The Köppen–Geiger climate classification made simpler (I hope so)

[Charerg]

Ok now I understand we you said the letters could be confusing. Indeed using the same letters for

• At least 2/3 (or ~67%) of rain occurs in summer (W aridity group, use threshold T_ann*20+280)
• Between 1/3 to 2/3 (34-66%) of rain in summer (F aridity group, use threshold T_ann*20+140)
• Less than 1/3 (~33%) of rain falls in summer (S aridity group, use threshold T_ann*20)

as s,f,and w climates, doesn't make much sense since they are 2 different things.
I guess I'm just repeating you.

I personally don't really care how Koppen name them, if it's too confusing we should change the naming, assuming we keep them.

Arid
Average
Wet

West coast
Something (Faoofa?)
East coast (the dry summer is more prominent on east coasts, or the eastern sides of mountains in the case of Central Asia). it is the opposite for w pattern.
Now I remember I used to say precipitation pattern. For example, Brest in Brittany has a Cfb climate with a s pattern because the summer is drier than winter but not dry enough to qualify as a s climate.

I don't think they have been named as such, I just adopted the W/F/S terminology since it works for me (and kind of assumed everyone was "on the same page" as myself, I guess).

But essentially it's the percentage of total rainfall that falls in summer from 0-100% divided into even thirds. I guess you could call them the "winterwet third", "middle third" and "summerwet third", though tbh that could be even more confusing since "winterwet" is more or less the same same as "summer dry". But precipitation pattern sounds good, as long as you use capital letters when talking about the pattern, and lowercase when referring to the climate class, then at least I'll understand (not sure about anyone else though ).
