Stretching Deformation#

Use metpy.calc.stretching_deformation.

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

Stretching 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 stretching deformation of the flow
str_def = mpcalc.stretching_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, ds.lat, str_def * 1e5, range(-80, 81, 1), cmap=plt.cm.PuOr_r)
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('Stretching Deformation Calculation')

plt.show()
