In the UK the most common winds (known as the prevailing winds) are from the west or south-west. These winds arrive in Britain after crossing the Atlantic Ocean, from which they pick up moisture. The air rises as it reaches higher ground, cools and falls as rain. The map below shows the location of hills and mountains.
What direction is the prevailing wind?
Generally, prevailing winds blow east-west rather than north-south. This happens because Earth’s rotation generates what is known as the Coriolis effect. The Coriolis effect makes wind systems twist counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
What is the prevailing wind in London?
The prevailing wind is west-southwest. Because of the sheltering effect of the Chiltern Hills and North Downs, the city has slightly less rainfall than the Home Counties.
What are the prevailing winds in Europe?
The westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude.
What is prevailing wind direction in east Anglia?
The prevailing wind direction is from the west, although during spring there are often winds coming from the north east, caused by high pressure building up over Scandinavia. Average monthly wind speeds vary typically from 12 knots in the summer months to 21 knots in the winter months.
What do we mean by prevailing wind?

What is the prevailing wind in Scotland?
WEATHER AND CLIMATIC CONDITIONS. Scotland has a maritime climate that is strongly influenced by the oceanic waters of the North Atlantic and prevailing south-westerly winds.
Which wind direction is the strongest?
Winds in the upper levels will blow clockwise around areas of high pressure and counterclockwise around areas of low pressure. The speed of the wind is determined by the pressure gradient. The winds are strongest in regions where the isobars are close together.
