This is the paper for our final project in our Numerical Weather Prediction class. For this project, we analyzed model output from a Nested Regional Climate Model (NRCM), which is an adaptation of the Advanced Research WRF (ARW). The model output variables analyzed were outgoing long wave radiation (OLR) and precipitation (convective plus non-convective). The goal of this research project was to determine why errors were occurring in the model, and what could be done to correct them. In this paper, we provide some insight into why these errors occurred, particularly errors within the model which equaled or surpassed the overall mean climate error.
