Trewartha allows for the addition of precipitation pattern and hottest month (and coldest month) letters.
There are problems with the normal Köppen classification, especially in C-type climates. It's a very common source of complaints on this forum. But people hate just as much on Trewartha because both Mouteka and Tampa are Cf climates according to Trewartha. But are people forgetting that you can actually add letters for the hottest month temp (and coldest month temp) and precipitation pattern for pretty much all the different climate classes? Precipitation letters don't tend to be included for E and D climates, but there is no reason they can't be added since there's no mixing of letters and everyone understands what s, f and w means.
Honestly, when you include the temp/precipitation letters in the Trewartha system, it's pretty much perfection. I honestly don't see any problems whatsoever. The only problem I see personally is that oceanic subpolar climates apparently start at winter means of -10'C instead of -3'C or 0'C, but this can be mitigated by using the optional winter-temp letter. Feel free to point out some issues if you want though.
Here's a list of some cities when adding precipitation and hottest month letters.
Nikkaluokta: Ecfl
Reykjavik: Eofl (Eoflk with the winter temp letter included)
Umeå: Eofl/Dcfl
Stockholm, Oslo, Helsinki: Dcfb
London, Copenhagen: Dofb
Portland, Seattle: Dosb
Toronto, Buffalo: Dcfb/Dcfa
NYC: Dofa
Raleigh: Cfa (Cfak if you include the winter letter)
Tampa: Cfh (Cfhl if you include the winter letter)
Mouteka: Cfl/Cfb
La Rochelle: Cfb
Eureka: Csl
San Francisco: Csl/Csb
LA: Csb/Csa
Nice: Csa
Beijing: Dcwa
Can we just make Köppen-Trewartha (K-T) the norm on this forum instead of Köppen-Geiger?
