Total Deformation#

Use metpy.calc.total_deformation.

This example demonstrates the calculation of total deformation using the example xarray Dataset and plotting using Matplotlib.

Total Deformation 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
total_def = mpcalc.total_deformation(ds.uwind, ds.vwind)

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

# plot stretching deformation and scale by 1e5
cf = ax.contourf(ds.lon,, total_def * 1e5, range(-80, 81, 1),
plt.colorbar(cf, pad=0, aspect=50)
ax.barbs(ds.lon.values,, ds.uwind, ds.vwind, color='black', length=5, alpha=0.5)
ax.set(xlim=(260, 270), ylim=(30, 40))
ax.set_title('Total Deformation Calculation')
