Forecasts Models

Grouped into a term GFM (Global Forecasting Models) models meteorological and oceanographic forecasting used by Weather’N’Ride have the following characteristics

1 . Weather patterns :

The GFS model

Key features:

global model
Horizontal resolution of 55km
Runs available: 00, 06 , 12 and 18 UTC
No extraction time : 3 hours
Depth: 180 hours
The GFS (Global Forecast System) model is a global model ( global coverage ) , mesh calculation 0.5 degrees (approximately 55km) .

The GFS model is developed by the NCEP (National Centers for Environmental Prediction) , an entity belonging to the NOAA (National Oceanic and Atmospheric Administration).

Weather’N’Ride offers its users the data from the GFS model on the entire planet to a depth of one week, and no time of 3h .

The Weather’N’ride team composed of specialists in meteorology and oceanography, made ​​very precise algorithms for associating symbols representing significant time each time , performing operations on a large number of meteorological variables at different altitudes .

 

The HDAM 9km model

Key features:

Model area Europe
Horizontal resolution of 9km
Runs available: 00, 06 , 12 and 18 UTC
No extraction time : 1 hour
Depth: 96h
The model 9km HDAM (High Definition Atmospheric Model) is a non- hydrostatic model developed by Extens3C ( France ) from a core model WRF ( Weather Research and Forecasting ) , in its version of ARW (Advanced Research WRF ) .

9km HDAM is a model with choices under specific mesh parameterization , and particularly effective .

The horizontal resolution of 9km can treat an area “Europe” , in record time , making the best computing capacity of Intel processors.

The HDAM model is available to users free Weather’N’Ride for the most recent run, and with time optimized calculation.

The only completely free solution on the market , with these features !

 

2 . Sea state models:

The NWW3 model multi -grid NCEP

Key features:

Model global zone, between 77 ° N and 77 ° S
Horizontal Resolution: 0.5 °
Runs available: 00, 06 , 12 and 18 UTC
No extraction time : 3 hours
Depth: 180h
Weather’N’Ride uses NWW3du NCEP (National Centers for Environmental Prediction) , belonging to the NOAA (National Oceanic and Atmospheric Administration) is a global organization model , resolution 0.5 ° (approximately 55km) , based on the WaveWatchIII code.

NWW3 is forced by wind fields from the GFS model , and provides data per time step 3h , to a depth of 180 hours between 77 ° N and 77 ° S.

Mesh calculation NWW3 model is 0.5 ° for depths greater than 25m .

NWW3 is not available on the enclosed or semi -enclosed seas ( Mediterranean , Caspian Sea , Persian Gulf , Red Sea … )

 

3 . Models for predicting tides

Depending on the geographical location of spots ( or world area France area ), data on the state of the tides were defined using the following sources:

Zone France :

Tidal signals have been generated By MetOcean Solutions Limited, using the tidal harmonic constituent atlas produced as a part of the PREVIMER project (www.previmer.org) coordinated jointly by the SHOM ( Hydrographic and Oceanographic Service of the Navy ) and IFREMER (Institut French search for exploration of the Sea ) . The domain ‘MANGA’ covering the Channel and Bay of Biscay regions with a resolution of 700m was used. (see Pineau-Guillou Lucia, 2013 and PREVIMER, 2013 for further informations about the model domains and validations )
