气候带塑造生命：温度与降水如何定义地域

Earth’s climate zones form mainly because of uneven solar heating and atmospheric circulation.
Tropical zones near the equator stay warm year-round and receive heavy rainfall almost daily.
In contrast, deserts lie around 30° north and south where dry air sinks and blocks clouds.
Temperate zones experience four distinct seasons due to shifting jet streams and frontal systems.
Polar regions remain frozen most of the year because sunlight strikes at a very low angle.
Each zone supports unique ecosystems—from rainforest canopies to tundra mosses and lichens.
Climate also influences architecture, clothing, agriculture, and even cultural festivals around the world.
Farmers in Mediterranean climates grow olives and grapes during dry summers and mild winters.
Modern climate change is shifting these zones, pushing forests, insects, and diseases into new areas.
Mapping climate zones helps scientists predict how ecosystems and societies may adapt over time.
