AB: We use Atmospheric Infrared Sounder (AIRS) and in situ ozone and water vapor measurements in the tropical and subtropical upper troposphere and lower stratosphere (UT/LS) to investigate the conditions under which tropical cyclones intensify. Ozone and water vapor measurements can be used as indicators of stratosphere-troposphere exchange, which may influence tropical storm intensification through modification of the radiative balance of the UT. AIRS provides unique vertical profiles of ozone and water vapor in the UT/LS over the entire globe each day. We will perform a statistical analysis of these trace gases in the region of tropical cyclones during the intensification or de-intensification period for a number of storms starting in 2002, when the AIRS instrument began taking data. We will also use in situ aircraft trace gas measurements, when available, to observe finer scale details of tracer distributions near tropical storms.
