Classify Climate Pattern before Naming Biome

HL only

First identify heat level, seasonal range and rainfall timing; only then infer the likely biome.

Equatorial climates stay hot and wet; seasonal tropical climates alternate wet and dry; maritime temperate climates have smaller temperature ranges; continental climates have stronger seasons; polar climates are cold with short growing seasons.

Two temperate sites may differ: the maritime site has mild winters, while the continental site has hotter summers and colder winters.

A smaller annual temperature range because nearby ocean stores heat.

‘Temperate’ is not one climate pattern; seasonality and maritime/continental position refine the prediction.
