ATS 656 - Tropical Meteorology & Moist Convective Systems

This course draws together concepts in the dynamics and climatology of the tropical atmosphere, as well as of significant precipitation systems across the Tropics. Specific topic areas include synoptic climatology, the dynamics of tropical flows (e.g., Kelvin waves, near Equatorial flows), convective scale dynamics, island meteorology, tropical cyclones, and the broad forces driving tropical circulations (e.g., ENSO, radiative-convective equilibrium, latent heating distributions, gregarious cloud systems). A review of key low-latitude jets, and oceanic currents, will be provided.

The goal of the class is to provide students in graduate level atmospheric science a background into tropical meteorology, emphasizing aspects of atmospheric convection across the Tropics. Exercises will focus on scales of weather between 30 N and 30 S, dynamical processes, building theoretical foundations, and real data analysis. The course will assume a strong familiarity with atmospheric thermodynamics (ATS 541) and dynamics (ATS 551) so this course's material can grow from these basic concepts.
