Presentation Transcript

  1. Conservation of Moisture The Moisture Equation

  2. Equation of State • 1st Law of Thermodynamics (Conservation of Energy) • Moisture Equation (Conservation of Moisture) • Continuity Equation (Conservation of Mass) • Equations of Motion (Conservation of Momentum) • Coming to an ATMS 251 lab near you on March 22

  3. Hydrologic Cycle – What can happen to moisture?

  4. Moisture Equation • Mathematical representation of what can happen to water in a column of the atmosphere Evapotranspiration from ground Change of moisture storage in the column Precipitation Moisture Outflow from column Moisture Inflow from atmosphere

  5. Precipitable Water • The vertical integral of the specific humidity for a column of atmosphere • Represents the upper limit to the total precipitation that may fall • Units: m (mm)

  6. Average Specific Humidity for the layer Pressure Interval Sum up the number of levels This will yield the precipitable water in units of kg/m2. To get PW in units of meters, divide by the density of water (ρw=1000 kg/m3)

  8. Moisture Advection • Of course, moisture can be transported horizontally and vertically in the atmosphere • Moisture Advection
