Title: The Hook Echo
Concept: In the days Before Doppler radar, this echo pattern was an indicator of a possible tornado.
Detail: In the years before Doppler radar, meteorologists warned the public of possible tornadoes based on hook echoes as seen on their scopes. Typically, a severe thunderstorm, with >55 dBZ precipitation at its center, will be moving rapidly northeastward. At the right rear flank, usually the southwestern quadrant, a spiraling pendant or hook-shaped echo will appear. Conventional radar cannot see the actual tornado, but apparently can see the parent tornado cyclone which spawns the smaller tornado. Thus, at the vertex of the well defined hook, there is usually greater than a 75% chance that a funnel or tornado cloud could be spotted. Please note; the tornado hook occurs as much as 10 miles away from the heavy rain and hail. Tornadoes most often occur on the edge of a severe thunderstorm, not deep within its core. Useful as hook echoes are, only about 20% of tornadoes actually produce a hook-like signature on radar. Modern NEXRADs can map the actual tornado cyclone, and even sometimes the tornado vortex winds, greatly improving warning reliability.
