      Hi, I wanted to ask if Windy can add the synoptic compose, like the map of Meteociel, because in this way we can see directly in Windy also the synoptic, and because Windy is more fluid than Meteociel a lot of people can be attract by this. The second thing that I wanted to ask is if windy can add the base reflecitivity forecast, like Meteorologix, because when we see a meteorologic perturbation on the synoptic map or a synoptic compose for the storm, there is the Base Reflecitvity for the confirm. Can Windy add this two things? In this way, Windy can become more useful to make weather forecast.

        Could you post a screenshot of what you call the “synoptic compose” of Meteociel ?

        A simulated radar reflectivity layer has been requested by two users since 2018:

            @idefix37 like this map (https://www.meteociel.fr/modeles/gfse_cartes.php)

              This map is displaying the 500 hPa geopotential heights as a color shaded layer combined with isobars.
              I requested this type of map several time for instance in this post
              https://community.windy.com/topic/40911/summer-in-the-city-heatwaves-in-urban-areas-their-impacts-and-future-challenges/3?_=1784270263349
              Geopotential heights are only available as isolines in Windy.

                A map identical to the one on Meteociel is available on Meteoblue.

                  This is an enhancement request to the original post (OP).


                  Composite synoptic chart

                  My favorite composite synoptic chart is the chart on the left on the webpage

                  https://www.wetter3.de/vertikal_en.html

                  This map - based on GFS data - combines multiple atmospheric layers and parameters into a single synoptic overview. It allows to identify large-scale weather patterns, fronts, air masses, precipitation types, and weather developments at a glance.

                  500 hPa Geopotential Height
                  Black contour lines. Show the height of the 500 hPa pressure surface. Used to identify troughs (cold, unstable) and ridges (warm, stable).

                  Surface Pressure (Isobars)
                  White contour lines. Shows low-pressure systems ("T") and high-pressure systems ("H").

                  850 hPa Temperature
                  Yellow contour lines. Show temperature at roughly 1.5 km altitude. Important for air-mass analysis, snow line estimation, and front detection.

                  700 hPa Relative Humidity
                  Gray shading. Indicates moisture in mid-level atmospheric layers. Highlights cloud fields, lifted air, and precipitation potential.

                  Precipitation Form
                  "0" -> Liquid. Rain or freezing rain. Typical of warm air masses, warm fronts, and stratiform rain.
                  "+" -> Solid. Snow or graupel. Typical of cold air masses, winter showers, or higher elevations.

                  Precipitation Intensity
                  Symbol size indicates intensity (starting around 0.03 mm/h). Large symbols -> heavy precipitation / convective cells.

                  Precipitation Type: Stratiform vs. Convective
                  Green -> Stratiform (large-scale). Fronts, widespread lifting. Long-lasting rain, widespread snowfall
                  Red -> Convective (showery/thundery). Vertical updrafts, instability. Showers, thunderstorms, localized heavy rain, graupel

                  See also the legend in german language ( https://www.wetter3.de/hilfe_vertikal_dt.html ).

                  Feature request 1:

                  Recreate this chart in the Windy app.

                  Reason:

                  • The map enables a full synoptic diagnosis and interpretation in a single chart.
                  • There is nothing comparable in the Windy app.
                  • (On the website https://www.wetter3.de/vertikal_en.html it is only available for Europe.)

                  Vertical cross-section diagnosis

                  On the right side of the webpage
                  https://www.wetter3.de/vertikal_en.html
                  the vertical cross-section for the latitude or longitude selected on the left is displayed.

                  Example: Select the "10E" box on the left (LON 10°E: Tunis -> Kassel -> Trondheim).

                  In the vertical cross-section on the right, the contours of the Alps are visible between 45°N and approx. 50°N.
                  This clearly illustrates, for instance, the impact of mountain ranges on weather parameters.

                  You can choose from five different sets of composite weather parameter combinations for the vertical cross-section.
                  These visualizations of composite weather parameter sets are excellent; they make it very easy to understand, for example, why specific weather parameters take on certain values at specific locations based on elevation and terrain profiles.

                  The Windy app also features vertical cross-sections. They are somewhat hidden under the "Distance & route plan" button.
                  Unfortunately, the Windy app currently only allows you to view forecasts for: Car/hike, Boat, VFR, IFR, and Airgram.

                  Feature request 2:

                  Please add one or more of these composite weather parameter sets to the Windy app alongside the existing tabs (Car/hike, Boat, VFR, IFR, Airgram) under the "Distance & route plan" button.

                    No need to add another tab. Airgram already corresponds to the cross-section, as forecast by the weather model. The terrain profile could be added as it is available in the Car/hike setting.
