Yup. 
Hmm, there is a slight chance I've asked you this before, but have you mapped out the climates of your world? You probably know I have... and to a greater extent than the actual topography of the worlds themselves. 

(I also just realized that a minor problem with extending the Köppen [or Trewartha, Rivas-Martinez, etc.] system is that the colors used would have to be different from those here and less distinct, due to it having more categories. That may be ameliorated somewhat, though, by the limits of climatic diversity—for instance, the extremely continental [D{x}d] climates aren't forecasted to be present on either 22nd century Earth according to the RCP-8.5 scenario or on Yān, and I don't think Yān would have any subpolar/subalpine oceanic/highland [C{x}c] climates.  )

Y'know,  I've actually never gotten around to a climate map.
Ive made several drafts of land maps but I find things often shift around on me for one reason or another, I suppose because I keep learning new bits of geography or the nitty-gritty of plate tectonics that can make my old maps defuct, usually having to go back and try to balance out the science with the art. Compared to normal cartography climate mapping has always seemed a tad daunting, especially given the my tendency to move shit around, but if I had to say one thing it's that my world is likely rather cold compared to most earth-like planets, with a larger diversity of climates and peoples closer to the equatorial line, in fact I suppose I could say that tropics just aren't a thing, there'd still be deserts of course but likely more akin to those of Mongolia than northern/central Africa.
Right'o, I'll cease my rambling for now, but thanks for asking! Really got me thinking about things.

Ah, OK.  BTW, you're very welcome for the food-for-thought (there'll be some more later in this comment). 

 Hmm, what do you mean by "the tropics just aren't a thing"? Because the equatorial areas of any planet with a relatively low axial tilt and a low eccentricity will have temperatures that are nearly constant throughout the year. This would mean that in all but the coldest of habitable planets they would be frost-free year-round, as frost at one time of the year would mean frost at all times and for the vast majority of the planet's surface, as equatorial regions (surprise!) tend to be among the warmest areas of the planet*. In my cooler habitable planets Merém and Maryias, the lowland tropics would be very similar to that of the Tierra templada and Tierra fría in the corresponding latitudes in Latin America, the New Guinea Highlands, etc. While too cool to grow many tropical crops, these areas are notably ecologically and agriculturally distinct from actual temperate areas due chiefly to their very subdued seasonal pattern**.

*Though counting the highest monthly temperatures, the outer- and subtropics tend to be marginally hotter than the equator even in areas and times with similar rainfall—there are no equatorial areas with the unremitting brutality of Green Canyon  in July and August, for example.
**The Ecuadorian, Columbian, and North Peruvian sections of those, being located in the equatorial tropics have no seasonal temperature variation whatsoever, while the South Peruvian, Bolivian, and Mexican/Guatemalan sections (in the outer tropics) show some variation. This is why frost can occur in winter in Mexico City but not in Quito, and why the higher Tierra helada is pretty much completely inhospitable in the equatorial regions but supports a decent human population in the outer-tropical Altiplano (due to lack of summer frost).
