<![CDATA[How to read thunderstorm intensity numbers ?]]>Hello guys..
When I touch the screen in thunderstorm option I see number I don't know how to read them, like 2.55|/km2 ? What does this mean 2.5 lighting strikes every somewhat in every km2? Or how
Thanks

Are you saying light/moderate/heavy is something you can display instead of I/km2?

It's very obvious now ..
Thank you and you're right it's better to see them as light / m / h better than specific numbers, I asked just to know how to read them because I'm trying learn more about weather models and maps etc.

Numbers after . are decimals.
(some countries use the comma symbol (,) as a decimal separator)
https://en.wikipedia.org/wiki/Decimal_separator

1 lightning/1km2 = 1x100 lightnings/1x100 km2 = 100 lightnings/100 km2
(multiply numerator and denominator x100).

My opinion: I suggest you to use this parameter as an light/moderate/heavy thunderstorm indication
instead of the precise arithmetic value.

So this is in one day? Because I see it change every 3 hours, also that means 1.00l/km2= is 100 lightning in 10x10 area 100km2 ?
Numbers before . Is hundreds
And numbers after . Is from 0-99 ?

Also keep in mind that:
0.16 l/km2 = 16 l/ 100km2 = 16 lightnings in an area of 10x10 km (in one day).
