Grib files have become essential for navigation software users. Thanks to them, it is possible to read always more reliable and precise weather forecast on longer time periods. But where are these data coming from? And who are the different providers?<\/em><\/p>\n

What is a GRIB file?<\/em><\/p>\n

It is a numerical file displayed in the form of a geo-localized mesh and incorporating data on the grid intersections. One or several data can be found on each point (wind, waves, rain, pressure, air temperature, current<\/strong>\u2026) displayed in the software navigation<\/strong> in the form of barbules, arrow<\/strong>s or colored areas. The grib<\/strong> incorporates several grids spaced out by a time step defined by the model (between 1h and 12h) in order to see the evolution of the weather forecast on several days.<\/p>\n

Where are these data coming from?<\/em><\/p>\n

Weather forecasts<\/strong> are calculated by computing models which try to assess the most predictable scenario based on the initial situation and the experience of the evolution of these situations in the past.<\/p>\n

This task is made by a lot of weather centers making use of scientific resources and the necessary computing power.<\/p>\n

1.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 The National Oceanic and Atmospheric Administration (NOAA)<\/h2>\n

Certainly being the agency provided with the biggest quantity of global weather data<\/strong>, the NOAA<\/strong> gives access for free to grib files issued from different calculation models.\u00a0<\/span><\/p>\n

GFS model<\/h3>\n

It is the most common and used model. Global weather forecasts are delivered for free by the NOAA.<\/p>\n

AROME model belongs to a new generation: regional models with very fine mesh. Its particularity is to integrate observations coming from satellites and radars and to take into account 250 types of surface (lakes, vegetation, urbanized areas).<\/p>\n

As a result, it provides forecast files integrating the impact of sites effects (sea breeze, effects linked to landscape, thunderstorm\u00a0\u2026<\/strong>). The geographical coverage is very limited and is spread just a little bit beyond the metropolitan France.<\/p>\n

To get gribs\u00a0 about wind, pressure and air temperature data on Meteo France website, it is necessary to select \u201cSP1 \u2013 Param\u00e8tres courants \u00e0 la surface\u201d, then to integrate the grib into the navigation software.<\/p>\n

Be careful, data by default \u2013 \u201cSP3 – Param\u00e8tres additionnels (2) \u00e0 la surface\u201d<\/em> \u2013 are data about humidity and period of sunshine and are not read by ADRENA.<\/p>\n

6.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Predictwind<\/h2>\n

Predictwind uses its own calculation model. Like AROME from Meteo France, Predictwind can integrate local specificities and their impacts on weather forecasts (sites effects or linked to landscape\u2026). Calculations are made from American GFS and Canadian CMC weather data with different levels of precision (60km, 8km and 1km). The initial weather conditions files are entered into the model. The 60km resolution model forecasts are first calculated and edited to create a 5 day forecast. For each 60km*60km region, the model uses many complex equations to calculate all meteorological fields, such as wind, temperature, humidity, pressure, rain<\/strong> and their interaction. This process is then repeated for the 8km model run (for each 8km*8km area) based on the 60km model run. Finally, the finest resolution model (1km) is created from the 8km model run on localized areas. Significant computing resources are required to run the 3 models in this configuration.<\/p>\n

The process is automatically repeated every 12 hours. There is no historical data involved in the calculation. Contrary to other models, PredictWind<\/strong> estimates the most predictable scenario based on the initial situation and without any historical data involved, so that each 12h forecast is independent from the previous one.<\/p>\n
