Simulation performance of different planetary boundary layer schemes in WRF V4.3.1 on wind field over Sichuan Basin within "Gray zone" resolution

Weather Research and Forecasting (WRF) model was used to investigate the performance of different planetary boundary layer (PBL) parameterization schemes on simulating surface wind fields over Sichuan Basin at a spatial resolution of 0.33km. The experiment is based on multi-case studies, so 28 near-surface wind events from 2021 to 2022 were selected, and a total of 112 sensitivity simulations were carried out by employing four commonly used PBL schemes: YSU, MYJ, MYNN2, and QNSE, and compared to observations.

The mean 10 minutes observations of wind speed and direction during the study period from the Guanghan Airport are stored in one seperate txt file named OBS-28cases-every10min-10m-wind-Guanghan-Airoprt.txt.

Wind field (U10, V10) at the central point from the WRF simulations of inner domain from all the PBL simulations are investigated, which are stored in txt format (.txt), and all the results are available from the first author([e-mail]).
