GRIB means Grid In Binary, a format developed by World Meteorological Organization to enable data exchange
across the borders of different national Computer systems. Meanwhile you find homepages offering GFS-Daten (Global Forecast System) in Grib-Format for Download.
Sooner or later every navigation software will display GRIB information as well - most of them already do. Meantime UGrib is software you should have installed on your laptop.
When I last tried the download only worked with Microsoft Internet Explorer....I hope this get´s fixed soon.
