Do you know the keywords in hurricane, and tornado?

Answer 1

I am a little confused by what you mean by keywords in ....? Both phenomena are associated with cyclonic (counterclockwise) motion. The hurricane is most destructive because of the storm surge associated with it while the tornado is most destructive because of its winds. These two events occur on vastly different time and spatial scales. While a hurricane may last 10 days or more and cover many thousands of miles along its track, the tornado lasts generally less than an hour and has a very short track. The hurricane covers many thousands of square miles while the tornado covers a very limited area on the order of less than a thousand feet. While these may not be the keywords you were looking for I believe they do touch on the key differences.

Answer 2

I disagree with two points in your answer. Cyclonic circulation is anticlockwise in the northern hemisphere but clockwise in the southern hemisphere. We get hurricanes and tornadoes here too. While the storm surge associated with hurricanes can be devastating, so are the winds. Tropical Cyclone "Tracy" , a cat 4 system, destroyed Darwin in 1974 with winds alone.
