Which ocean current warms the climate of North Western Europe?
The Atlantic overturning is one of Earth's most important heat transport systems, pumping warm water northwards and cold water southwards. Also known as the Gulf Stream system, it is responsible for the mild climate in northwestern Europe.
What is the usual wind pattern within a northern hemisphere low pressure system?
In summary, for the Northern Hemisphere: Low pressure is called a cyclone and has anticlockwise winds blowing around it. High pressure is called an anticyclone and has clockwise winds blowing around it. The wind tends to blow along the pressure contours.
At what approximate altitude can stratospheric ozone be found?
Most ozone (about 90%) is found in the stratosphere, which begins about 10–16 kilometers (6–10 miles) above Earth's surface and extends up to about 50 kilo- meters (31 miles) altitude.
Where do most of Earth's weather events take place?
Troposphere. Known as the lower atmosphere almost all weather occurs in this region. The troposphere begins at the Earth's surface and extends from 4 to 12 miles (6 to 20 km) high. The height of the troposphere varies from the equator to the poles.
Why is there no Coriolis force at the equator?
Because there is no turning of the surface of the Earth (sense of rotation) underneath a horizontally and freely moving object at the equator, there is no curving of the object's path as measured relative to Earth's surface. The object's path is straight, that is, there is no Coriolis effect.
What would happen if the Coriolis effect didn't exist?
Without the Coriolis effect air would simply flow directly from areas of high pressure to areas of low pressure. The Coriolis effect influences the global wind patterns and gives the UK is prevailing south-westerlies.
How many layers does the atmosphere have?
Earth's atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere.
What is the ozone gas around the Earth called?
ozone layer, also called ozonosphere, region of the upper atmosphere, between roughly 15 and 35 km (9 and 22 miles) above Earth's surface, containing relatively high concentrations of ozone molecules (O3).
How many ozone layers are there?
two different layersOzone is found in two different layers in Earth's atmosphere.
Which two gases make up most of the atmosphere?
Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases.
Which layer of the atmosphere is known as the House of mankind?
Troposphere. The troposphere is the lowest layer of our atmosphere. Starting at ground level, it extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. We humans live in the troposphere, and nearly all weather occurs in this lowest layer.
Are all clouds in the troposphere?
Most types of clouds are found in the troposphere, and almost all weather occurs within this layer. The troposphere is by far the wettest layer of the atmosphere (all of the other layers contain very little moisture). This diagram shows some of the features of the troposphere.
What is the usual surface wind pattern around the eye of the Northern Hemisphere hurricanes?
In the lower troposphere (near the earth's surface), winds spiral towards the center of a hurricane in a counterclockwise direction in the Northern Hemisphere and in a clockwise direction in the Southern Hemisphere.
How do winds flow around a low pressure center in the Northern Hemisphere in relation to isobars drawn on a map?
The Coriolis force, however, deflects the direction of the flow of the air (to the right in the Northern Hemisphere) and causes the air to flow parallel to the isobars. Winds in the upper levels will blow clockwise around areas of high pressure and counterclockwise around areas of low pressure.
What direction do the winds of a high-pressure system move in the Northern Hemisphere?
In the northern hemisphere this wind spiral flows in an anticlockwise direction around areas of low pressure and in a clockwise direction around areas of high pressure - the opposite is the case in the southern hemisphere as the Coriolis force acts in the opposite direction.
How does wind move at a low pressure center?
A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation.
