A Simple Model of Intraseasonal Oscillations

This paper seeks to get at the essence of what make slow (40-50) day weather in the tropics by simplifying the governing equations in a way that makes them solvable with pencil and paper. Specifically, the authors present a new model of linear equatorially trapped disturbances to a moist convecting atmosphere as a possible theory for some of the observed intra-seasonal variability of the tropics. It differs from previous similar models in exploring WISHE‐type (and possibly radiative) destabilization of moisture modes.
