part II

• vapor pressure: exerted by vapor with its solid or liquid phases
• vapor pressure: determined by water vapor in atmosphere
• Vapor pressure: part of atmospheric pressure
• saturated vp= e*- max amount of water atmosphere can hold
• absolute humidity: vapor density- mass concentration of water vapor in air
• relative humidity: vp relative to saturated vp
• dew point: temp parcel must be cooled to reach saturation
• frontal: cold air comes from beneath pushing hot air up
• orographic: hits one side of mountain usually facing coast
• convection- hot air hits ground
• adiabatic cooling: no heat exchange with surrounding air
• how does climate change affect snowfall?

  snowpack decreases, runoff duration decreases, runoff duration is two weeks earlier
• climate change affects snow by: less water being available
