<![CDATA[Wind discrepancies between single model and Wind comparison]]>Hi there,

Since the new version of Windy, there seems to be discrepancies between the wind/wind gusts in individual models and those show in the wind compare view,

For example in Denpasar looking at the EC winds only in Meteogram mode the winds gust to 22 knots at 06Z, 07Z, 08Z, 09Z, 10Z and 11Z.

However in the wind comparison view

The wind gusts to 22 knots in the 09Z, 10Z, 11Z, 12Z, 13Z, 14Z - so there is a 3 hour displacement of the wind gusts.

The same is the case for the GFS - gusts to 12 knots at 10Z, 12Z, 14Z, 15Z, in meteogram view

But 13Z, 15Z, 17Z, 18Z in the wind comparison

Please can you look into this?

Thanks Rick

I will check again late in the evening.

We did many tests, but this one is a bit difficult to handle locally, since the issue is not in every timezone.

What's right? What's wrong? No one knows.

Unusable.

So it varies over the day from inconsistent to consistent.

I'm on the Aland Islands and check data for the Aland Islands as well as Sweden in the Stockholm area.

The local time-zone is UTC+3 (Mariehamn). Since I'm only a few days here, my local system on the laptop still is in UTC+2.

Can you please provide more info about what location you checked, but also the location from where you checked this data?

Thanks you a lot.

I will also check late in the evening, that's when during the last days I saw the huge inconsistencies.

Some moderate 13-17kn (tabulated data) or brisk 21-27kn (map)?

Fix this. Please.

I'm sorry for again for being so blunt: But right now, instead of showing popup messages of all the nice new features in the app you should show a popup, that says that currently due to still unknown circumstances sadly the forecast that Windy provides is simply wrong.

Or how would the Windy team describe the catastrophic discrepancies documented above?

This needs to be fixed right now or you need to inform your customers in a official way of the current deficiencies.

Another example from just right now.

Unusable. Plain wrong.

The last screenshots I made in the late evening.

Right now (10:40 Berlin time), map, arrows and tabulated wind data seem to be in sync (see screenshots below). Maybe this supports debugging.

Right now, we have a new version with smaller features and bug fixes in the testing process, so we will do our best to fix this into this new version.

To be clear: This is no small "flaw" but a major bug.

I'm on a sailing trip at the moment. These inconsistencies make Windy unusable at the moment.

So, please re-prioritize and fix this as soon as possible.

It feels like the wind arrows show the correct values and directions, but the model data in the table below is shifted along the timeline.

When the 12Z EC run dropped in it seemed to be OK but when the 06Z run comes in it seems to cause issues. So we look forward to the next update. Thank you Windy team!
