Humidity-Condensation and deposition decrease absolute humidity.-Evaporation and sublimation increase absolute humidity.i. Relative Humidity (RH): Varies predictably throughout the day because temperature varies predictably.ii. Dew Point Temperature (DPT): For an air parcel it is the temperature at which it reaches the SSH (saturation specific humidity).-Air temperature is always above the DPT unless RH=100%, when AT=DPTiii. Dew and Frostform when there is a clear night following a day with high RH.-Dew= condensation, Frost= deposition-When the temperature is less than 32 degrees Fahrenheit frost forms, and the opposite for dew.II. Air Parcel: As an air parcel moves up or down through the troposphere, its temperature changes predictably because air pressure changes.These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.-If a parcel of air rises up far enough it will cool to its DPT and clouds and possibly precipitation will form.III. Upliftconsistently happens in specific contexts.i. Orographic Upliftproduces precipitation patterns around mountains.-Rain shadow is the dry area on the leeward side of a mountain.-Mid latitude rain shadows are on the East side of mountains. It’s the opposite for tropical latitudes.ii. Other forms of uplift produce weatheri. Subtropical= monsoon, convective uplift, and thermal lowsii. Mid latitude= cyclonesiii. Tropical=
