Document Summary
* avg t of coldest month is <= -3 c (26 f) & avg t of warmest month is > 10 c (50 f) * no "d" climates in the southern hemispheres; no large land masses in the correct latitudinal zone. Location: ~ 40 to 55 n; midwest u. s. to east coast, s canada; e. * large annual t variations; cp air dominates. Mechanisms: far northern latitudes = relatively low amounts of solar radiation & thus little energy (heat) Location: poleward of dfa, dfb, dwa, dwb climates, south of tundra, western alaska across canada to newfoundland; norway across russia to the pacific ocean. * exhibit the greatest annual t ranges (siberia up to 145 f) * precipitation < 50cm (20 in) per year. Mechanisms: high latitudes = little solar radiation = low t s. ** polar climates: locations with an avg t of the warmest month < 10 c (50 f).
