Our Weather Routing uses the Highest Resolution models available for your race area.
PWG 1km Resolution
PWE 1km Resolution
AROME 1.3km Resolution
UKMO 2km Resolution
NAM 5km Resolution
Europe/UK area
If in Europe/UK and racing where the AROME model and UKMO model are available.
For example the Fastnet Race or Middle Sea Race.
This is how we do it.
ECMWF Weather Route,
How the weather routing uses the models for the ECMWF route.
If your route is inside an area where the AROME model is available, the AROME 1.3km high-resolution model will be used to calculate the first two days of the route; then, the ECWMF 9km model is used for days 2-10. Any route extending past 10 days will be completed using the ECMWF ensemble (from 10 days to 30 days).
If your route is outside an area where the AROME model is available, the ECWMF 9km model is used for days 1-10. Any route extending past 10 days will be completed using the ECMWF ensemble (from 10 days to 30 days).
UKMO Weather Route,
How the weather routing uses the models for the UKMO route.
If your route is inside an area where the UKMO 2K model is available, the UKMO 2km high-resolution model will be used to calculate the first 5 days of the route; then, the UKMO 15 km model is used for days 5-7. Days 7-10 will use ECMWF 9km data. Any route extending past 10 days will be completed using the ECMWF ensemble (from 10 days to 30 days).
If your route is outside an area where the UKMO 2K model is available, the UKMO 15 km model is used for days 1-7. Days 7-10 will use ECMWF 9km data. Any route extending past 10 days will be completed using the ECMWF ensemble (from 10 days to 30 days).
PWE and PWG Weather Routes,
How the weather routing uses the models for the PWE and PWG routes.
If your route is inside an area where 1km high-resolution PWE and PWG models are available, this data will be used for the first 36 hours; then, the 8km data will be used out to day 7. From days 7 -10, the PWG 50 km data will be used. Any route extending past 10 days will be completed using the ECMWF ensemble (from 10 days to 30 days).
If your route is outside an area of 1km/ 8km high-resolution PWE and PWG forecast area, the 50km PWE and PWG forecast will be used to calculate the route to day 10. Any route extending past 10 days will be completed using the ECMWF ensemble (from 10 days to 30 days)
USA racing area,
GFS Weather Route, Uses the High Resolution NAM model
How the weather routing uses the models for the GFS route.
If your route is inside an area where the NAM model is available, the NAM 5km high-resolution model will be used to calculate the first 3.5 days of the route; then, the GFS 25 km model is used for days 2-10. Any route extending past 10 days will be completed using the ECMWF ensemble (from 10 days to 30 days).
If your route is outside an area where the NAM model is available, the GFS 25 km model is used for days 1-10. Any route extending past ten days will be completed using the ECMWF ensemble (from 10 days to 30 days).
PWE and PWG Weather Routes,
How the weather routing uses the models for the PWE and PWG routes.
If your route is inside an area where 1km high-resolution PWE and PWG models are available, this data will be used for the first 36 hours; then, the 8km data will be used out to day 7. From days 7 -10, the PWG 50 km data will be used. Any route extending past 10 days will be completed using the ECMWF ensemble (from 10 days to 30 days).
If your route is outside an area of 1km/ 8km high-resolution PWE and PWG forecast area, the 50km PWE and PWG forecast will be used to calculate the route to day 10. Any route extending past 10 days will be completed using the ECMWF ensemble (from 10 days to 30 days)
The Weather Routing data set after running a weather route is best viewed under WIND tables, this shows all the high resolution data, looking at the GRIB or Wind Map provides a general synoptic view of the wind pattern.
