect=50)
ax.barbs(ds.lon.values, ds.lat.values, ds.uwind, ds.vwind, color='black', length=5, alpha=0.5)
ax.set(xlim=(260, 270), ylim=(30, 40))
ax.set_title('Wind Speed Calculation')

plt.show()
