Climate Zones
Tropical, temperate and polar zones differ by temperature and rainfall.
About this topic
Climate zones are based on temperature and precipitation. Tropical zones (near the equator) are hot and wet; arid zones are dry; temperate zones have moderate temperatures with distinct seasons; continental zones have large temperature ranges; polar zones are cold. The Köppen system classifies climates by letters.
Latitude is the main factor, but altitude, distance from the sea, ocean currents and mountain ranges also matter. Climate zones influence ecosystems, farming and where people live.
Compare three cities: Singapore (near the equator) has about 27 degrees C every month and rain all year; Cairo has a hot desert climate with under 30 mm of rain annually; and Moscow has warm summers and freezing winters. Climograph charts show average monthly temperature as a line and rainfall as bars, giving a quick fingerprint of a place. Mediterranean climates have hot dry summers and mild wet winters, which is why they suit olives and grapes, and are found in California, Chile, South Africa and southern Australia as well.
Vegetation, called biomes, follows climate: rainforest, savanna, desert, grassland, temperate forest, taiga and tundra. The Koppen system uses letters such as A for tropical, B for dry, C for temperate, D for continental and E for polar. Knowing a climate helps design buildings, crops and clothing, and predict where zones may shift as the world warms. A common misconception is that the equator is the hottest everywhere; deserts at 20 to 30 degrees often reach higher temperatures because there are no clouds. Another is that altitude does not matter; temperatures fall about 6.5 degrees per km, so tropical mountains can have snow.
