@peterh337 there is EC model data within the MeteoBlue model list (not as many fields compared to Windy) but it also has ICON (worthy challenger) along with others. For my area of interest, the Australian region...this is available

My preference is Windy over MeteoBlue whilst working, however, I can't efficiently navigate around the current Windy UI. MeteoBlue offers an alternate site that has added features that I view as beneficial for the cost.

I have also wondered about the EC model's forecast resolution available to Windy for use within a public site. I know of another site that provides non-restricted access to EC data but at a resolution of 25km. The good stuff at 9km I would believe is available to paying customers (and is not cheap). I haven't asked but is Windy using 25km or 9km EC data?

On A PC (in my case Windows OS), the keys "page up" and "page down" will allow you to ascend or descend through the vertical levels. I don't use the slider, I use the keyboard to skip through the levels.

@B-Low

Have been a Windy user for a long, long time, and as of next week my subscription runs out (not to be renewed). I spent my $'s on MeteoBlue. Not as smooth as the previous version of Windy but there are many other nice model/display features available for subscribers. It costs a bit more than Windy but I am happy to pay and try for now in the hope that maybe Windy will sort this mess of a UI out in the not-too-distant future (or maybe they'll take a few more bruises for now and stick to their vision with this new UI).

This is what I am looking at now on my laptop for the same pinned icons before the UI change.....

So now I have to commit to memory which combination/pattern of colors each icon represents as a forecast field.

At least do us the courtesy of making the icons more distinguishable or recognisable to the weather field it is representing.

It is a very pretty but meaningless array of icons.

I reckon this is my final rant ..... you have served me well in the past Windy, onto new pastures.

@Suty @Korina

Can someone provide the reasoning/advantages please with the change to the forecast parameter structure????

Where is the benefit of using symbols as opposed to the previous listing structure which had the "advanced feature" where I could tailor which elements I wanted access to?

DO NOT LIKE the new format........

@Filip_K thank you

@Suty

Are the meteogram images generated in-house or are they sourced through ECMWF or another party? If in-house, are you able to seek which ECMWF gust field code is used for the Meteogram display?

From the ECMWF HiRes 10-day dataset:
10fg6 (10m gust in last 6hrs),
10g (10m gust in since previous post-processing),
10fg3 (10m gust in last 3hrs),
and i10g (instantaneous 10m gust).

There are a few options available. I use the EC gust as a forecasting parameter and would like to get confirmation as to the gust sampling time.

Thanks.

Windy team developers, can you provide the 10m wind gust field used in the meteogram window for the ECMWF model? Is it 1/ instantaneous wind gusts, 2/ 10m wind gusts in the last 3 hrs, or 3/ 10m wind gusts in the last 6hrs?

Looking at the above example, the wind speed and gust speed at say 12pm onwards (through the afternoon) is not sensible. 4-7km/h mean wind speed and 20-35km/hr gust speeds. And I am familiar with this location and likely winds.

Would I be correct in saying the wind gust forecast is taken over the previous 6hrs, maybe 3hrs?

Thanks.

@idefix37 @AlexVídeos alex

you can get more creative with the color palette and add narrow bands of color as a proxy line to highlight a threshold value - in the above image 'gale force winds'.

@kkorona here is a nice example of what I was describing above with a possible TC developing off the NW coast of Australia later in the week. The forecast pointer shows 71kt (gusts) and highlights continual TC development before curvature to the right and weakening. Then the system proceeds to redevelop as it straight lines it towards the Indian Ocean. The path and intensity of forecast gust wind speeds are clearly shown over 10 days. The pressure pattern is for ECMWF TUE 19th at 12Z.

@Suty any chance that the developers would add another ECMWF weather field to the Windy list? CAPES. (acronym for Cape-Shear)

@kkorona If you want to show the track and intensification/decay of a tropical system (such as a tropical cyclone, TC), I use the "wind accumulation" layer and set it to whichever the available forecast period you desire (Next 24hrs/3 days/5 days/10 days). This shows you a continuous accumulation of wind gust speed for the targeted system. Firstly, set the forecast day/time for when you want to see the position of the system re MSLP. As there are no TC's anywhere around the globe, I'll use the deep low east of Japan.
Current position

Forecast position in 9 days time

And accumulation of gust speed (selecting "wind Accumulation") set to "Next 10 days"

==>> path of strongest winds shown as "purple" in this example. Following the wind scale, you can see on one panel where the system changes intensity and the path of strongest winds (and to avoid if sailing).

Hopes this assists you with your sailing adventures.

@stitch or even a 2-panel side-by-side aspect with the freedom to select independent weather parameters at concurrent time steps.

AND also unlocking the time step sync to maybe give the option of selecting a time-step difference between the two panels (say 6-/12-/24 hour time step....or whatever) allowing for analysis of changes in forecast parameter over a set time step which can then be locked in time sync.

Because, at the moment, the Windy platform doesn't have the option to skip +/- 24hours with a single keyboard/mouse click (that I know of). Just seeking to improve what is already a very useful forecasting platform .

@stitch added images The four independent Windy panels would provide the freedom to setup each panel (like we all normally do now) but with the additional feature of adding variation across the four panels for easy side-by-side comparison.

An additional concept - could the time (scroll bar) have the following options:

linked together at the same time for all panels, and
include a staggered time interval (optional) between each panel (say, 24hr interval) and then linked/locked with that set time interval retained for advancing along the time bar?

Re: Multi-panel NWP display

@SUTY @Korina .....any further thoughts on implementing this display concept into a future Windy upgrade???

@Wheats I would guess "fog clearing".

Graphcast looks exciting and verification stats appear to support an increase in forecast accuracy out to 10 days in comparison to EC HRES. However, you might be a little disappointed with the current Graphcast resolution should Windy support implementing this model into the current model suite. Res EC HRES ~9km GRAPHCAST ~30km

Can I draw your attention to a weather parameter CAPES (combination of CAPE and SHEAR) available in the ECMWF dataset for determining conditions favourable for development of severe weather, namely severe thunderstorms.

https://codes.ecmwf.int/grib/param-db/228044

From ECMWF.- "High values of this parameter indicate where deep, organised convection is more likely to occur, if it is initiated.
This parameter is the product of wind shear and the square root of convective available potential energy (CAPE). The wind shear denotes bulk shear which is a vector difference of winds at two different heights in the atmosphere (925 hPa and 500 hPa). The square root of CAPE is proportional to the maximum vertical velocity in convective updraughts."

I have used this parameter as an operational meteorologist and have seen the benefits. I view this as a very useful addition to the Windy platform.

@FrancesW this is the best site I know for historical Sounding Data http://weather.uwyo.edu/upperair/sounding.html It is outside the Windy App and takes a few steps to set-up the data request

@Korina

For the Australian region, my order of preference is ECMWF then AccessG.

I use the "Compare Table" and "Wind Meteogram" regularly as a poor man's ensemble forecast tool for point locations.

Keep up the good work :)
