speed shear in cloud layer supports clouds moving at same rate and holding
flow between sfc and 0.4 km with speed shear around 20 knots (Straight line
in hodograph shows very limited directional shear, but length indicates some
curvature to hodograph between 0.4km to 3.5km indicates some directional
sheer, but limited speed shear.
@16 knots with 20 degrees of directional shear below cloud base
base to echo top 25 degrees of directional shear with limited speed shear (38
to 48knots) following same range ring.
3km very little speed shear ( 2 to 3 knots)
