    hi all,just for grins i keep amundsen-scott, antarctica as a favorite on the weather underground weather page. it shows the latitude as 90.0 south.i am curious about directions right at the pole. for example, the wunderground page for amundsen-scott is showing the wind at 5 mph from the nnw. (19-dec-07 15:44 utc)how are directions reckoned at the poleʔjust curious.thanks.

    as youʹve surmised, directions here are a bit weird because every way is north (using the normal way people reckon directions).to get around the problem they use a grid system. take a map of antarctica. orient it so that 0 degrees longitude is pointing ʹupʹ and overlay a grid on the south pole. zero longitude is grid north, 180 degrees is grid south. 90 degrees clockwise from north (90e) is grid east.good questionǃg
