The Weather Show - Low Pressure Australia
It looks like the BBC Weather presenters don't know which way air
rotates around Low Pressure systems in the Southern Hemisphere. Watch the latest Weather Show on the BBC iPlayer around 3:30 mins, and they have Low Pressure over Australia rotating anti-clockwise instead of clockwise. http://www.bbc.co.uk/iplayer/episode...ow_25_12_2011/ Back to school for them this week! |

LOL yes indeed! Grief, I never noticed that! At least they were consistent - everything rotating wrongly in the Southern Hemisphere. -- Graham Davis, Bracknell, Berks.

There is one in the opening titles of a big budget BBC Natural History series that rotates the wrong way. -- Cheers Dave. Nr Garrigill, Cumbria. 421m ASL. |

Tony Pretty well never happens, partly because such a system would leak away across the isobars and there is little mechanism in those latitudes to maintain a pressure change. With a tropical storm or hurricane the balancing force is very largely centrifugal, not geostrophic and such a storm could, I suppose, cross the Equator and still be revolving in the same sense though I don't think it would last very long on "the other side."
