Precipitation

Question 1

Shower(intense but short duration) type precipitation is associated with -

Intermittent(falling from time to time) type precipitation is associated with -

Continuous precipitation is associated with -

Answer 1

Convective type cloud (cumulus and cumulonimbus).

Layer type clouds.

Also layer type clouds

Question 2

Define snow and sleet:

Answer 2

Snow is simply iced precipitation. Sleet is when both rain and snow fall together.

Question 3

Drizzle falls from which cloud type? And the drop size?:

Answer 3

Cloud with little vertical development such as stratus or stratocumulus. Drizzle have a drop size of less than 0.5mm.

Question 4

Rain falls from which type of cloud?

Answer 4

Clouds which have greater vertical development, such as Nimbostratus, Stratocumulus, Cumulus and Cumulonimbus.

Question 5

Explain freezing rain:

Answer 5

Droplets of water falling from stratus or stratocumulus become super-cooled when falling through temperatures below 0 degrees and freeze on impact

Question 6

Hail falls from?

Answer 6

Cumulonimbus cloud

Question 7

Explain cloudbursts:

Answer 7

Even the largest raindrops cannot exceed 30ft/s. Therefore, if vertical up-draughts exceed 30 ft/s the raindrops remain in suspension until the convection is cut-off. The rain wall then fall resulting in heavy short duration showers.
