Windy Launches Premium 15-Day Forecast for ECMWF Model using AIFS technology
-
Dear Windy,
I am a premium member, but the ECMWF forecast is still only 10 days on my phone app.
How can I access the 15 day version?
Regards,

Thanks windy … Happy to get this new feature but 15 days AIFS not showing on both iPhone and iPad

Seems the 15 days forecast is not showing on the bottom ruler hence you need to pick a specific location to get the AIFS 15 days. Would be nice to get also the 15 days on the opening screen to get a general overview of a larger area/region. I’m sailing and this would help to assess and take decision on the next passage.
Thanks Windy Team -
Thanks Gavin,

@idefix37 Thanks but still … would be ‘a nice have’
-
AIFS extension to the standard 10 days is displayed in the point forecast table.
Here shown in iPhone in landscape mode

@Polina-Nozdrina Ever since I subscribed to windy, 4 years ago, I've been enjoying it at work. Most of the time it shows correct reports. Keep it up, we need Have fun dear.

15 days ahead plus minus all possibilities we have, that is great to think about specifically to learn a lot about Life on Earth, thank you all ! And by the way the artificial intelligence for support in it.

@Polina-Nozdrina Thanks for this nice new feature :)
However it seems that my phone is not wide enough as the days are not displayed in the top chart which makes it a bit useless. They do appear when I switch to landscape view though. I guess you are aware of this UI issue.

@Polina-Nozdrina
I can't make the payment smoothly. I've never used such a crappy payment system. -
@Victor_windy Hello, could you please provide more info about your device?

@浙江省应急 HI, I see you were successful at the end and your account is a Premium one. Do you still need any help?

Hi @Suty, it's a Samsung Galaxy S20 5G (SM-G981U1)

@gavin-swonnell yeah! Mine too!

Is their any data published on the accuracy of this model for forecasting wind, sun, rain, temperatures out to 15 days?
I find your description of the model contradictory. At the beginning it's touting using this model plan for future activities with more accuracy and at the end it's stating forecasting out 15 days is risky and caution should used for planning activities around it. Would be good to know the positive predictive value when it forecasts a windy day on a certain body of water 15 days out (ie what % of the time that it predicts a windy day does it turn out to be correct) and likewise what is the sensitivity (what percent of windy days does it truly pickup 15 days out).
We recognize predicting weather/wind is challenging but it would be helpful to know if the accuracy is a flip of the coin (50%) or more like 80-90%.
Thanks for all you have done with this great app! -
Greate, Perfect application for an AI.
Will also the current prediction be better with the AI ?
Re. The operation of the AI,- will the AI operate with constantly fintuning or will the AI training be updated as software in general, ie in steps as new releases?
For paragliding on a specific spot many times its possible understand how the local whether usually deviate from the forecasted .
IF the AI take in to account the actual weather at a spot, the local variations at this spot ought to learned by the AI.
Correct?
Then the AI also ought to make better forecasts for that specific spot even in the short and medium term forecast,I usually look the predicted weather for a place and a specific day. I then follow how the prediction changes day by day. Then it's possible to see a trend in how the forecasted weather changes. This give me a hint on how the predicted weather for that day and place is most likely to change if changed at all.
- Is this a valid way of interpret the possible the forcasted weather i.e. the possible changes in weather compared to the predicted original prediction?
Is there any way the see the calculated certainty of presented forecasts?

The addition of AIFS is just an extension of the current ECMWF model with lower resolution

Correct?
Then the AI also ought to make better forecasts for that specific spot even in the short and medium term forecast,For paragliding, in mountain I guess, you can try Meteoblue which includes AI algorithms. This model is better and more accurate in mountains. But it is only available in Basic forecast table, not as a weather map and not in Airgram / Meteogram.

This is not shown in Windy.

First -- thank you developers for integrating this forecast.
Second --
the warnings about how the tail end of these longer forecasts are less reliable has no visual indication on the forecast, nor any way to disable this longer-term, less accurate forecast. That caveat only appears on the announcement of this product.
Likewise, there should be a visual cue that after day ~6 or so, the forecast is not of the same level of accuracy. Perhaps a change in background or hashing to visually cue the less accurate tail end.
EG When NOAA releases its extended hurricane forecasts, you'll notice that the cone gets larger and the central line of the path is disabled by default. This is because there is less certainty.
Personally, I'd rather have a button to turn off this 15-day completely and revert to the old week long forecast. It's hard to read on my iPhone and I know it's less reliable.
Thank you,

@atthenius
Man can’t say that the AIFS extension is less accurate, but it has a lower resolution.
See what ECMWF says about this AI model.
https://www.ecmwf.int/en/newsletter/178/news/aifs-new-ecmwf-forecasting-system
Note that its resolution is now 0.25°, same as GFS.Then there is a clear mark in the point forecast table, but not when you are just looking at the map.
And at the end of the point forecast table you can set the forecast period back without the AIFS extension.
You get only 10 days forecast in the table but also on the map.
By the way I don’t understand why it is said 7 days, or I miss something. -
