Open MS or PhD Position

Graduate Research Assistantship (Master or Ph.D.) in tropical meteorology and S2S prediction at OU School of Meteorology 

The School of Meteorology at the University of Oklahoma (OU) seeks a Master or Ph.D. student to conduct NOAA-funded research that will investigate the processes and subseasonal-to-seasonal (S2S) prediction skills of the diurnal cycle and the Madden-Julian Oscillation over the Maritime Continent. This project will utilize model forecasts, satellite, and observational data collected during the Years of Maritime Continent field campaign to understand the processes influencing the prediction skills of the diurnal cycle and the Madden-Julian Oscillation over the Maritime Continent. The student will work within the research groups led by Dr. Naoko Sakaeda and Dr. James Ruppert at OU and in collaboration with Dr. Giuseppe Torri at the University of Hawaii. We welcome applications for admissions in Spring, Summer, or Fall 2023. 

Panels a-b) Illustration of the interactions between the diurnal cycle and the MJO. Diurnal amplitude of rainfall (mm/hr, shaded) over the island strengthens prior to the arrival of MJO convective envelope (black solid contours showing MJO-filtered OLR). Panels c-d) Schematic illustration of the changes in the environmental condition and diurnal behavior at the same states of the MJO as in (a-b). The project will investigate the impact of these interactions between the diurnal cycle and the MJO on S2S prediction skills.
