Presentation Transcript


  1. Precipitation Formation • Cloud droplet – Rain Drop • Homogenous nucleation • Super saturation • Heterogenous nucleation • Cloud condensation nuclei • Aerosols, dust, and pollution • Sea salt

  2. 2 Primary Processes • Collision and Coalescence • Adherence and accretion through light collision • Froms progressively larger droplets • More tropical • Bergeron • Saturation vapor pressure (vp) for ice is lower than saturation vp for water • Supercooled water and freezing nuclei • Ice crystal growth through sublimation

  3. Precipitation Soundings(NWS Louisville)

  4. Precipitation Type • fun with precip type

  5. Snow to Liquid Ratios

  6. Freezing Rain Distribution(Houston and Changnon)
