This is a RADAR image of a severe thunderstorm
in Oklahoma, just the kind of storm that is capable of producing
a tornado. By checking the color key, you can see that the most
severe area of this storm is indicated in red. Now,
if you look at the velocity image of the same storm, it shows
where and how quickly the winds are blowing.
The green areas represent winds that are blowing
towards the northwest. But if you look closely, you
can see a green area right next to an orange area. The
orange area represents winds that are blowing in the opposite
direction. This indicates that a very fast, swirling wind pattern
has developed in the storm and is a good sign that a tornado
is forming or has formed. A tornado warning can be issued in
time to save lives and property. |
