The Köppen-Geiger climate classification scheme divides climates into five main groups (A, B, C, D, E), each having several types and subtypes. Each particular climate type is represented by a two- to four-letter symbol.

Group A: Tropical/megathermal climates:
Tropical rainforest climate (Af)
Tropical monsoon climate (Am)
Tropical wet and dry or savanna climate (Aw)

Group B: Dry (arid and semiarid) climates:
Desert climate BW: Hot desert (BWh), Cold desert (BWk)
Steppe climate (Semi-arid) BS: Hot steppe (BSh), Cold steppe (BSk)

Group C: Temperate/mesothermal climates:
Dry-summer or Mediterranean climates (Csa,Csb)
Temperate or subtropical hot-summer climates (Cwa,Cfa)
Maritime temperate climates or Oceanic climates (Cwb, Cwc,Cfb, Cfc)
Maritime subarctic climates or subpolar oceanic climate (Cfc)
Temperate highland climates with dry winters (Cwb, Cwc)
Dry-summer maritime subalpine climate (Csc)

Group D: Continental/microthermal climates
Hot summer continental climates (Dsa, Dwa, Dfa)
Warm summer continental or hemiboreal climates (Dsb, Dwb, Dfb)
Continental subarctic or boreal (taiga) climates (Dsc, Dwc, Dfc)
Continental subarctic climates with extremely severe winters (Dsd, Dwd, Dfd)

Group E: Polar and alpine climates:
Tundra climate (ET)
Ice cap climate (EF)

Ecoclimax is defined by Odum (1969) as the culmination state after a succession in a stabilized ecosystem in which maximum biomass (or high information content) and symbiotic function among organisms is kept per unit of available energy flow.
