UPSC IAS 2020 Exam: Click here to get the Complete 30 Days Study Plan to score high in Prelims. They are of short duration, occurring over a small area but are violent. The geography is scientific in its orientation and hence the IAS Aspirants having Arts background find it very difficult to prepare the geography for the IAS Prelims Exam.Q1. Subsidence also evaporates most of the atmosphere's water vapor, so high-pressure systems are usually associated with clear skies and calm weather. General Circulation of the atmosphere is one of many concepts for UPSC Geography that candidates must familiarize themselves with. Over high pressure area the air will subside from above and diverge at the surface.Select the correct answer from the following codesa. They also require the optimum temperature to keep themselves warm and grow. Both 1 and 2d. Clear frontal system is visible in tropical cyclones.2. Dry air on the leeward side of sloped. After completing the Atmospheric Circulation and Weather Systems it becomes important for students to evaluate themselves how much they have learned from the chapter. Consider the following statements regarding frictional force acting on wind1. Extra tropical cyclones originate over land only.Select the correct answer from the following codesa. The pressure gradient is strong where the isobars are close to each other and is weak where the isobars are apart.Q3. Ans. Only 1 and 2c. These notes will also be useful for other competitive exams like banking PO, SSC, state civil services exams, and so on. (a) the Equatorial forest (b) the Himalayas  (c) the Siberian Plain  (d) the Deccan Plateau, Related: Subtropical High, Subpolar Low, Easterlies, Westerlies | Pressure Belts of World. Wind movement in the atmosphere may be classified into 3 broad categories: Primary, secondary and tertiary circulation. With reference to Inter Tropical Convergence Zone (ITCZ), which of the following is/are true?1. The Coriolis force acts perpendicular to the pressure gradient forceSelect the correct answer from the following codesa. Only 2c. 1,2 and 3Answer: dExplanation: The pattern of planetary winds largely depends on (i) latitudinal variation of atmospheric heating(ii) emergence of pressure belts (iii) the migration of belts following apparent path of the sun(iv) the distribution of continents and oceans (v) the rotation of earth.Q7.

Geography section provides you all type of mcq questions on Atmosphere with explanations. Only 2 and 3d. It is greatest in high altitudes.2. Both 1 and 2d. If you were the weather forecaster, what would you tell her? Various studies (Jaagus, 2006; Hoy et al., 2013; Cahynová and Huth, 2016) suggest that the changes in air temperature over the last decades have been due to the changes in atmospheric circulation.From synoptic climatology’s point of view, air temperature rise may either be caused by increased frequency of particular “warm” circulation patterns or they started to bring warmer air masses. The easterlies from either side of the equator converge in the Inter Tropical Convergence Zone (ITCZ).Q9. In the subtropical high-pressure belts near latitudes 30° N and 30° S (the horse latitudes), air descends … Tropical cyclones originate over land and sea.3. ATMOSPHERIC PRESSURE Do you realise that our body is subjected to a lot of air pressure. In the night the reverse happens. Atmospheric Circulation and Weather System Atmospheric Pressure is the weight of a column of air contained in a unit area from the mean sea level to the top of the atmosphere. Figure C. Walker Circulation. The rate of change of pressure with respect to distance is the pressure gradient. 2. It is zone of convergence of easterlies from either side of the equator.Select the correct answer from the following codesa. The rate of change of pressure with respect to distance is the pressure gradient. Around a high it is called anti cyclonic circulation. As a result, equator is a low pressure zone. Only 2 and 3d. It is greatest at the surface and its influence generally extends up to an elevation of 1 – 3 km. Only 2c. Consider the following statements 1. The pressure decreases with height. Only 1 and 2c. The land loses heat faster and is cooler than the sea. Only 2c. The cool air, of the high plateaus and ice fields draining into the valley is called katabatic wind.Q10. Oceanic water circulation is set in motion by general circulation of atmosphere.2. Top Ranking CBSE Sample Paper Books for 2021 Boards. The cyclone creates storm surges and they inundate the coastal lowlands. Coriolis forces is maximum at the poles and is zero or absent at the equator. Only 1b. The Earth's atmospheric circulation varies from year to year, but the large-scale structure of its circulation remains fairly constant. The extra tropical cyclone affects a much larger area as compared to the tropical cyclone. The process of formation of the fronts is known as frontogenesis. In contrast to the Hadley, Ferrel and polar circulations that run along north-south lines, the Walker circulation is an east-west circulation. The student is expected to: (C) explain how thermal energy transfer between the ocean and atmosphere drives surface currents, thermohaline currents, and evaporation that influence climate. The wind velocity in a tropical cyclone is much higher and it is more destructive. (i) If the surface air pressure is 1,000 mb, the air pressure at 1 km above the surface will be: (a) 700 mb (b) 1,100 mb (c) 900 mb (d) 1,300 mb.
