'm told that in the Southern hemisphere cyclones are Low pressure and go anticlockwise, the opposite being true for anticyclones in the SH, and the reverse in the Northern hemisphere. In some text on the internet it says that you can tell by looking at the cyclone if you are in the Northern hemisphere. How does that work?
