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.
Since release Apple iOS 8 early October 2014 the app Iridium Mail & Web application
(which replaced AxcessPoint Mail & Web application
) was no longer able to export an attachment in another application by the function "open in".… ". This fact could no longer use a weather GRIB file received as an attachment from the SailDocs server in any application, mainly Weather4D PRO. It took more than 3 month for two successive updates come correct this problem severely handicapping for client users of Iridium :
[Update 21 November 2014] Version 1.0.6 Finally fixes this bug, but unfortunately adds others including rotating display.
[SHIFT-2 of 6 January 2015] Version 1.0.9 fixes bugs display and delete messages (removing rotation, too strong !).
All boaters that make me the great pleasure to follow this blog have understood , I'm up to this day the advocate of vector charts for navigation on mobile electronics applications. I am expressed in many tickets :
Self-quoted (¹) :
“I have already expressed, and I still say that the raster chart is no longer suited to modern computing devices such as tablets, smartphones and smaller laptops. Display inconvenient, file size too big, no database, difficulty update, etc."
According to the good old adage that only fools don't change opinion, recent technical developments hardware and software, recently added maritime events, led me to reflect on the accuracy of my opinion. Trained in the old school of safety in Glénans Sailing School, the only bias I have to authorize me to express is the safeguarding of human life at sea. This may cause a little "old goatee" for some, but I assume. Hang in there, This is gonna be long. (continue…)
