Temperate and Polar Climate Zones

A condensed, point-by-point summary of the module, for reviewing right before a test or exam.

1. Humid Continental and Humid Subtropical Climates. Köppen's C and D climates define the four-season continental interiors and humid subtropical coasts.
2. Mediterranean Climate Regions. Five widely separated coasts share a rare summer-dry, winter-wet climate driven by shifting subtropical highs.
3. Oceanic and Marine West Coast Climates. Warm currents and steady westerlies give west-coast mid-latitudes mild, wet, low-variance climates year-round.
4. Temperate Deciduous and Mixed Forests. Broadleaf trees that shed leaves each autumn dominate three disjunct mid-latitude belts across the hemisphere.
5. Steppe and Continental Grassland Climates. Semi-arid mid-latitude grasslands span the Eurasian steppe, the Great Plains, and the Pampas.
6. Subarctic and Taiga Climate Zones. Subarctic climates hold Earth's most extreme temperature swings and sustain the vast coniferous taiga.
7. Tundra Climate and Polar Desert. Tundra and polar desert climates sustain permafrost, low vegetation, and Earth's driest, coldest landscapes.
8. Seasonal Change and Phenology in Temperate Ecosystems. Phenology tracks the seasonal timing of life cycles, a record now shifting measurably with climate change.
