Hello,
I found an interesting graphic tool to browse the world weather
forecasts for the next 6 days. Over a world map "google" style you can
display many layers : the surface pressure, the clouds, the rain and
the winds at 1000, 800, 600, 400, 200 and 10 mb. The precision is 1
geographic degree ... and this is free :
