How to read Meteogram
-
@korina Thanks! So the value in Meteogram is the precipitation accumulated over a quite different time period compared to the Rain & Thunder layer? What's the time period you'd applied to do the calculation?
And I'd like to know whether the value of 'rain' in Meteogram & Airgram represents the large-scale precipitation or not? According to the description of parameter on ECMWF's website, total precipitation is the sum of large-scale & convective precipitation. It seems that the total amount of precipitation has been split into two parts in the bar graph in Meteogram: the large-scale term and convective term. Furthermore, the sum of 'Rain' and 'Covective' is exact the value in basic list, which might indicates the total precipitation. As a result, the term 'Rain' might be interpreted as the large-scale precipitation part in Meteogram.

@greatkingnan Hello, the Rain, Thunder layers shows data for last 3 hours. The detailed forecast shows data calculated for 3hr or 1hr depending if you are Premium user or not. Therefore those values cannot be the same.
-
@korina Thanks for your help! Yes, I know exactly the data in Premium version and free version are different. But...Actually, I'm trying to figure out the differences between the rainfall values shown on the 'Rain & Thunder' layers and basic weather forecast on the same place. I just found they aren't exact the same value, especially for heavier rainfall cases, so I have no idea which one is correct. I guess it might be caused by the different definition of accumulated time period or the interpolation between each grid point.

@greatkingnan Hello, detailed forecast or Rain, Thunder layer shows different data based on different calculations. Detailed forecast is more precise if you want to check the predicted amount of precipitation.

Thanks, Korena for your very easy to understand description♪
Meteogram on Windy.com is my favourite weather forecast❤ -
What is the arrow on my location pointing towards? As I turn to face a different direction, the arrow swings to point toward something else. It's not making any sense to me; what is its purpose?
-
This arrow appears at your GPS position on the Radar layer and shows a fixed or inconsistent direction. It has no use.

Hi,
I wanted to know what criteria you use for the elaboration of the meteograms. this is the one from the ECMWF.https://confluence.ecmwf.int/display/FUG/Selection+of+grid+points+for+Meteograms

@fran_j Please have a look at https://community.windy.com/topic/10309/cloudbase-meteograms?_=1630065415375

Very good summary, very helpful to the net friend ~

On the Meteogram, what does the letter 'K: at the cloud base mean ? I have it set to show it on feet, but soem shows for example 17K
-
@mark-mansfield I think it means thousands (of feet) altitude.I think
-
@jp_windy65535 thank you, that does make sense, but then why does some heights show as feet , for example 6900, and others as 15K for example?

Hi, Precipitation is indicated in mm (millimeters) as I understand the intensity of precipitation? Or accumulation? if intensity, then probably the dimension is mm/minute? And if so, then it can be daily, semi-daily. can you clarify? Привет, осадки, указаны в мм ( миллиметры) это как понимаю интенсивность осадков? Или накопление? если интенсивность, то наверное размерность мм/минуту ? И если так, то она может быть суточная, полу суточная. можно уточнить?
-
@ilua1981
It is not the intensity of precipitation per minute. It is the rain forecast during 3 hours.

Hi! What does the number in the convective mean? Is it a probability of lightnings somehow? If there is 1.4 for example does it mean 1.4 mm of convective rain? Is there a way to predict the change of lightning somehow? Is 1.0 very little or a lot? Many thanks already! Windy is the best weather app :)
-
@timoti Hello, the number indicates what amount of rain is from convective origin.

Hi @Korina is it possible to display the "rain" and "convective rain" as a daily sum? For example, in the Figure shown below, the accumulated rain for martes 14 (tuesday) would be 15,4 mm of rain and convective rain. In case your answer is no, do you have a Python library which could advice me by solving my rerquirement.
Thanks!

@sochagota Hello, there is no way to display those values as daily sum. The alternative is to use Rain accumulation layer.
