Clouds and precipitation

Question 1ExpertLevel 93

If a cloud is very dark but droplet growth is limited why will heavy rain not be certain?

AFallable drops are necessary for rainBDark clouds are always rocksCDark clouds never contain waterDCloud colour stops gravity

Question 2ExpertLevel 93

What is the correct difference in areal rainfall nature between nimbostratus and cumulonimbus?

ABoth form only cirrusBNimbostratus can give widespread steady rain and cumulonimbus local intense rainCCumulonimbus never gives precipitationDNimbostratus makes only frost

Question 3ExpertLevel 93

If collision and coalescence of small droplets are very weak in a cloud what will happen to rain formation?

ARain will immediately become heavyBAll droplets will become hailCDroplet growth will remain slow and rainfall may decreaseDCloud will become airless

Question 4ExpertLevel 93

If supercooled droplets keep freezing on ice particles in cumulonimbus which hazard will increase?

ALight drizzleBSurface dewCFogDHailstorm

Question 5ExpertLevel 93

If high cirrus clouds are followed by lower dense layered clouds which indication is more appropriate?

APossibility of an approaching weather systemBCertain earthquakeCDrying of the seaDPermanent end of clouds

Question 6ExpertLevel 93

If rainfall is very high on the windward slope of a mountain what can the long-term climate of the leeward area be like?

AAlways very rainyBRelatively dryCDominated by sea tideDWithout air

Question 7ExpertLevel 93

If a cloud has ice crystals above and liquid droplets below what vertical structure does it show?

AUniform temperatureBComplete drynessCThermal variation with heightDMarine salinity

Question 8ExpertLevel 93

If falling snowflakes partially melt and then pass through a cold layer why can precipitation identification become complex?

APrecipitation becomes waterlessBCloud disappearsCAir becomes rockDMixed or freezing forms can develop

Question 9ExpertLevel 93

If surface air has very high relative humidity why can cloud base form lower?

ALess cooling is needed to reach saturationBAir has no water vapourCHigh humidity stops condensationDClouds form only from rocks

Question 10ExpertLevel 93

If a cloud has enough moisture but very weak uplift why will heavy precipitation remain limited?

AWeak uplift may not give particles enough time to growBWeak uplift always forms hailCMoisture stops precipitationDCloud will become rock

Question 11ExpertLevel 93

In which condition is virga more likely?

ALower air is very moistBLower air is dry and falling drops evaporateCGround is floodedDCloud has no droplets

Question 12ExpertLevel 93

If cloud droplets are very tiny and coalescence is weak what result is most likely?

AHeavy rain will occur immediatelyBHail will be compulsoryCDroplets will remain suspended and precipitation will be weakDSnowfall at ground will be certain

Question 13ExpertLevel 93

In orographic rainfall if air is already dry why will rain remain limited despite increased height?

AHeight always heats airBThere is no air on mountainsCDry air always gives heavy rainDThere will not be enough water vapour for condensation

Question 14ExpertLevel 93

If precipitation particles make several up and down cycles in cumulonimbus why can hail grow?

AA new ice layer can be added in each cycleBParticles become rocks in each cycleCUp and down motion removes airDHail grows only on the ground

Question 15ExpertLevel 93

If cloud water content is same but droplets are fewer and larger how can rain chance be affected?

ARain chance may increase because droplets can become fallableBRain will be impossibleCCloud will be vapour freeDDroplets will become rocks

Question 16ExpertLevel 93

If lower air is both warm and dry how can precipitation leaving a cloud change?

AIt may melt or evaporate and reach the surface lessBIt will always become hailCIt will become rockDLower air will have no effect

Question 17ExpertLevel 93

If a convectional cloud is local but rainfall is extremely intense what is the best reason?

ALocal strong uplift and rapid droplet growthBWidespread layered upliftCComplete drynessDRain without cloud

Question 18ExpertLevel 93

If ice crystals form in a cloud and lower layers remain cold what is more likely at the ground?

ASnowfallBDrizzleCLiquid rainDSurface dew

Question 19ExpertLevel 93

If a storm cloud has rain and icy zones together which hazard can be more associated?

AComplete absence of airBOnly surface dewCHail and intense rainDOcean salinity

Question 20ExpertLevel 93

If water starts falling from a cloud but measured surface rainfall is very low which explanation is most scientific?

ARain gauge is always wrongBDroplets evaporated in lower airCCloud never contained waterDSurface became rock
