Cyclone!!!!!


Cyclone sometimes causes in New Zealand!!!! It's a tropical depression which causes in the Indian Ocean and in the South Pacific. "Cyclone" indicates "depression" or "storm" in English. In New Zealand, sometimes it is called a "tropical cyclone" On the other hand, there is a typhoon in Japan like that. Their characteristic is almost the same. If a typhoon goes to the west over 100 degrees of east longitude (Tokei 100° in Japanese), it becomes a cyclone!!! But directions of whirlpool (Uzumaki in Japanese) are opposite. A cyclone in the southern hemisphere is clockwise(Tokei mawari in Japanese), while a typhoon in the nothern hemisphere is anti-clockwise.


A cyclone is given a name such as Ken, Chris or Mike like hurricane in America.

Why Cyclones Are Named?

It's interesting and I think Japanese typoons should be also given names like that.

If the latest cyclone will occur, you can know the movement of it here!




★How to make a cyclone★


1. A steam is made on the hot southern ocean by the strong sunlight.







2. The humid hot air rises high in the sky, and the ascending current(Josho kiryu in Japanese) is made and a cloud appears.








3. A wind gathers from around as swirling, and a cyclone is made and moves as spining.
