1
Q

Cumulus FORMATION

A
  • Convection or lifting in stable atmospheres
  • Air warms from surface heat -> cools as rises
  • Reaches dew point
  • Composed of water drops supercooled water, & ice crystals

Q

Stratus FORMATION

A
  • Cloud is equal temp (or below) environment air (heavier)
  • Orographic or Frontal lifting of stable air
  • Lifting of fog layers after sunrise
  • Composed of water droplets
  • Requires an updraft to keep it in place

Q

Altostratus FORMATION

A
  • Widespread ascent
  • Frontal lifting or convergence
  • Composed of water drops, supercooled water drops, ice crystals (more water then ice)
  • Turbulence below inversion
  • Convection or orographic lifting (in low relative humidity)
  • Composed of water drops & supercooled water drops
