I do not know this unit "L/100km" and I use L/m²
I do prefer neither one nor the other, just need to understand the difference and the correspondence :)

Hi,

Alright, thank you for you explanation.

So, the 3hr rainfall forecast is not an intensity but a rain accumulation according to you in "mm" ?
Because the intensity are defined by Meteo France (in France) as:
1 > 3 mm /hr > light rain
4 > 7 mm /hr > moderate rain
8 and more mm /hr > strong rain

if it was an intensity on the rain forecast (Arome Model), we should have had at least 24 mm/3hrs even more than 30 mm/3hrs. As it fell in 1 hour around 12 mm.

And if I comme back to my example: the forecast was't 12 mm/ 3hr or 11 + 12 in 6 hours and in 6 hours it fell around 50 - 60 mm.

Nicolas

Hi All,

I do not understand the rain unit
Is it the intensity?
Because: Intensity= Height/Time
Usually it is mm/h
How can we translate the unit on Windy?
I already checked some others posts and you replied that it mm/3hrs what I saw.
The fact is Official Website are using the height of rain or the intensity with mm/hour

For example, today the 07.08.2019, on Windy the prediction was around 12mm/3hr on Saint Clair du rhone around 7 o'clock - France. But if we user mm/hr unit, it is 4mm/hr as intensity which is not the one we got on the city.

Have you an explanation? please

Thanks

Nicolas
