# Intuitive explanation of precipitation amount

I'm trying to learn how to make sense of numbers in a forecast. I can interpret temperature and wind speed, but I don't know what to make of rainfall. What does it mean, for a human, that there will be (for example) 0.5mm precipitation? Is it a lot or not? Is there a reference online describing precipitation amounts in everyday terms? I've been looking for something like that, but found nothing, only formal definitions of measurement.

• You have to specify why the Wikipedia explanation doesn't work for you. – Deer Hunter Dec 24 '14 at 23:11
• @DeerHunter It's okay, just not specific enough. In my experience, there's a difference between 0.5mm and 1.5mm, both of which fall in the light rain'' bracket. – Jan van Bloem Dec 25 '14 at 9:45
• @DeerHunter to be fair, I do not see an explanation on that particular link? – Isopycnal Oscillation Jan 1 '15 at 7:43
• You won't distinguish precip intensity from storm total precip amounts. You need the precip rate for that. – casey Jan 1 '15 at 13:15
