Research Interests

Dr Thomas Birner, Dr John A. Knaff, and I are currently working on the thermal structure in tropical cyclones using COSMIC GPS Radio Occultation. We are mainly interested in the Upper Troposphere and Lower Stratosphere structures as they reveal potential feedbacks on storm development, dynamics, and intensity.
 
I previously worked with Dr William J. Randel (National Center for Atmospheric Research, NCAR) on dry layers observed in the tropical troposphere during the CONTRAST mission (CONvective TRansport of Active Species in the Tropics). A global climatology of these dry layers revealed that they are ubiquitous equartorward of the subtropical jet in the winter hemisphere. While dry features were previously thought to be associated with the downward branches of the Hadley cell, our work shows that they might be related to quasi-isentropic equatorward transport in the UTLS.
