Description of weather overlays

@idefix37 Hi, is it still there? Maybe it is a bug, I will look at it, but the computation is pretty straightforward.

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 ?
-
@idefix37 We will consider it, but for our user interface it would be better to add 3/5/10 range selector like in rain accumulation.
-
@tz
Totally agree!
I suggest "wind accumulation" to include only 3 and 5 days range.
Inaccuracies beyond day 5, are big.
Even NHC, tracks hurricanes up to day 5.

@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.

@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.
