Chapter 13 - Cloud Formation

Condensation level (P.215)

• is the same as cloud ceiling

• is the height at which water vapour condenses out as water droplets from air that is lifted and compressed

• is the height at which water vapour condenses out as water droplets from air that is lifted and warmed

• is the height at which water vapour condenses out as water droplets from air that is lifted and cooled

The type type of clouds usually associated with turbulence cloud is (P.215):

• Stratus

• Altostratus

• Cumulonimbus

• Cirrus

Orographic cloud is formed by (P.216):

• mixing of moist air above an inversion layer

• moist air being forced up a side of a mountain

• warm moist air rising due to surface heating

• cold air moving over a warm surface

The type of cloud usually associated with convection is (P.218):

• Cumulus

• Cirrus

• Altostratus

• Nimbostratus

The types of cloud usually found in front of a warm front are (P.219)

• As / Cb

• Cs / Ci

• St / Cu

• Ns / Cb

Convergence cloud forms (P.219):

• in high pressure areas and are usually Sc or St

• in low pressure areas and are usually Ns or Cs

• in high pressure areas and are usually Ci or Cs

• in low pressure areas and are usually Cu or Cb

Ice pallets falls from (P.222):

• Cb

• Cu

• As

• Ci

Hail forms due to (P.222):

• collision with supercooled water droplets

• heat from the surface

• divergence of air near the tropopause

• mixing of air above the inversion layer

Showers are always associated with (P.223):

• St

• As

• Cu

• Ci

Cirrocumulus produces (P. 223):

• Snow

• Rain

• Hail

• No precipitation
