Key ideas in Atmospheric Physics: The Secret Life of Clouds

  • High CCN concentrations create a larger number of smaller droplets (Twomey effect)
  • Saturation vapor pressure is lower over ice than over liquid water
  • Smaller droplets increase the total surface area for light scattering, raising reflectivity
  • Water vapor diffuses from the high-pressure liquid environment to the low-pressure ice surface
  • Smaller droplets suppress collision-coalescence, extending cloud lifetime by delaying rain
  • Liquid droplets evaporate to maintain equilibrium as the vapor is consumed by ice growth
  • How CCN concentration influences cloud albedo and precipitation timing
  • The mechanism of the Bergeron-Findeisen process in mixed-phase clouds
  • Pure water lacks the structural template to form an ice lattice at moderate sub-freezing temperatures
  • Droplets of similar size have similar terminal velocities, preventing collisions
  • Ice-nucleating particles (INPs) like mineral dust or bio-aerosols are required for heterogeneous freezing above -40°C
  • A broad distribution allows larger 'collector' drops to fall through and capture smaller droplets
  • The stability and trigger requirements of supercooled liquid water
  • Homogeneous nucleation occurs when random molecular clusters of water reach a critical stable size
  • -40°C is the physical limit where the energy barrier for ice formation is overcome by thermal fluctuations alone
  • Clouds above this altitude/temperature are composed entirely of ice regardless of aerosol content
