But why does the air get cooler and windier? It is windy high up in the atmosphere as the effect of gravity is reduced and cooler because air temperatures decrease as you get closer to the poles. Therefore gale force winds are stronger and more common at the top of mountains than at sea level.
Is it more windy on a mountain?
Ridge lines of mountains get even more wind, he said, with Mount Washington in New Hampshire holding the record for directly measured surface wind speeds, at 231 miles per hour. But such extremes are mostly found in the higher mountains, around 6,000 feet and above, closer to the jet stream.
Why are mountains always windy?
During the day, the sun heats up mountain air rapidly while the valley remains relatively cooler. Convection causes it to rise, causing a valley breeze. At night, the process is reversed. During the night the slopes get cooled and the dense air descends into the valley as the mountain wind.
Do mountains affect wind?
Mountains make a barrier for moving air. The wind pushes air, and clouds in the air, up the mountain slopes. The atmosphere is cooler at high elevations, and there is less of it: lower pressure makes it hard for lowland animals to get enough air to breathe.
Do mountains slow down wind?
Mountains may also restrict or slow down air flow. This restriction may also result in lifting air to high altitudes and creating clouds prior to the air reaching the slopes of the mountain.
Can you walk in 30 mph winds?
Walking in a 30 mph wind can be tricky, at 40 mph you could be blown off balance and at 60 mph it is almost impossible to walk. The wind speed given by the BBC or local radio station will be at sea level. … At 900m above sea level the wind could be blowing about three times stronger than at sea level.

What happen when the wind rise across the mountain?
When wind blows across a mountain range, air rises and cools and clouds can form. … When this happens, the air will rise and cool, and this cooler air is no longer able to hold all of the water vapor it was able to hold when it was warm.
Why does mountain weather change so quickly?
The main reason is that changes in altitude (= temperature) can be very rapid in the mountains, much morso than on the prairies. This is due to “Orographic Lift”, in which air is pushed aloft by elevation changes as it moves over rising terrain.
Which side of the mountain is more often cloudy and which side is more often clear?
The Windward side of the mountain is more often cloudy, while the leetward side is more often clear.
How does wind occur near mountains in the daytime?
During the day, sunlight warms the land and air in the Valley and along the slopes of the mountains. The warmer and less dense air near the ground rises during the day pulling more air through the valley floor. This gentle upslope wind known as a valley breeze. … This is called a mountain breeze.
Do valleys have a lot of wind?
But even on most slightly windy evenings, it’s likely that the winds in valleys are calmer than on the mountains (which tend to be much higher than other places on Earth), and also probably calmer than similar areas in the Plains.
