How to read Meteogram

Jary_Geers

Hi!
I'm new in this community.
I also need to know about it,
Thanks.

@Yves70 Would it be better to use 'Fraction of cloud cover' instead of 'Relative humidity'?
Like the difference between Figure 2 (rh) and Figure 3 (cc).

Thank you. This is a very useful guide for a beginner.

@chzhh
It depends but both infos are of course very useful. As ypu can clearly see in both graphs, there is, fortunately, a correlation ! RH has the advantage to be easyly available and largely used

Could someone explain to me the meaning of the shaded colors in both the wind speed line and the cloud base line, please?

@gbrogden
Stronger winds and lower cloud base are color shaded.

When I see 0.1 cm rain and 10 cm of snow in the same meteogram forecast, does this mean both types of precipitation are predicted, or that there’s an equivalent of 0.1 cm liquid in the 10 cm snow predicted, (but all of it is expected to fall as snow?)

@capitancrespo
Rain is shown in mm and snow in cm.
When figures with both units are shown together that means that a proportion of rain is mixed with snow, giving wet snow.

Here convective rain in purple and in mm, mixed with snow in light blue and in cm (shown CM)

Hello,

Using Windy on a Macbook Pro at home for long range weather forecasting. Great.
Once on the Airfield, I only have an iPad mini 4 to hand and the meteogram is very tiny - have I missed a shortcut how to get it to full screen size, or does some extra coding need to be done to offer that capability.
Great App. ✔︎

@ozfrog Unfortunately, it is a limitation of mobile device apps. However, I can forward the request to colleagues for consideration.

@chzhh It seeems more useful.Can you tell me how to make Figure.2?

@先生-陈 Hello, this is the product of China Meteorological Service Intranet. Maybe you can try to make it using Python or GrADS:-)

Can you please clarify the bell symbols (circled)? I assume they represent some type of alert, just not sure if it’s wind, ice, or what. Thank you!

@DogMomster
Yes, these bells mean there is an alert for that location because the conditions YOU set, have been met.
So you should know if it is wind, rain, temperature … we can’t.
Check your Alert.
