Albedo is the rate at which things are radiated back. 1 of 17 What is the role of the Ferrel Cell? Circulation that brings warm air north. 2 of 17 What is the role of the Hadley Cell? A circulation cell near the equator responsible for storms at the equator and desert belts north and south of the equator. 3 of 17 What is the role of the Polar Cell? A circulation furthest from the equator that brings cold air south. 4 of 17 What is the Coriolis effect? The deflection of air movement by the Earth's rotation. This causes anti-clockwise winds around low pressure and clockwise winds around high pressure. 5 of 17 What do areas of low pressure bring? Warm air rises causing wet, windy and stormy conditions. 6 of 17 What do areas of high pressure bring? Cold air sinks causing calm, clear and dry conditions. 7 of 17 What affects the location of deserts? Global circulation affects the location of deserts. Usually they are formed around the equator and therefore receive the most intense radiation. 8 of 17 What affects the location of rainforests? Warm conditions near the equator creates wet climates as water is evaporated. Low pressure also causes stormy conditions. 9 of 17 What is insolation? Short wave solar radiation received in the Earth's atmosphere or at it's surface. 10 of 17 What causes an energy surplus? If the incoming insolation exceeds outgoing radiation. 11 of 17 What causes an energy deficit? If outgoing radiation exceeds the incoming insolation. 12 of 17 What evidence shows proof of climate change? • Photographic Evidence • Distribution of animals • Layers of ice • Sea levels rise • Tree Rings 13 of 17 Who are the intergovernmental panel on climate change (IPCC)? An organisation that collect evidence to prove the existence of climate change. 14 of 17 What is a tropical storm? A deep area of low pressure formed in the tropics that are capable of devastating large areas. 15 of 17 What conditions are needed for a tropical storm? • Deep Water • 5 - 30 Latitude • Water of temperatures 26c • Strong Winds 16 of 17 What is a tsunami? A giant sea wave travelling at high speeds. They are a secondary impact usually caused by an earthquake. 17 of 17
