Code to Reproduce

from metpy.calc import storm_relative_helicity, wind_components
from metpy.units import units
# set needed values of pressure, height, wind direction/speed
p = [1000, 925, 850, 700, 500, 400] * units.hPa
h = [250, 700, 1500, 3100, 5720, 7120] * units.meters
wdir = [165, 180, 190, 210, 220, 250] * units.degree
sped = [5, 15, 20, 30, 50, 60] * units.knots
# compute wind components
u, v = wind_components(sped, wdir)
# compute SRH with a storm vector
storm_relative_helicity(h, u, v, depth=1 * units.km,
                        storm_u=7 * units('m/s'), storm_v=7 * units('m/s'))
