Animation: Avg profiles of 30 Ivan sondes with low BRCH above cirrus base

Note: Calcs represent a 400m layer avg with values output every 100m.


STAB represents numerator of BRCH calc

ie (G/THETA)*(DTHETA/DZ) *104

VSHR represents denominator of BRCH calc

ie [(DU/DZ)**2 + (DV/DZ)**2] *104

Yellow/magenta shading BRCH < 1 and 0.25
