The distribution of large-scale ecosystems (biomes) is determined by climate. The page references refer to the Oxford textbook. This animation shows the global atmospheric circulation in a cross section introducing the Hadley cell, the Ferell cell and the Polar Cell. There is more energy at the tropics than at the poles, creating an imbalance. The general atmospheric circulation model works by: - Pressure belts • Air at the equator is heated so it rises in LOW PRESSURE conditions and flows towards the poles. Atmosphere and climate Heat from the equator is transferred around the globe in three cells that connect with each other, known as the tri-circular model. As it rises it cools and condenses.

A tropical storm is a very powerful low-pressure weather system which results in strong winds (over 120 km/h) and heavy rainfall (up to 250 mm in one day). See more ideas about Atmospheric circulation, Meteorology, Earth science. Global atmospheric circulation The movement of air across the planet occurs in a specific pattern. The air rises and expands creating low pressure. These circulation cells move over land and sea to redistribute the energy, from the equator to the poles in both hemispheres, trying to even out the energy imbalance. Global Atmospheric Circulation - GCSE AQA 9-1. A simple sheet that uses a cross section diagram, rather than the more complicated global one used in the textbook. See more ideas about Geography revision, Gcse geography revision, Gcse geography. - AQA, Home Economics: Food and Nutrition (CCEA). The cause of these atmospheric movements is the difference in temperature between equatorial regions and polar regions, this is caused by distance from the sun and the amount of atmosphere to travel through.
