Clouds and precipitation

Question 1ExpertLevel 92

If warm air slowly rises over cold air which rainfall is more likely?

AFrontal or cyclonic rainfallBOnly hailstormCOnly frostDRain without cloud

Question 2ExpertLevel 92

In which condition will it be most difficult for cloud droplets to become fallable?

ADroplets are very tiny and coalescence is weakBDroplets are large and heavyCVertical development is strongDMoisture and uplift are sufficient

Question 3ExpertLevel 92

If clouds sometimes appear over a rain shadow area but rain remains low what can be the reason?

ADroplets may not be fallable or air may be dryBThere is always sea thereCClouds are made of rockDRain has no relation with air

Question 4ExpertLevel 92

If a storm cloud has supercooled droplets aloft why does hail formation chance increase?

AThey can freeze on ice particles and form layersBThey remove all airCThey dry the cloudDThey turn into rock

Question 5ExpertLevel 92

If temperature changes sharply in lower air what difficulty can occur in identifying precipitation?

ARain snow mixed or freezing forms can changeBPrecipitation becomes waterlessCClouds disappearDAir becomes rock

Question 6ExpertLevel 92

If a cloud is dark but vertical development is weak what is the more balanced conclusion?

ADarkness may show density but storm rain is not certainBHeavy hail is certainCCloud has no waterDThe cloud is surely cirrus

Question 7ExpertLevel 92

If droplets fall from a cloud but air is strongly turbulent what effect can occur on droplet size?

ASize can change by both collision and breakupBDroplets immediately become soilCDroplets become waterlessDPrecipitation always stops

Question 8ExpertLevel 92

If moisture is high and uplift is continuous why does precipitation chance from cloud increase?

AContinuous cooling supports condensation and droplet growthBUplift always removes moistureCMoisture prevents precipitationDCloud becomes rock

Question 9ExpertLevel 92

If widespread layered clouds change into vertically developed clouds how can rainfall style change?

AFrom steady light rain toward local intense rainBFrom rain toward earthquakeCFrom cloud toward rockDFrom snow toward lava

Question 10ExpertLevel 92

If surface rainfall is low but falling water from cloud is seen on radar what explanation is possible?

ADrops evaporated in dry lower airBCloud had no waterCRadar always sees rocksDPrecipitation measurement is impossible

Question 11ExpertLevel 92

Why is it incomplete to treat clouds and precipitation as the same process?

ACloud is a group of condensed particles and precipitation occurs when they become fallableBBoth clouds and precipitation are rocksCPrecipitation has no relation with cloudsDEvery cloud immediately gives heavy rain

Question 12ExpertLevel 92

If moisture cooling droplet growth and favourable lower air occur together through the air column what is the conclusion?

ASurface precipitation chance will be strongBPrecipitation will be impossibleCCloud will be waterlessDAir will become rock

Question 13ExpertLevel 93

If updrafts keep droplets inside a cloud for a long time before falling how can precipitation nature change?

ADroplets can grow larger and give intense precipitationBDroplets will immediately become rockCCloud will become vapour freeDPrecipitation will always stop

Question 14ExpertLevel 93

If moist maritime air strikes a mountain and gives rain on the windward side what is the main cause of dryness on the leeward side?

AReturn of air to the seaBMoisture loss after rain and warming of descending airCMountain creating water vapourDAbsence of air on leeward side

Question 15ExpertLevel 93

In which situation can clouds be visible but no rainfall be measured at the ground?

ADroplets are very large and heavyBLower air is saturated and coldCFalling drops evaporate in dry lower airDGround is completely flooded

Question 16ExpertLevel 93

If ice crystals and supercooled droplets coexist in a mixed phase cloud which result is more likely for precipitation?

APrecipitation will become impossibleBCloud will become rockCWater vapour will disappearDIce crystals can grow into fallable particles

Question 17ExpertLevel 93

If the number of condensation nuclei in a cloud is very high what micro effect can occur on rain formation?

AAvailable moisture may spread into many small dropletsBEvery droplet will instantly become a large raindropCNo moisture will remain in the cloudDNuclei will remove gravity

Question 18ExpertLevel 93

If warm air slowly rises over cold air which type of rainfall is more likely?

AConvectional rainfallBFrontal or cyclonic rainfallCOrographic rainfallDOnly hailstorm

Question 19ExpertLevel 93

If a cumulus cloud grows rapidly upward and forms an anvil-like top what does it indicate?

AClear stable weatherBSurface dewCCumulonimbus and storm potentialDOnly high cirrus

Question 20ExpertLevel 93

If lower air layers are above freezing point in what form can ice crystals formed aloft reach the ground?

AFrostBMistCFogDLiquid rain
