📖 How Köppen Classification Works

First Letter: Main Group

A = Tropical (Tcoldest >18°C)
B = Dry (Evaporation > Precipitation)
C = Temperate (Tcoldest 0-18°C)
D = Continental (Tcoldest <0°C)
E = Polar (Twarmest <10°C)

Second Letter: Precipitation

W = Desert (very low precip)
S = Steppe/Semi-arid
f = No dry season
s = Dry summer
w = Dry winter
m = Monsoon
T = Tundra | F = Ice cap

Third Letter: Temperature

h = Hot (mean >18°C)
k = Cold (mean <18°C)
a = Hot summer (>22°C)
b = Warm summer (10-22°C)
c = Cool summer (1-3 mo >10°C)
d = Very cold winter (<-38°C)

??? Avg Temp ~0% Earth Coverage <-38°C Would Need 📚 Theoretical 📚 Theoretical Climate Type This climate classification exists in the Köppen system but has no verified locations on Earth. It would require an extremely unusual combination of factors that don't naturally occur together on our planet. 🔬 Required Conditions ❄️ Coldest month avg below -38°C ☀️ Dry summer (Mediterranean pattern) 🌡️ Only 1-3 months above 10°C 🏔️ Would need extreme elevation + latitude 📍 No known location meets all criteria 🤔 Why It Doesn't Exist 🌍 Dry summer = subtropical high influence ❄️ Extreme cold = far from subtropical 🔄 These patterns are geographically opposed 🏔️ No terrain creates these conditions 📊 Mathematical possibility, physical impossibility
