Example 16a: Zonal vector plot

Vector plot of a zonal mean

c = cf.read(f"cfplot_data/vaAMIPlcd_DJF.nc")[0]
c = c.subspace(Y=cf.wi(-60, 60))
c = c.subspace(X=cf.wi(80, 160))
c = c.collapse("T: mean X: mean")

g = cf.read(f"cfplot_data/wapAMIPlcd_DJF.nc")[0]
g = g.subspace(Y=cf.wi(-60, 60))
g = g.subspace(X=cf.wi(80, 160))
g = g.collapse("T: mean X: mean")

v = -1 * g

cfp.vect(
    u=c,
    v=v,
    key_length=[5, 0.05],
    scale=[20, 0.2],
    title="DJF",
    key_location=[0.95, -0.05],
