A “hook echo” describes a pattern in radar reflectivity images that looks like a hook extending from the radar echo, usually in the right-rear part of the storm (relative to the motion of the storm). A hook is often associated with a mesocyclone and indicates favorable conditions for tornado formation.
Q. What is the difference between radar and Doppler radar?
How is Doppler different from conventional radar? Conventional radar detects the presence of dense objects (such as precipitation) in the field, while the Doppler system detects a phase shift between the outgoing and incoming signals.

Q. What does a tornado look like on Doppler radar?
Meteorologists look for low CC values within a tornado’s debris ball surrounded by higher values. This often appears as a small blue circle within a larger red area. If the radar shows a strong area of rotation and a debris ball in the same area, it is a strong signature that there is a tornado occurring.
Q. Where is the safest place in your home during a tornado?
Go to the basement or an inside room without windows on the lowest floor (bathroom, closet, center hallway). If possible, avoid sheltering in a room with windows. For added protection get under something sturdy (a heavy table or workbench).
Q. Can you survive a tornado in a ditch?
If there is no shelter nearby, lie flat in the nearest ditch, ravine, or culvert and shield your head with your hands. If you live in a tornado-prone area, encourage your mobile home community to build a tornado shelter. The least desirable place to be during a tornado is in a motor vehicle.
Q. Will my phone alert me if there is a tornado?
The alerts are proven life-savers. Just recently, eight people in southern Georgia sought shelter after their cell phones alerted them to an approaching tornado. If you have an Android device, look for the “emergency alerts” option in the settings of your phone’s default text messaging app.
Q. What is the best tornado warning app?
11 Best Tornado Alert Apps (Android & iOS)

Q. How do I know if a tornado is coming at night?
Day or night – Loud, continuous roar or rumble, which doesn’t fade in a few seconds like thunder. Night – Small, bright, blue-green to white flashes at ground level near a thunderstorm (as opposed to silvery lightning up in the clouds). These mean power lines are being snapped by very strong wind, maybe a tornado.
