Clouds and precipitation

Question 1ExpertLevel 92

If the surface is very hot but a stable air layer exists above why can convectional clouds be suppressed?

AStable layer can stop rising airBStable layer always gives heavy rainCHeat has no relation with airDStable layer turns cloud into river

Question 2ExpertLevel 92

If small droplets fall continuously in an area but visibility is not extremely low which precipitation form is likely?

ADrizzleBDense fogCHailDFrost

Question 3ExpertLevel 92

If a cloud has both small and large droplets why can larger droplets grow further?

AThey can collide with and collect smaller dropletsBThey become rocks and fallCThey are waterlessDThey always only evaporate

Question 4ExpertLevel 92

If rainfall started from a cloud but less amount reached the surface which factor could be responsible?

AEvaporation in lower airBRock hardnessCRiver bendDSea tide

Question 5ExpertLevel 92

What is the main advantage of considering both form and height in cloud classification?

AIt gives better idea of cloud type and possible weatherBIt shows rock colourCIt shows sea depthDIt decides earthquake intensity

Question 6ExpertLevel 92

If a cloud contains ice crystals and supercooled droplets which statement is most scientific?

AThis mixed cloud may support precipitation growthBThis makes precipitation impossibleCThis makes the cloud waterlessDThis creates only dust storm

Question 7ExpertLevel 92

If rain occurs sometimes in a rain shadow area why can general dryness still remain?

AOver long term leeward descending air increases drynessBSea is always above thereCHeavy rain occurs there every dayDAir has infinite moisture there

Question 8ExpertLevel 92

If falling snowflakes melt partially which precipitation form may occur?

AMixed rain and snowBOnly dry dustCOnly frostDLava rain

Question 9ExpertLevel 92

If cloud base is very low which condition of surface air is likely?

ASurface air is more humid and near saturationBSurface air is completely dryCSurface air has no vapourDSurface is like lava

Question 10ExpertLevel 92

If air warms while descending after crossing a mountain why does its rain potential decrease?

ARelative humidity decreases and condensation reducesBAir immediately becomes saturatedCVapour increases and makes rainDAir changes into rock

Question 11ExpertLevel 92

If cumulonimbus has rain below and icy regions above why can it be dangerous?

ABecause hail lightning and intense rain can developBBecause the cloud has no waterCBecause it always gives clear weatherDBecause it stays underground

Question 12ExpertLevel 92

If cloud droplets become fallable but strong updraft exists what may happen?

ASome drops may grow further before fallingBAll drops will disappear immediatelyCCloud will become soilDPrecipitation will be impossible

Question 13ExpertLevel 92

If a convectional cloud is local but rainfall is very intense what does it indicate?

ALocal strong uplift and droplet growthBWidespread calm layered cloudCComplete drynessDAbsence of front as the only cause

Question 14ExpertLevel 92

If lower air is above freezing and the ground is warm what will be the final form of falling ice crystals from a cloud?

AMore likely to become liquid rainBCertain surface frostCCertain hailDDry dust

Question 15ExpertLevel 92

If droplets do not grow in clouds yet they cover the sky how should this be understood?

ACloud cover is possible but precipitation is not necessaryBHeavy rain is certainCCloud has no waterDCovering sky is earthquake

Question 16ExpertLevel 92

If cirrus clouds are very high and fibrous what type of particles are more likely in them?

AIce crystalsBSoil particlesCLava particlesDLarge hailstones

Question 17ExpertLevel 92

If the same storm cloud has both hail and heavy rain which cloud process can be responsible?

AStrong updrafts and mixed water ice particlesBComplete drynessCOnly surface dewDRain without cloud

Question 18ExpertLevel 92

If precipitation particles form in a cloud but lower air melts or evaporates them what is the conclusion?

ASurface precipitation can differ from precipitation formed inside cloudBCloud never had waterCPrecipitation always remains same formDLower air has no effect

Question 19ExpertLevel 92

If two clouds have the same water content but one has many more condensation nuclei what result is possible?

AMore numerous smaller droplets may formBCloud will immediately become rockCVapour will disappearDEvery droplet will become large hail

Question 20ExpertLevel 92

If windward rainfall is very high in a mountain region what long-term effect may occur in nearby leeward area?

ARelatively dry climate and low rainfallBHeavy rainfall in every seasonCSea tideDPermanent absence of air
