Explanation / Answer

Correct answer -- (E) Both B and C

Pulse storm -- A pulse storm is a thunderstorm that produces strong to severe weather in a short period of time. These are Single cell stormswhich typically do not produce severe weather and usually last for 20-30 minutes.The "degree of predictability" is extremely low as forecasters are never quite sure which storm will produce severe weather and from which portion of that storm the severe events will occur.  single cell storms ( a pulse storm) seem quite random in the production of brief severe events such as downbursts, hail, some heavy rainfall, and occasional weak tornadoes.
