  1. Earth2Class Workshops for Teachers Lamont-Doherty Earth Observatory “Hydrology” Dr. Michael J. Passow Guest Scientist: Dr. Upmanu Lall May 12, 2001

  2. Hydrology involves the study of water as it moves through the • Atmospheric system • Oceanic system • Freshwater system • Groundwater system • Cryosphere (“frozen system”)

  3. We often summarize the complex transfer of matter and energy as the “Water Cycle” http://www.chias.org/www/edu/mitc/wkshp/ocean/oceans.html

  4. For obvious reasons, we tend to focus on the more visible aspects of the Water Cycle • Precipitation in all its various forms: rain, drizzle, thunderstorm, mist, snow, blizzard, etc. • Also, flooding and drought focus attention on hydrology http://www.usatoday.com/weather/wtsm5.htm

  5. Occasionally we think about other aspects of the Water Cycle • Influence on landscapes, such as karst topopgraphy • Transpiration from plants • Groundwater contaminants • http://www.gsfc.nasa.gov/GSFC/EARTH/atmos/ozone.htm

  6. EVAPORATION, CONDENSATION– G   L LATENT HEAT OF VAPORIZATION MELTING, FREEZING– S   L LATENT HEAT OF FUSION SUBLIMATION, DEPOSITION— S   G
