<p class="MsoNormal"><span style="font-family:'Times New Roman'">Mesoscale organized convection is a major cause of flooding in many regions worldwide. Representing organized convection has been one of the foremost challenges in climate modeling, which limits
our ability to simulate the water cycle and its future changes. The selected candidate will work with a team of PNNL scientists on advancing modeling and understanding of mesoscale organized convection. In particular, the candidate will evaluate a non-hydrostatic
global variable resolution modeling framework at spatial resolution ranging from about 4km to 50km for its ability to simulate organized convection and related processes. Combining with data analysis, the model will be used to study and contrast the different
convection types and the role of land-atmosphere interactions on convection in the U.S. Great Plains and the Amazon. The model will also be used to investigate how the structure of mesoscale organized convection and the associated extreme precipitation may
change in a warmer climate. These efforts are part of a larger project Department of Energy funded project (WACCEM) aiming at understanding how large-scale circulation features modulate regional precipitation, what controls mesoscale organized convection and
the associated precipitation, and the multiscale connections between atmospheric circulation and water cycle processes, all in the context of the changing climate. The position is for two years and renewable contingent upon performance.
