Katabatic wind is generated by gravity and blows down to the sea-level coast from the polar plateau, and is constant. The plateau sits on an ice sheet that is nearly two miles thick.
Valley breeze is a type of wind in the mountains. Katabatic wind is down hill wind.
Katabatic winds blow down from high mountains, plateaus and hills to valleys and plains below, whereas Anabatic winds are totally opposite of it. (Vice Versa)(also they can shit)

From Wikipedia:"A katabatic wind, from the Greek word katabatikosmeaning "going downhill", is the technical name for a drainage wind, a wind that carries high density air from a higher elevation down a slope under the force of gravity."In Antarctica, katabatic winds swirl down to the beach -- about 750 miles -- from the elevated South Pole, which sits at an elevation of 9,300' (2900m), however the equivalent pressure elevation, based on polar atmospheric conditions, will vary from 10,800 (3300m) to 13,120 (4,000m).
Katabatic winds, this is word for word whats written on my physcial geo homework haha
You may be thinking of Katabatic wind, winds that flow downhill based on the force of gravity.The flow begins at the South Pole, which sits on nearly two-miles thick of ice, and flow downhill to sea level.
Antarctica is the windiest place on earth. The average windspeed is 67km/h (44mph) and the highest windspeed recorded is 320kmh( 198.8 mph). Violent katabatic winds are common. These are caused by heavy cold air falling towards the ocean and gathering speed. Air at Pole is slower, but with a severe wind chill factor.The wind blows in Antarctica all of the time, based on the nature of katabatic winds that flow downhill from the height of the polar plateau, coupled with the spin of the Earth, which is notable in polar regions.
Wind on the Antarctic continent is fed by the rotation of the earth. These Katabatic winds roar down the polar plateau -- two miles thick of ice at the South Pole -- and blow constantly. Blizzards are common in Antarctica.
The wind speed you quote is an exaggeration.The top wind speed measured on the continent is just under 200Km per hour. It is caused by the Katabatic winds that fall downhill from the polar plateau, which is about 2,835m above sea level. These winds are caused by gravity and the rotation of the earth.
At least two factors propel the wind in Antarctica.First, gravity pulls the cold polar wind off the polar plateau -- katabatic wind.Second, the earth spins on its axis which is at the South Pole, which also causes wind.The wind blows, generally, all the time in most locations on Antarctica.
There may be a typo in your question. Antarctica is often called home of the wind, because of the strong, constant Katabatic winds that blow to the coasts from high on the polar plateau.
The wind blows constantly on the Antarctic continent, principally because the earth pivots on its polar axis and the Katabatic winds created thereby seek lower levels from the nearly two-mile high thickness of ice at the South Pole.
