You are more likely to wonder about the choice of an iPad to use navigation. Unfortunately did not have time to respond to every request (retirement is still beyond my horizon), a ticket is required. Almost three years after a similar article (¹), of course now completely obsolete, It was time to redo this issue. (continue…)

By a notification corrected the 23 December 2014 (¹), the NWS (National Weather Service) NOAA has announced a major update of its weather predictions GFS model to be effective in mid-January 2015. Actually, This model is partially available on an experimental basis since early December.
On March Global Forecast System (GFS) is a model of weather forecasts produced by the National Centers for Environmental Prediction (NCEP) dependent of the NWS. Dozens of variables (²) atmospheric and terrain are available through this data set, Since temperatures, winds and precipitation to moisture from the soil and the concentration of atmospheric ozone. The world is covered by the current GFS model with a horizontal resolution 27 km between grid points to 10 day. The horizontal resolution is 70 km for forecasts between one week and two weeks. The GFS model is a coupled model, composed of four distinct models (an atmospheric model, an ocean model, an Earth model, and a sea ice model), who compete together to give an accurate picture of weather conditions. Changes are regularly made to the GFS model to improve the performance and accuracy of forecasts. Gridded data are available for download via the NOMADS servers (National Operational Model Archive and Distribution System) and widely used by application developers in the world.
