🏔️ Katabatic Wind – Cold Wind Coming Down.
🔽 What is it?
A katabatic wind is a cold, heavy wind that flows downhill from high mountains or plateaus.
❄️ How is it formed?
-
At night, mountain tops lose heat quickly (radiation cooling).
-
The air becomes cold and dense.
-
This cold, heavy air slides down the slopes into valleys due to gravity.
🧊 Features:
-
Happens mostly at night.
-
Cold and dry wind.
-
Can be very strong (like in Antarctica or Greenland).
🌍 Examples:
-
Mistral Wind in France
-
Bora Wind in Europe
-
Chinook (partially katabatic) in North America
🏞️ Anabatic Wind – Warm Wind Going Up
🔼 What is it?
An anabatic wind is a warm wind that moves uphill during the daytime.
🌞 How is it formed?
-
During the day, sun heats the mountain slopes.
-
Air near the slopes becomes warmer and lighter.
-
This warm air rises up the slope.
🔥 Features:
-
Happens mostly in daytime.
-
Warm and moist wind.
-
Helps in forming clouds and rainfall on mountain tops.
🌍 Examples:
-
Common in Himalayas, Alps, and Rockies during summer days.
🧠 Easy Way to Remember:
Wind Type | Direction | Time | Temperature | Cause |
---|---|---|---|---|
Katabatic | Down the slope | Night | Cold | Cold air sinks |
Anabatic | Up the slope | Daytime | Warm | Warm air rises due to sunlight |
