Project: Quantitative analysis of mass flux parameterization using observations from the DYNAMO (Dynamics of the Madden Julian Oscillation) field program

Aditya Choukulkar is working with NOAA’s Atmospheric Remote Sensing Group and the Physical Sciences Division. Using measure­ments from the DYNAMO field program on the equatorial Indian Ocean, Choukulkar is investigating mass flux transport in shallow convection cases, which is expected to be an important mechanism in the transport of moisture from the boundary layer into the lower troposphere. “Weather forecast models are challenged to capture this process in cu­mulus parameterization schemes due to un­availability of sufficient data sets studying this process,” he says. “Our work will enable, for the first time, characterization of mass flux profiles from close to the surface up to the cloud top. This will allow us to understand the role of shallow convection in the trans­port of moisture.” In addition, by directly observing the governing variables, this study will also help gain insights on commonly used boundary layer parameterizations.
