The hierarchy of motion from tiny gusts to giant storms is called the _____. - Correct Ans-scales of motion When the wind encounters a solid object, a whirl of air known as a(n) _____ forms on the object's downwind side. - Correct Ans-eddy If eddies form in clear air, this form of turbulence is called _____. - Correct Ans-clear air turbulence What air movements define thermal circulations? - Correct Ans-warmer air rises and colder air sinks A _____ blows air at the surface from the sea toward the land. - Correct Ans-sea breeze When the ocean air is highly concentrated with pollutants, the sea breeze front may meet relatively clean air and thus appear as a _____. - Correct Ans-smog front _____ winds can rush down elevated slopes at hurricane speeds, but most are not that intense and many are on the order of 10 knots or less. - Correct Ans-katabatic The main source of warmth for a chinook is _____. - Correct Ans-compressional heating A _____ forms as cold downdrafts along the leading edge of a thunderstorm lift dust or sand into a huge, tumbling dark cloud that may extend horizontally for over a hundred kilometers and rise vertically to the base of the thunderstorm. - Correct Ans-haboob The summer _____ of southeastern Asia, which lasts from about June through September, means wet, rainy weather (wet season) with surface winds that blow from sea to land. - Correct Ans-monsoon The general circulation of the atmosphere on the side of the earth facing the sun is known as the _____. - Correct Ans-Hadley cell Polar jet streams travel from west to east while subtropical jet streams travel from east to west. - Correct Ans-true The huge thermal anticyclone that forms over Asia because of the intense cooling of the land is called the _____. - Correct Ans-Siberian high During an _____ event, surface water near the equator becomes warmer over the central and eastern Pacific. - Correct Ans-El niño Ocean-atmosphere interactions, where a warmer or colder ocean surface can influence weather patterns in distant parts of the world, are called _____. - Correct Ans-teleconnections Single cell model - Correct Ans-air flows to and from the equator Three Cell Model - Correct Ans-Air is rising, warm and rainy. top- Polar, middle- Farrel, bottom- Hadley The serious bush fires that occur in southern california are often driven by ___ - Correct Ans-santa ana winds In single-celled models of earths general circulation of air, a large thermally driven convection cell is located in each hemisphere. Surface air flows - Correct Ans-Equatorward Describe Thermal Circulation - Correct Ans-when there are air circulations that are brought on by changes in temperature. Describe thermal highs and lows - Correct Ans-regions of surface atmospheric pressure that are created as thr atmosphere either cools or winds. Descrribe chinook winds - Correct Ans-Dry, warm winds that occur when strong westerly winds aloft flow over a north-south-trending mountain range, such as the rockies and cascades. List the scales of atmospheric motion from largest to smallest. - Correct Ans-1. Global scale 2. Synoptic scale 3. Mesoscale 4. Microscale Give an example of global scale - Correct Ans-Polar jet streams and subtropical highs Give an example of the synoptic scale - Correct Ans-mid-latitude cyclones, hurricanes and fronts Give an example of the mesoscale - Correct Ans-thunderstorms, differential heating boundaires. Give an example of microscale - Correct Ans-tornadoes, rainbows, convective updraft & downdraft what is the ITCZ? - Correct Ans-The intertropical convergence zone. Clods, thunderstorms and rain occur here. Where is the ITCZ found? - Correct Ans-near the equator. Solid bands of clouds from east and toward the equator. How does ITCZ affect the cities of Kano and Lagos? - Correct Ans-Kano: Less rainfall Lagos: more rainfall If eddies form in clear air, this form of turbulence is called _____. - Correct Ans-clear air turbulence
