Is it ture that tornadoes rarely occur in conjunction with tropical cyclones?

Answer 1

Yes.

However, there's an issue of terminology here...

A Cyclone is a tropical Australian event in that they happen north of a line approximately located to the north of Coff's Harbour on the mid north coast of New South Wales. There's a similar southern limit in West Australia, located about Geraldton. We do not get tornadoes in Australia.

The same weather system in Asia is called a Typhoon and the typhoon is not associated with tornadoes.

In the US it's called a Hurricane. That's where you get tornadoes, which are really miniature versions of a hurricane as far as I'm aware.

Answer 2

Being that my definition of tropical cyclone is a hurricane then the answer is false. Tornadoes are highly associated with hurricanes. In fact, I saw the other day that one hurricane was responsible for spawning over 100 tornadoes.

Of course, this is only during the time after it has made landfall. In the ocean, who would be there to see the tornadoes?
