Personally, I don’t see any problem with the wind angle relative to the isobars when using the HRDPS model.
Over the sea, we can generally observe that the wind forms an angle of 15°/20°. Here, over Hudson Bay, the angle is a little larger.
Over land, it is generally 30°/40°, but it increases if the terrain is more rugged.
In the mountains, especially in the high mountains, this angle can reach 90°, as you can verify with other models over the Rockies. This is what we observe in British Columbia.
These changes in angle relative to the isobars are due to increased friction on the earth's surface.

**The Best Weather App… **
I don’t usually gush over apps. Rarely do I find one that doesn’t have some problem, missing feature, or something that doesn’t make it do what it’s supposed to do. Windy is the exception. When I first purchased a subscription, I thought, “what are you doing?!?!” “There are hundreds of FREE weather apps!” Well, I’m on my second year now, and I have the Windy app front and center on my new iPhone 16 Pro Max. The new Radar+ is a work of art. I love the blue overlay, (or whatever it’s called). This is everything I can imagine ever wanting or needing in a weather app! I can usually call the weather better than our local TV meteorologists! Keep up the stellar work. I look forward to what’s next…

Hi David,
The weather chart shown in the Vendée Globe website is apparently provided by Marine Weather Intelligence MWI
https://marine-weather.com/
This brand new company has been launched by 2 persons, one of them, Christian Dumard, is very well known in France as a routing specialist and a marine meteorologist. In addition he used to provide training on the use of Windy for sailing.
Here is an article from Ouest-France newspaper, explaining how MWI plans to base their technology (translated from French):
“ The MWI Yachting app will be based on the Windy weather forecasting tool, to which routing sheets will be added. "We want it to be as intuitive, fluid and educational as possible," says Basile Rochut, co-founder of the company in Auray. Depending on its analyses and needs, Marine Weather Intelligence will be able to communicate more easily with its customers via a chat. The app will be accessible on the web and will be a paid service. Prices will depend on the services used.”
Did MWI get an agreement with Windy via the API ?
That would explain why wind and waves color scale and particles animation on the Vendée Globe cartography is very similar to Windy design.

What model is used ?
Finally the Vendée Globe organisation does not want to share its data (the position of boats for tracking) with Windy, but Windy shares its weather data with it !

Ferramenta necessária! Obrigado equipe Windy por esse upgrade! Assinei o Premium e recomendo fortemente! Grande abraço!
