🌍 DETAILED CLASSIFICATION OF WORLD CLIMATES

1. Tropical Climates (A)

• Main feature: Hot and humid all year.
• Temperature: Monthly average always above 18°C (64°F).
• Subtypes:
  • Af – Tropical Rainforest: Rain falls all year (e.g., Amazon, Malaysia, Indonesia).
  • Am – Tropical Monsoon: Short dry season (e.g., West coast of India, Sri Lanka).
  • Aw/As – Tropical Savanna: Distinct dry and wet seasons (e.g., East Africa, Thailand, Brazil).

---

2. Dry Climates (B)

• Main feature: Evaporation exceeds precipitation.
• Subtypes:
  • BWh – Hot Desert: Very hot and dry (e.g., Sahara, Arabian Desert).
  • BWk – Cold Desert: Cold winters (e.g., Gobi Desert, parts of Iran).
  • BSh – Hot Semi-Arid (Steppe): Slightly more rain than deserts (e.g., parts of northern Africa).
  • BSk – Cold Semi-Arid: Cooler steppe zones (e.g., Mongolia, Kazakhstan).

3. Temperate Climates (C)

• Main feature: Mild winters and distinct summers.
• Subtypes:
  • Cfa – Humid Subtropical: Hot, humid summers and mild winters (e.g., southern USA, southern Japan).
  • Cfb – Oceanic (Marine West Coast): Moderate temperatures year-round with steady rain (e.g., UK, New Zealand).
  • Cfc – Subpolar Oceanic: Cooler than Cfb (e.g., coastal Norway).
  • Csa – Hot-summer Mediterranean: Dry summers, rainy winters (e.g., Italy, Greece, California).
  • Csb – Warm-summer Mediterranean: Milder than Csa (e.g., parts of Portugal, central Chile).

4. Continental Climates (D)

• Main feature: Large temperature variations between seasons; cold winters.
• Subtypes:
  • Dfa/Dfb – Humid Continental: Hot summers, cold winters (e.g., central USA, eastern Europe).
  • Dfc – Subarctic: Short summer, long and harsh winter (e.g., Siberia, northern Canada).
  • Dfd – Extreme Subarctic: More severe cold (e.g., Yakutsk, Russia).

---

5. Polar Climates (E)

• Main feature: Always cold; no month averages above 10°C.
• Subtypes:
  • ET – Tundra: Some snow melts in summer; mosses and shrubs grow (e.g., coastal Greenland, Alaska).
  • EF – Ice Cap: Perpetual freezing temperatures (e.g., interior Antarctica, central Greenland).

---

6. Highland Climates (H)

• Main feature: Cooler temperatures due to high elevation.
• Occurs within any climate zone, depending on altitude.
• Examples: Himalayas, Andes, Alps.
