Cevven this map is a good example of why the Trewartha system is flawed. Southern Kansas/northern Oklahoma has an oceanic climate? Give me a break!

My suggestion would be to subcategorize Group D by adding a third letter to distinguish between the PNW and Upper South climates. Doa: Humid Temperate Dob: Temperate Oceanic Dca: Hot-Summer Continental Dcb: Warm-Summer Continental (Hemiboreal) |

Doa: Humid Temperate Dob: Temperate Oceanic Dca: Hot-Summer Continental Dcb: Warm-Summer Continental (Hemiboreal) Good breakdown! The only correction I would make is keep Temperate Oceanic simply as "Do" - and change Humid Temperate to "Dt" Difference between Do and Dt is Dt has a hot summer (72F and above mean temp). As for the subtropical (C) climates - I would split the Cf climates: q = mild winter; p = cool winter Cfq = mild winter (mean temp of coldest month at least 48F/8.9C) - transition to tropical Cfp = cool winter (mean temp of coldest month at least 32F/0C) - transition to temperate Cfp climates in the SE US: Raleigh, Birmingham, Atlanta, Columbia, Little Rock, Jackson, Jacksonville (NC) Cfq climates in the SE US: Orlando, New Orleans, Houston, Savannah, Jacksonville (FL), Tampa that's the way to separate cities with significantly warmer winters like Orlando (low 70s for highs and 50s for lows on average in Jan) from colder winter cities like Raleigh, Atlanta, or Charlotte (low-mid 50's for highs and 30s for lows on average in Jan). Mediterranean Climates (Cs) has of course, like Koppen, be separated into as well: Csa = hot summer Csb = warm summer |

Yeah I totally get it but someone in the City Data Weather forum said to understand this system, you have to change the way you view "oceanic". True oceanic climates tend to have warm summers where the average high temps don't reach above the low 80's. That's not the case with the inland south climates labeled as "Do" on this map, which all have HOT summers (outside of the highland areas in the South) |
