In this laboratory course, students simulate the atmosphere using a numerical weather prediction model (WRF) and explore the physical and numerical basis of the system of equations that underpin numerical weather prediction models. In addition to developing technical skills with WRF and visualizing its output with python, students explore applications of numerical modeling of the atmosphere, such as land-sea breezes, hurricanes, mesoscale convective systems, and the daily cycle of the boundary layer. Recommended prerequisite: Experience with computer science and data visualization such as ATOC 4815 and some experience with Unix/Linux. Recommended restriction: Junior or Senior class standing. Previously offered as a special topics course. Same as ATOC 5875.
