New York Severe Storms




Base scan doppler radar image

Composite Doppler scan. Ignore the rings around the radar. The higher reflectivity values in the squall line reflect that there is a lot of water suspended aloft



Wind velocity, shown in knots. 60knots is about 70mph.

Diamond = mesovortex signature (rotating thunderstorm). These along a squall line edge can produce additional damage. Purple triangle = tornado vortex signature.
Cloud water content

Maximum cloud height. Yes, the one in the head of the squall line is at 57,000ft
