Nan Rosenbloom


I am a Project Manager for the Climate Change and Prediction group, which is part of the Climate Change Research section within the Climate and Global Dynamics Laboratory. In this role I support multiple projects in the section, and one of my primary roles is to secure and manage the computing resources needed for scientific model simulations using the CESM model. These runs are conducted on multiple High Performance Compute platforms including the Argonne Leadership Computing Facility (ALCF), the National Energy Research Scientific Computing Center (NERSC), and the National Center for Supercomputing Applications (NCSA), as well as NCAR’s NCAR-Wyoming Supercomputing Center (NWSC).

Recent projects include orchestrating and conducting ensembles of high resolution CESM experiments to focus on the effect of climate change on the frequency, duration and distribution of atmospheric rivers, mid-latitude storm tracks and tropical cyclones. A separate project uses the low resolution CESM model to look at the effects of regionally forced ocean temperatures on climate variability and decadal predictability.
