Description of weather overlays

@sonnigekerstin I would like to know how to decode the cloud symbols on the meteogram. Most are obvious, however some less so. For example, the four stacked horizontal gray horizontal lines? thanks
-
@edneff
These lines correspond to altitude levels. They allow to know the altitude of the clouds shown on the Meteogram.
-
700h means 700hPa. This altitude is expressed as atmospheric pressure level.
-
3km is the altitude in metric
-
FL100 is used by aviation as flight level. FL100 correspond to 10000ft level.

Hi,
Today there is no similar strange track. I have checked one or two tracks in the North Atlantic. They seem to correspond correctly to the max. gusts predicted in the same area once during the 10 days.
A suggestion: sometime the track is due to a strong wind at day 8 or 9. For people it will be difficult to understand why they see this storm track if the strong winds are forecasted at near the end of the 10 days.
So, instead to show the wind speed in the picker, may be it would be better to show the date when the max. gust is expected ? -
@ivo I am new user of your application . I want to know how to use this application and how to understand the sign. Because I am non technical person.
And also I want to tell you that radar function is not working india -

The ECMWF CAPE and thunderstorm layers are very different - e.g. massively high CAPE over parts of the UK but not much in the rain/thunder or thunderstorms layers. Does anyone know why these are so different? What goes into the the thunderstorm layer?
Thanks

@ekdyer
CAPE is a measure of instability.
However, instablility on it's own is not enough to ensure thunderstorms.
There needs to be a lifting factor due to orography or frontal activity.
Check for other hints such as high humidity and a forecast of showers in the area.

The rain accumulation..that's in inches correct??Not feet* I'm in Louisiana following Barry
-
@ambnmwm
Yes Rain accumulation is in inches, even if you read 3ft on right hand of the scale. -
@ivo what are the meanings and descriptions of meteorological icons used ın meteograms for example which icon is "PARTLY CLOUDY" and the other icons?
-
-
Thank you very much:)
-
@Gkikas-LGPZ thank you:) in addition what are the percantage of clouds in partly clouds and mostly clouds and In Turkey we use "less cloudy"icon in forecast this less cloudy icon is includes in windy pages because ı did not see less cloudy icon
-
@alip
I supose partly cloudy is up to 50% (1~4/8).
For more details you can use the picker.
-
@Gkikas-LGPZ thank i have one more question whick kind of icons are heavy light showers or heavy thundery or light rain for example in Turkey there are light rain and light showery icons in forecasts

@Gkikas-LGPZ thank you very much in addiction is there any formula for calculating wind gust from avarage wind speed and which formula iş used in calculating wind gusts
-
-
@Gkikas-LGPZ thank you:)
-
@Gkikas-LGPZ in addition which model is the best for calculating wind speed gusts avarage wind speed and precipitation amounts used in our site what are your model explanations
