Question

What are the three kinds of thunderstorms? Explain each in one or two sentences.

How is RADAR useful in determining whether or not a thunderstorm might produce a tornado?

Answer 1

Actually there are 4 kinds of thunderstorm,

1) Single cell thunderstorm= here the updraft and downdraft are not severe. So here the threat is less or slight threat will be there.

2) Multicell cluster= here the updraft and downdraft are moderate. So here the threat is low to moderate.

3) Multicell lines= Here the updraft and downdraft is moderate like Multicell cluster and also the threat is moderate.

4) Supercell= Very strong updraft and downdraft condition. Very strong and severe weather.

2) From the colour of radar we can determine whether thunderstorm might produce a tornado or not. Tornado is a rotating wind associated with low pressure. They both have vertical movement, that's why detecting them is a tricky thing. But the colour of radar tell us the story. The brighter colour suggests higher velocity or speed of wind whereas darker colour shows a low velocity wind. If in the radar we can see the brighter colour winds rotating then we can expect there will be a tornado situation. Without strong wind and rotation tornadoes cannot occur.
