It's also affected by the spin of the Earth. This pattern, called atmospheric circulation, is caused because the Sun heats the Earth more at the equator than at the poles. In comparison to the global average, the climate in the Baltic Sea region, including in Estonia, has warmed particularly fast. the local movement if air measured relative to Earth's surface. Global Atmospheric Circulation describes how air moves across the planet in a specific pattern. The global circulation would be simple (and the weather boring) if the Earth did not rotate, the rotation was not tilted relative to the sun, and had no water. GCSE geography students often get confused. stonethecrows555. Flashcards. Getting across the mechanisms involved in global atmospheric circulation, the heating effect of the equator plus the spinning effect, can be a tricky ! Introduction (5 mins) Set the context of the unit of work and what students will be covering over the eight lessons. Atmospheric circulation is the large-scale movement of air by which heat is distributed on the surface of the Earth. Match. This is because the UK is located close to the boundary of cold polar air moving for from the north and warm sub-tropical air moving up from the south. Explain how the global atmospheric system affects the weather and climate of the UK using key terminology. In the tropics, near the equator, warm air rises. It is the way in which heat is redistributed around the globe. anticyclone. Different weather systems (15 mins) In 1686 Halley associated the easterly trade winds with low-level convergence on the equatorial belt of greatest heating (i.e. Write. PLAY. Created by. Then, share the learning outcomes for the lesson. From synoptic climatology’s point of view, a question can be posed: is this warming caused by changes in the frequency of particular circulation types or has warmer weather started accompanying these types? Gravity. Even with disruptions like weather fronts and storms, there is a consistent pattern to how air moves around our planet’s atmosphere. Spell. The first attempt to explain the global atmospheric circulation was based on a simple convectional concept. Global Atmospheric Circulation. Global Circulations explain how air and storm systems travel over the Earth's surface. the thermal equator).These flows are compensated at high levels by return flows aloft. (6 marks) It is often cloudy and wet in the UK. It is essential that first an explanation or description of what global patterns of atmospheric heating and circulation is provided. Terms in this set (49) wind. STUDY. Explain how global atmospheric circulation affects weather; Lesson steps. This movement of air is caused by heat differentiation, meaning that the sun heats the earth unevenly, with the Equator receiving the most concentrated dose of heat. change in air pressure with distance. Atmospheric circulation, any atmospheric flow used to refer to the general circulation of the Earth and regional movements of air around areas of high and low pressure.On average, this circulation corresponds to large-scale wind systems arranged in several east–west belts that encircle the Earth. air pressure gradient. This difference in solar input generates major global patterns of atmospheric circulation: air that is strongly heated at the equator has the greatest tendency to rise. Learn. Air flow for no rotation and no water on a planet. Test. I have provided this lesson plus worksheet to help simply the physical processes involved for the middle ability and lower ability pupils.
