I can’t reply. I’m not in the Windy organisation.
You should read this thread

@bmmaxwell
Windy visualizes weather models, while these Surface Analysis maps are drawn by meteorologists, forecasters. But Windy doesn't employ any of them. Perhaps one day AI will be able to plot them?

@chis
I do not agree with you.
You are proposing to add wrong values just to show an infinitesimal amount of rain spread over one hour !
If you get 0.2mm for 3h it is because for 1h you have something like 0.05 + 0.04 + 0.07 = 0.16 rounded to 0.2.
If Windy introduce wrong values like in your proposal, many users would claim that the total of the 1h-values is not equal to the 3h-value.

In addition when a rain amount is displayed in the 3h-table, there is a “rain” pictogram and this pictogram is kept in the 1h-table even without rain amount.

I don't think the weather radar ever covered the entirety of Brazil in Windy. You are probably confusing it with other apps that show so-called radar coverage across the globe but are just satellite images that look like radar images but are not real radar data.

@chis said in Rainfall figures are very different between 3 hourly and hourly displays:

@idefix37 0.1mm seems worth including, then I wonder whether you could have a smoothing algorithm that spreads the rain across the same duration and achieving the same total, just that some periods with less than 0.1mm wouldn't get a value and others would, which would appear as sporadic rain which is really what it's like in these situations anyway.

I don’t understand. You were complaining about not seeing values ​​below 0.1 mm of rain for one hour, while you see more than 0.1 mm for three hours. Am I right ?

Having 1.5mm and 0.7mm makes a bit of a difference if you're in the outdoors. I'd always rather know the total expected and over what duration.

Yes but here we are talking about less than 0.1mm over 1 hour.

@Airton-de-Oliveira-Junior

In which area did weather radar exist 2 years ago?

@Lucas-Monteiro-Lucas
Do you mean that these radar installations are out of service?
Which ones ?

@coastal-tune
Hello,
Please could you tell us where exactly to see these temperature differences ?

@chis
These differences are only due to the fact that Windy does not display values below below 0.1mm.
Note that 0.1 mm resolution is a WMO standard for rain gauges. Rainfall traces of 0.1mm are almost nothing, so in a forecast what does it matter?
May be values ​​below 0.1 mm should not be considered in the 3-hour cumulative to show both panels consistent.

You can provide some details about your problem, if you have one.
And first, are you using the mobile app or the browser version?
