The successful candidate will join a strong team of research scientists already in place at NRL and partner institutions for this new project that builds upon NRL’s institutional expertise in high-altitude atmospheric model development for new and improved operational environmental prediction capabilities for the globally deployed Navy.<o:p></o:p></span></p><p class=MsoNormal style='text-align:justify'><span style='font-family:"Arial",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal style='text-align:justify'><span style='font-family:"Arial",sans-serif'>The new atmospheric model will be based on an emerging Navy dynamical core that solves the deep-atmosphere nonhydrostatic equations on the sphere using spectral element (SE) methods. The candidate will work primarily with a group at NRL DC developing new upper-atmospheric (mesospheric and thermospheric) components of the model, including dynamics and physical parameterizations that respond to solar and geomagnetic forcings. As model development proceeds, the candidate will conduct high-resolution model experiments on massively parallel high-performance computers to test and refine new features that help the team achieve specific project goals and milestones. In the process, the candidate may also collaborate with other project research teams located at NRL DC and elsewhere, focusing on the model’s lower altitudes, high-altitude data assimilation capabilities, and physical coupling to ionospheric models.<o:p></o:p></span></p><p class=MsoNormal style='text-align:justify'><span style='font-family:"Arial",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal style='text-align:justify'><span style='font-family:"Arial",sans-serif'>We seek a self-motivated candidate eager to study upper-atmospheric dynamics and physics relevant to short-term prediction, to develop efficient algorithms of these processes, and then to integrate them as new computer code within the evolving infrastructure of the new model. A Ph.D. in atmospheric science, computational fluid dynamics, physics, or a related discipline, is therefore preferred. Ability and willingness to work in the environment of a large, diverse and geographically distributed team, to achieve collective team goals and deliver specific monthly, quarterly and annual reporting milestones, are essential. Strong programming skills will also be required in working with a complex modern highly-scalable Fortran code using up to 1 million processors per run.
