Multi-panel NWP display
Would Windy consider looking into developing a multi-panel display of available NWP models within the PC platform.
4 panel (as shown in image) or 2-panel would be appreciated.If option is made available to manually select the NWP --- would be a bonus.
Thoughts?????!

RE: Keyboard shortcuts
Thanks, Ivo.
I did stumble across these shortcuts a little while ago and have found them very useful.
Is it possible to add an additional keyboard shortcut that alternates between the available computer models?
This would be super useful when making quick model comparisons of particular weather features.
Thanks.

RE: Windy launches Satellite layer
@ivo and the team,
Amazing effort and a great addition to the Windy platform.
As this is still in beta (and appears very stable so far), could I add a pitch for a further addition to the satellite layer/windy platform?
Another website that I subscribe to offers model output which can be overlaid on top of satellite images. I find this feature very useful when verifying the model output (location of wind changes/fronts/cloudband etc) -- simple and easy.
See images below as an example...Could you consider incorporating layer overlay functionality within the Windy platform....ie, base satellite image with an overlay option of the available model data (may need an opacity slider bar)?
This feature may also assist the hobby meteorologists within you community in identifying major weather systems like frontal features, upper level weather systems etc.
Otherwise, great work guy/girls.......top of the charts!

RE: Enroute 2D weather cut (similar to Gramet or Meteoblue)
Sounds soooo exciting guys š
Ivo.... name a price, Iām happy to pay a subscription.
Your whole team deserve all the rewards - Windy is a global brand ..... congrats.

RE: Windy launches Route Planner
Another comment that I wanted to add.....
Again with VFR option, and in this case concerning Tstorms:
1/ The RH as a proxy for cloud may not always work for cellular convective situations. I have marked out specific regions where the EC model is indicating a line of TStorms on the Rain/Tstorm layer and the Cloud Top layer.....however the RH display in the Route slice only presents cloud below 6000ft. NB: this is consistent with the RH fields found within the area display when you ascend and descend through the available layers. The cloud top layer shows a distinct line of elevated cloud abv 50k ft and would be best avoided.
NOTE: I read in your comments that you will be attempting to add an IFR option for the upper level fields. Could you include a graphical feature OR a line along the bottom of the cross section highlighting "Cloud Top" values???I would also support upper level isotach lines showing jet streams (80/120/160kt etc) and regions of significant vertical wind shear.
2/ A comment regarding the weather/rainfall along the cross section.....the users need to be aware that the rainfall towers/weather(in this case TS's) are for the previous 3hrs hours from the forecast time. I have highlighted this in top image. Just so the user is not critical of the model output when they see rain/weather at a distance point along the route following a weather system OR think that the weather system providing the precip is some x100km wide.
3/ The cloud base....I'm not a great fan of this field (cloud > SCT) when in the case of these tropical Tstorm situations (see above) the cloud base forecast is >8000-12000ft - which is not the case for this region. I like the addition of the DewPoint spread which as least gives an approximation potential cloud base (1-8 Oktas) -- DewPointSpreadx400ft - and again would be better suited to any VFR pilot.
AND finally.........I can see the benefit of "Relative Wind" vectors from a flight planning perspective. But I would also favour "Absolute Wind" vectors from a forecasting perspective. And the official forecasts are all in Real/Absolute wind directions which would make it easier to evaluate the Windy forecast against other official forecasts.
Thanks for the all the effort.........I look forward to utilising this feature.

RE: Which weather model for Japan should we add next?
@anthony10 ....I agree.
If the option is available, I would like an additional global model (JMA GSM) made accessible for the global community.

Weather picker stops displaying when opening Forecast Meteogram
Since the new interface upgrade - the Weather Picker is removed from the display window (PC) after opening the Location Forecast Meteogram panel.
My preference would be, if it is selected, to retain the Weather Picker flag at all times until deselected.

RE: Windy - 4 panel display
@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: Tracking storms and typhoons
@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.

RE: Addition of ECMWF parameter CAPES to Windy forecast suite
@Suty any chance that the developers would add another ECMWF weather field to the Windy list? CAPES. (acronym for Cape-Shear)

RE: Tracking storms and typhoons
@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.

RE: Windy - 4 panel display
@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 .

RE: GraphCast model?
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

Addition of ECMWF parameter CAPES to Windy forecast suite
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.

RE: Windy 39 is here. Learn how to masterclass new features
@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
