cloud droplets and raindrops

Cloud Droplets and Raindrops

More in Lab 7 later today

BTW, GOES = Geostationary Operational Environmental Satellite

Cloud Droplets and Raindrops

Precipitation Ladder

step 10 growth p 90 three ways to grow over 30 diameters from cloud droplet to raindrop
Step 10: Growth – p. 90Three ways to grow over 30 diameters from cloud droplet to raindrop
  • Direct deposition – “accretion”
  • Large fall faster and catch up with smaller drops – collide and “coalesce”
  • “Supercooled” water = liquid water below freezing point (down to 40 oC) spontaneously migrates to nearby ice crystals Snowflakes!
    • Complicated physics
    • Bergeron process
raindrops so many raindrops

Raindrops, so many raindrops

snowflake shapes p 96
Snowflake shapes – p. 96
  • Plates
  • Stellars
  • Columns
  • Needles
  • Spatial dendrites
  • Capped columns
  • Irregular crystals
  • Not Snow: Graupel – Sleet - Hail
solid precipitation other than snow

Solid Precipitation other than snow

Graupel(?), Sleet, Hail, Rime

graupel p 97

Graupel – p. 97

A soft granular mass of frozen cloud droplets

sleet p 97

Sleet – p. 97

Frozen drizzle, with some complications

rime p 98

Rime – p. 98

More of a “deposition” than precipitation

Some kinds of it are called “hoar frost”

Some purdy pilfered pitchers follow:

hail p 98

Hail – p. 98

Formed in updrafts in large CB clouds

Has multiple layers from partial melting and refreezing

raindrops28
Raindrops
  • Not tear-drop shaped
  • Different classification by size
    • Showers
      • From cumulonimbus or cumulus congestus
      • Up to 6 mm
    • Rain
      • From nimbostratus
      • 1 – 2 mm
    • Drizzle
      • From stratus
      • .1 - .5 mm, effectively soaking into ground
    • Mist
      • .05 - .8 mm, from stratus
      • Oregon Mist or Scotch Mist
