Presentation Transcript

  1. Water Cycle Formulation of the hydrological cycle Equations of Hydrology Observations

  2. Formulation of the hydrological cycle

  3. Global water content 13.1x1015kg (~2.5cm) Annual mean precipitation ~1m Overturning ~40 times/year (9 days)

  4. Equations of Hydrology S=P-E-R0-Ru S- rate of storage of water P- precipitation rate (liquid and solid phase) E- evaporation rate R0- surface runoff Ru-subterranean runoff -time-averaging, -space-averaging For large areas is small, thus accurately measured semiempiric estimates measured

  5. Runoff

  6. Balance Equations for Water Wapor -amount of precipitable water [g/m2] -equation for the atmospheric branch of the hydrological cycle -areal runoff, couples land and atmospheric branches, thus Globally E=P -transport trough one parallel -vertical transport

  7. Water Wapor in the Atmosphere(Horizontal patterns)

  8. Water Wapor in the Atmosphere(Vertical patterns) More than 50 percent of the water vapor is below 850mb (90 percent below 500mb)

  9. NH: Summer-Winter 1.2cm water SH: Summer-Winter 0.7cm water Global mean water content 2.5cm

  10. Transport of Water Vapor

  11. Aerial Runoff
