Air rising causes the formation of clouds, which brings rainfall. Depressions often move eastwards across the UK, bringing changeable weather as they travel. … The diagram below shows the changing weather that the warm and cold fronts bring as they move towards the east.
What affects weather in the UK?
The main influence on Britain’s climate which are important are latitude , altitude ,distance from the sea, ocean currents and the prevailing winds.
What are the causes of extreme weather in the UK?
Extreme weather in the UK
- Drought – caused by a lack of rain.
- Flash floods – caused by too much rain in a short period of time.
- Strong winds and storms.
- An extreme cold spell.
- An extreme heat wave.
What controls the weather in the UK?
The position of the jet stream over the UK determines the type of weather we experience. … The direction and angle of the jet stream arriving at the UK will determine what source of air (i.e. cold, dry, warm, wet, from maritime or continental sources) the UK experiences.
What causes wind?
Wind is the movement of air caused by the uneven heating of the Earth by the sun. … Warm equatorial air rises higher into the atmosphere and migrates toward the poles. This is a low-pressure system. At the same time, cooler, denser air moves over Earth’s surface toward the Equator to replace the heated air.
Why does the UK not get extreme weather?
The British Isles undergo very small temperature variations. This is due to its proximity to the Atlantic, which acts as a temperature buffer, warming the Isles in winter and cooling them in summer. Coastal areas tend to be more temperate than inland areas, as the influence of the ocean is less acute.
What conditions cause a storm?
There are three basic ingredients needed for thunderstorm development: moisture, an unstable atmosphere, and some way to start the atmosphere moving. Moisture is necessary to produce the thunderstorm clouds and precipitation.
How weather is formed?
Weather on Earth is caused by heat from the sun and movement of the air. … Moisture or water vapor (gas) in the air also affects the weather. The amount of moisture in the air affects how clouds form and whether the clouds produce fog, rain, or snow, as well as extreme weather, such as storms and blizzards.
What makes the weather hot?
During the summer, the sun’s rays hit the Earth at a steep angle. The light does not spread out as much, thus increasing the amount of energy hitting any given spot. Also, the long daylight hours allow the Earth plenty of time to reach warm temperatures.
What type of weather is brought by depressions?
An area of low pressure is called a depression . Air rises in a depression so clouds and rainfall are formed. Depressions therefore bring unsettled weather and rain. Winds are normally stronger.
What are the 2 causes of wind?
The two main causes of large-scale atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect).
What is the windiest place in the world?
Commonwealth Bay, Antartica
The Guinness Book of World Records and National Geographic Atlas have both listed this bay in Antarctica as the windiest place on the planet. Katabatic winds in Commonwealth Bay are recorded at over 150 mph on a regular basis, and the average annual wind speed is 50 mph.
Which is responsible for creating wind?
Wind is air in motion. It is produced by the uneven heating of the earth’s surface by the sun. Since the earth’s surface is made of various land and water formations, it absorbs the sun’s radiation unevenly. Two factors are necessary to specify wind: speed and direction.
