Firstly, I must let you know that I'm not Windy's personnel.
So, I can't answer all of your questions.
I don't know Windy's plans for the future.
About sky condition, NOAA uses the following definitions :
Turkish State Meteo. Service uses the following symbols:
(cloud coverage in octas as I interpret them)
My question to you:
What is the usefulness if Windy adds a "mostly sunny" icon?
"Partly cloudy" is not enough?
Do you think that the average reader
can see any difference between the following icons?
@Gkikas-LGPZ yes thank you for your suggrstiond :) it can be seen

Is there a way to show 2 layers at the same time by a ctrl-click on the selected layers? Was interested in showing NO2 and CO2, or radar and satellite, etc. I'm sure that I just made a developer's brain pop :)
Love this app, long time user.
@Gkikas-LGPZ in the windy site could not find the showery and rainy symbols in the icons for example in turkish state meteorological office there are different symbols can you help me to find showery icon the windy

@alip As I see, Turkish meteo.(TSTM) is not using any symbol for "rain".
It calls all rainy situations as "light showers" or "showers".
Windy uses the same symbol for thunderstorms and rain showers.
As a thunderstorm is a "subcategory" of a rain shower (but is stronger)
you can distinguish it by the amount of rain.
@Gkikas-LGPZ Wonder why don't they put a little "Degrees' circle like is normal for a number in degrees?

@ivo Thank you.
Old topic or not,I learned the dust particles and other air masses from it.

I seem to have lost the lightening strike function, am I missing a setting or something?

@EricRaisch Hello, lightnings strikes work. Does the issue still persist?

Wind direction and speed
Hour of 24 hour clock
Can I get all this with one click? It worked yesterday but can,t figure out how to display that data at once with different colored lines of the data

@altabird Hello, you will find this information in detailed forecast. Click on the map and expand the picker.
@korina Good morning, I have a question in relation to the weather icons. I have highlighted the hours from 4pm to 6pm, why do we see the icons "Cloudy with rain or thunder" and in parallel we have 0 mm of precipitation?
Thanks a lot!
This is because the level of rain expected is below the minimum threshold.
In general, below 0.3mm you can hardly notice that it is raining
@yves70 Thanks! I have had the same feeling but the confirm sounds better.
@yves70 I have another question about rain layer.
I read that the rain and thunder layer shows the sum of the precipitation of the last three hours. If I compare the information from the map (red circle) with the sum of precipitation shown in the meteogram (red rectangle) I have no correspondence. The picker indicates 7.4 mm of rain, in contrast the meteogram shows 9.8 mm of rain (sum of precipitation of 9pm, 10pm and 11pm ). Why do we have this disagreement?
I understand that you can be surprised to see those differences although you should not.
There are different elements :
- the figures after the coma have not a lot of meaning so 7.4mm could be easily 8mm and on 9.8mm could be easily 9mm. Of course it could be 7mm and 10mm as well
- what the picker is showing is rain accumulation, this is the equivalent to the data from the map called rain accumulation. The data in the meteogram and data from rain accumulation are both calculated by the model, meaning that by definition you can get different values knowing that on top of this difference, Windy is smoothing the data which will also affect a bit the data.
The conclusion is that you should take that as a nice opportunity to get 2 sets of data for rain accumulation, so in your example you can guess that rain accumulation could be somewhere in the middle so around 8.5mm. It is a bit the same approach as comparing the data from 2 different weather models
@yves70 Thanks for your indications.
I agree with you both on decimal values and the data smoothing by Windy, but the map and meteogram should be calculated with the same model, isn't it? So, the same information calculated with the same model on the same coordinates on the same time step. If this is true, I can't understand why we see this disagreement.
As I said above, data from the meteogram and data from the rain accumulation map, even if they are both coming from the same weather forecast model like ECMWF, they don't come from the same calculation within the model. On top, you have the smoothing effect from the app. Therefore results can be different. This is interesting because if you calculate the same thing by 2 different ways and results are the same, probability is high that the result is correct
