I mean they don't name tornadoes, blizzards, or tsunami's hmmmmm
Primarily to identify them I guess. There are usually more than one hurricane going about (Hurricanes Gordon and Isaac at the moment) so it makes it easier, mainly for news channels, to talk about each one as if it has an identity rather than 'that hurricane over there'. I think some of the names they come up with are quite funny xD.
I think because they can Renember how much damage that hurcaine did. They put tornados on a scale from 1-5, I don't know if they do the same with hurcaines, but what I think is how much damage it did and so they can reference back to it.
Hope this helps!
you get different levels of hurricanes but each hurricane has different patterns of movement or locations so naming it would just be a reference thing or an identifier so they know what it will do and where it will go. (THEORY)
Hurricanes are catigorised to, just some info for ya :-)
in case you want to chat to it.. its more respectful
