标题：Planet Boundary Layer Parameterization in Weather Research and Forecasting (WRFv3.5): Assessment of Performance in High Spatial Resolution Simulations in Complex Topography of Mexico
其他摘要：This paper present s the application of the Weather Research and Forecasting (WRF version 3.5) with high spatial resolution (3 and 1 km) testing four Planet Boundary Layer (PBL) schemes to the complex topography of Mexico in d ifferent numerical experiments that have tried to find the best configuration. The WRF is a Numerical Weather Prediction (NWP) model giving support for weather forecasting and modeling in Chemical Transport (CTM) or Air Quality Models as CMAQ or CHIMERE. For the above, t he objectives in this work were assess the performance, the best grid parameterization , meteorological initial conditions , temporal resolution , time step and PBL schemes used in order to minimize the exec ution time and to show changes in speedup and efficiency . Mare Nostrum III supercomputer was used for the computation al processing in the cluster . The computational performance indicators were execution time, speedup and efficiency. The sensitivity analysi s was performed using the mean bias (MB) and root mean square error (RMSE) from variables obtained by WRFv3.5 such as temperature, wind - speed, sea level pressure and the METAR Veracruz airport station observations. The results show that Mellor - Yamada - Janjic ( MYJ ) scheme was better in computational parallel execution with at least 8 processors and a time step of 18 seconds. The sensitivity analyses show that time step is not a key in the accuracy of the meteorological values obtained. It is necessary c onsider the lack of data in METAR stations in Mexico.
