Check higher elevations for a mid-level mesocyclone. Hook Echo: A thin, curving , extension of a very high reflectivity feature indicative of mesocylonic rotation and potentially tornadoes. In the velocity image on the left, Blues/green represent winds moving towards the radar, and reds/yellows indicate winds moving away from the radar. This image shows a reflectivity field containing several hook echoes associated with thunderstorms that occurred in Tennessee and Kentucky on May 18, 1995. Hook Echo, Doppler Radar Stock Photo: 135006099 - … The hook is best observed in the reflectivity field. Download this stock image: Hook Echo, Doppler Radar - HRJ1JB from Alamy's library of millions of high resolution stock photos, illustrations and vectors. The hook echo first was documented by Stout and Huff (1953; Fig. 205 votes, 15 comments. The reflectivity appendage usually is oriented roughly perpendicular to storm motion. Note: Sometimes Hook Echoes form before a low-level mesocyclone is evident on radar. Check higher elevations for a mid-level mesocyclone. Hook echo Original - A Doppler on wheels image of a tornadic thunderstorm near La Grange, Wyoming captured during the VORTEX2 project. This was the "original" tornado signature back before doppler weather radar! There's a lot of guesswork to deciphering the internals of a storm based on a slice through its precip core. Hook Echo - A radar pattern sometimes observed in the southwest quadrant of a tornadic thunderstorm. Appearing like a fishhook turned in toward the east, the hook echo is precipitation aloft around the periphery of a rotating column of air 2-10 miles in diameter. Whereas with velocity you can actually see what kind of rotation (on a broad level) is occuring at that level. For confirmation of the presence of a true Hook Echo, switching to the velocity field may show a low-level mesocyclone. hook echoes and velocity couplets Tornadoes are often located at the center of a hook-shaped echo on the southwest side of thunderstorms. 1) in an Illinois tornado outbreak on 9 April 1953, although van Tassell (1955) is given credit for coining the term. 72.7k members in the weather community.
