I see only one explaination to this...
He considers the entire greyflag picker as a wind vector... ???
You have to read what's inside the picker. For exemple on the pictures above : Wind is blowing FROM the east (E / 90° from north) and windspeed is 36 knots.
Can you see this info in the picker, or it is empty ? If it's empy, it doesn't work properly.
Those clouds are pure beauty.
You made a little mistake with the altitudes (15000 and 20000 km)
:) thanks for all these articles.
Hello,
I know that arome model is available for some areas around the globe in addition to a part of Europe. Are the data source different for those areas? It is possible for Windy to use and display data for these areas ?
Well,
Same case in Slovenia. Hottest ever temp has been recorded for february : 24.1°C on the 28th.
https://t.co/WJJx5Njb07
The same in Hungary... 23.5°C recorded in Sarvar. This is a new record for the country...

And I was thinking... Ok this is happening in Europe.... But...
Tasmania has just experienced 39.7°C on the 2nd of march. All time record...

Poor us !
Buenos dias! No es posible. La única forma de pago es en internet.
La forma más fácil de donar es ir directamente a través de la aplicación Windy:

Gracias y cuidate!
Is that the one also called "morning glory cloud" ?
Nice show observed last week in Slovenia.
Northerly wind pushed up by the Julian Alps. This picture shows the south of the alps.
This is the center of a low pressure system over the Atlantic. Storms centers are quiet places :)
It's actually better than using a jetstream overlay with simple lines in my opinion :)
@Леха24 said in real temperature -45 degrees, the site shows 31 degrees, Krasnoyarsk region Uzhursky district:
Uzhursky
I just looked and read -31 and not 31.
DO you have a more precise location may be ?
+1 : Mean air clear turbulence potential would be a nice feature to add because I think it is interesting for all the community and not only for pilots. To go further, In cloud turbulence is available the same way. I've seen some maps using those GRIBs and I'm sure the result on Windy would be awesome...
I was thinking of Sigmets which are also georeferenced but they ar emore intended to be used by pilots... As WXcycles said, Windy is first a weather app... I don't know about future evolutions!
...Regarding clear air turbulence detection & forecasting...
As far as I know, today we can detect CAT from the ground with MST (mesosphere, stratosphere, troposphere) Radars. However they have a very limited range to detect CAT. Airborne weather radars on planes are not capable of detecting CAT, but only turbulence in rain, dense clouds or ice clouds (which is good because those can be way more dangerous than CAT). Some laser systems are able to detect CAT, but they are still too expensive and need too much power to run. Researchers are still playing with them.
Some atmospheric models can also be used to forecast CAT by using additional parameters, and sometimes by mixing certain model computations, I couldn't tell you how though :) . But the results are still today not satisfactory. This is why the main data used by forecasters to depict CAT on aviation charts are pilot reports, and jet streams positions because they know they are almost always linked with CAT. However, like I said, those charts using the GRIBS can be interesting...
Nice !
Regarding aviation weather, I think that a sigmet layer would be a nice feature to add to Windy, waiting for something more detailed in few years/months, who knows? It doesn't seem "too hard" to implement as a new layer...
https://www.aviationweather.gov/sigmet
I wish I could help with coding and developing such tools... But I was to lazy during the programming and coding courses at school :)
737! So you'll win the air race ;)
I think that windy is great to have access to Metars and Tafs and don't know much about pilot weather app, I'll check it. I have always considered that without forecasters analysis, you could never create a real pilot weather app... I see all existing aviation weather app as gadgets which don't really bring something more useful than having quick access to metars and tafs... But... You're right when you say that Windy could be a great platform to create a great and leading edge tool for general aviation or more.
I can imagine a dedicated menu on windy webpage (simply by using and improving the "airport menu"), with simple entries like "departure OACI", "arrival OACI", "time of departure", "plane speed (no wind)", "intended altitude" and waypoints... Actually, there is an online tool which is awesome to do that:
Look at the sigmet layer and route entry... Very simple.
To be able to use the flight planning features of this app using windy would be amazing (except briefing and filing parts, we don't need that...). That would bring something new to the world thanks to Windy "moving wind particles" + TRUE RADAR DATA and LIGHTNINGS. (skyvector doesn't use real radar data).
To have a great weather tool for aviation, Windy will need to use:
-Radar data (OK)
-Wind data at different altitudes (OK)
-Clouds layers (tops, base, ect, OK)
-OACI airports database (OK)
-OACI Waypoints database (free)
-OACI VFR and IFR charts layers (free)
-Sigmet layer (sigmet messages are free but need ot be coded to be shown on the map)
-A dedicated page/menu with interactive entries to enter a route using OACI info with a desired altitude, and at least airplane speed. (don't know if it's possible on windy as I'm not a developer)
=> you could see the route on Windy map, and switch between determined aviation layers (radar, clouds, sigmets, navigation charts...)
=> A monster feature would be to have the vertical cross section of the flight path, showed on a kind of airgram that Windy already uses.
I'm in a hurry, I don't have much time to give you more details and correct my terrible written english but just look the skyvector thing, it's awesome and a windy version would be just perfect.
Hello!
Do you have some info about Arome model for the locations I showed on the map above? I thought it was the same data source? (caribbean, pacific, tahiti...)
Thx :)
Gabriel
You can also find a good description of layers here:
https://community.windy.com/topic/3361/description-of-weather-overlays
Regarding the "Clouds" layer. Like Idefix said, you have to consider 2 info in the same layer :
Clouds coverage in percent from 0% (sand/gold) to 100% (white) of the sky covered by clouds.
Rain or snow (depending on temperature) accumulation in millimeters for the next 3 hours from the selected time. This varies from 0 mm (no dots) to more than 50 mm (purple/light pink dots).
Hello ! :)
Could you tell us what your main ideas for improvement are ?
Indeed Windy is a great tool to have a quick access to general weather like surface wind, cloud base, temperature... You can also see Jetstreams patterns but I doubt general aviation pilots are interested in jetstream for flight planning... You can also quickly see lows and high pressure systems... With some experience you can locate warm and cold fronts... Of course, notams, taf and metar are accessible with recent tafs which is great ! And I was about to forget the awesome RADAR data !!!!!!!!
As you know however, aviation weather is more than that and it has to be provided in a very professional and standardized way. This involves for instance "significant weather charts", which are always drawn by forecasters on a regular basis after a careful analysis of multiples parameters including pilot reports.
This is why you should never rely on Windy for flight planning or any other app (free or not) that doesn't provide professional charts and data. The best solution for me to fly VFR or IFR on small planes is to rely on the aviation met service of the country I intend to fly. It's 99% of the time free and you get official aviation weather. For that reason, I never use an non official app to get aviation weather forecasts. (Or yes...there are private professional providers like rocket route... Jeppesen... Those are expensive though).
Regarding those charts:
I think Windy uses open data to provide us this awesome automated tool. Data like aviation charts or cold / warm fronts, which are not automatically generated (drawn by someone), cannot be used by windy as far as I know.
See you in the sky !

You mean under the airports displayed with circles when you select "aiport" in the quick menu (lower right corner of the map)? I don't remember such thing.
Otherwise you have to select the appropriate layer "cloud top" in the general menu (right side of the window : more layers) and then click on the map and move the cursor to get the numeric value of clouds tops.
Hello,
What model do they use in Australia? Do you know if it's free to use?
I haven't heard much about "southern" weather models so far.
Hey :)
You mean which model would users use?
