MET - Clouds

What does super saturated mean?

• air reaches 100% saturation without condensing

• air reaches 100% saturation and condenses

• relative humidity is approaching 100%

• saturation content is more than absolute humidity

What is deposition?

• ice to liquid

• vapour to liquid

• vapour to ice

• ice to vapour

What is the likely cloud, turbulence, water droplets when air is stable?

• Cumuliform, severe, large

• Stratiform, severe, large

• Cumuliform, light, small

• Stratiform, light, small

What is the likely cloud, turbulence, water droplets when air is unstable?

• cumuliform, light, large

• cumuliform, strong, large

• stratiform, strong, large

• stratiform, light, small

What is convective rising?

• When two air masses of different temperatures meet one is forced to rise

• When the heating of earth's surface provides rising

• When there's surface convergence as seen in a low pressure system causing air to rise

• When air is forced to rise up a mountain

How does frontal lifting produce cloud?

• Surface convergence causing air to rise

• Heating of Earth's surface plus unstable air

• Parcels of air at different temperatures meet and force one to rise

• A front moving from ocean to land is heated and causes front to rise

What does alto indicate?

• Below 7,000ft

• 7,000-17,000ft

• Above 17,000ft
