ATSC Applied Quiz with Correct Answers

ATSC Applied Quiz with Correct Answers What is the scale-name for the thunderstorms discussed in the Flying Weather theme? synoptic micro gamma or delta micro alpha or beta global / planetary mesoscale Mesoscale What is the scale-name for the larger-scale warm-frontal clouds discussed in the Flying Weather and Snow-sports Weather themes? Namely, what is the scale related to the length of the warm front, not its width. global / planetary micro gamma or delta mesoscale synoptic micro alpha or beta synoptic What is the scale-name for the mountain-wake turbulence discussed in the Flying Weather theme? (Hint: mountain-wake turbulence spans a range of scales. For this answer focus on the largest size turbulent eddies associated with mountain wakes.) mesoscale micro gamma or delta micro alpha or beta synoptic global / planetary mesoscale What is the scale-name for the trade-wind portion of the Hadley cell discussed in the Sailing Weather theme? micro gamma or delta mesoscale synoptic global / planetary micro alpha or beta global / planetary What is the scale-name for the capillary waves discussed in the Sailing Weather theme? micro alpha or beta synoptic micro gamma or delta global / planetary mesoscale micro gamma or delta What is the scale-name for the anabatic clouds discussed in the Snow-sports and Flying Weather themes? micro alpha or beta global / planetary mesoscale micro gamma or delta synoptic micro alpha or beta What is the scale-name for the high-pressure regions discussed in the Sailing- and Snow-sports-Weather themes? synoptic micro alpha or beta micro gamma or delta mesoscale global / planetary synoptic If a mesoscale wind were blowing in the same direction as a synoptic scale wind, then the result would be a strong wind because they reinforce each other turbulence in the microscale called a global-scale wind impossible to determine because of the chaotic nature of the atmosphere zero (no) wind because they cancel each other a strong wind because they reinforce each other An example where a planetary-scale motion causes a micro-scale response is/are: hoar-frost growth caused by near-calm winds in a high-pressure system lenticular clouds caused by cyclone-scale winds over a mountain wind waves created by the trade winds arctic outflow caused by the polar cell circulation cold-air pooling caused by downslope winds wind waves created by the trade winds The upper half of the stratosphere could be considered a/an temperature inversion statically neutral region mesosphere stratopause statically unstable region temperature inversion Which is FALSE? A temperature inversion can trap fog below it be a favoured location for K-H waves and CAT trap air pollutants below it enable the formation of a coastally-trapped wind form in the rising air of a cyclone form in the rising air of a cyclone A katabatic wind is another name for a hurricane is another name for a chinook wind is another name for a foehn wind can form when mountain slopes cool under clear skies at night can form when the sun heats mountain slopes under clear skies can form when mountain slopes cool under clear skies at night A katabatic wind is the name of the wind that encircles Antarctica flows downslope flows upslope flows parallel to terrain contour lines because of Coriolis force flows out of cold-air pools on the valley floors flows downslope Which is FALSE? Sea fog is a type of advective fog Frontal fog is associated with evaporation of falling precipitation Arctic sea smoke is a type of steam fog Sea fog can form over warm upwelling ocean water Radiation fog forms during clear nights under calm conditions Sea fog can form over warm upwelling ocean water Which is NOT recommended during foggy conditions maintain radio silence so you can hear other boats, planes, or skiers coming make use of fog forecasts even though they are often un-reliable be vigilant because you might need to make fast evasive maneuvers rely on radar and other instruments to navigate in a boat or plane plan ahead to stay out of foggy conditions during your travels maintain radio silence so you can hear other boats, planes, or skiers coming Which statement is FALSE? Flight above the freezing-level altitude causes ice to form on aircraft wings The freezing level can be estimated from weather maps using vertical temperature interpolation The freezing level is the altitude that usually has freezing temperature above and non-freezing temperature below The freezing level can be measured using atmospheric soundings The freezing level is associated with the rain-snow line Flight above the freezing-level altitude causes ice to form on aircraft wings Which is NOT a wave phenomenon? swell billow cloud lenticular cloud wind wave banner cloud banner cloud Which is TRUE? Ocean-wave wavelengths get larger as waves approach shore Wave clouds are also known as cumulonimbus clouds Wave period is inversely proportional to wavelength, for any fixed phase speed Lee waves form like bow waves just up-wind of mountains at low altitude Mountain wave amplitude depends partly on the Froude number Mountain wave amplitude depends partly on the Froude number
