Lapse rate, dry adiabats, moist adiabats

  1. Oct 9, 2015 #1
    1. The problem statement, all variables and given/known data
    With the drying out of Central California with global warming, the lapse rate may change from a moist adiabatic lapse rate to a dry lapse rate. Does this mean the lapse rate would decrease or increase?

    2. Relevant equations
    https://www.google.com/search?q=moi...ozE39a0yAIVTJUNCh01TA_T#imgrc=TVgSQ4ZODxnXTM:

    3. The attempt at a solution
    I can see what the difference of the slopes are. I would say that moist adiabat has a higher lapse rate than the dry diabat. Therefore if we go from Moist adiabat to Dry adiabat then the lapse rate would decrease.

    Is lapse rate quoted as ##\Delta \theta / \Delta h## or the other way around? Which is Y and which is X on the graph you are looking at?

    Sorry, do not pay attention to that picture, the lapse rate is change of altitude over the change of temperature.

    Right! thank you, so it would increase, In the dry adiabat if we go down for example 5 kilometers then t will raise to x and in the moist adiabat if we go down to 5 then t will just raise to a value that is smaller than x.

    Yes.
