Recently, artificial intelligence-based models for forecasting global weather have been rapidly developed. Most of the global models are trained on reanalysis datasets with a spatial resolution of 0.25◦ × 0.25◦. However, study on artificial intelligence-based limited area weather forecasting models is still limited. In this study, an artificial intelligence-based limited area weather forecasting model (YingLong) is developed. YingLong utilizes a parallel structure of global and local blocks to capture multiscale meteorological features. Its predictability on surface temperature, humidity and wind speed is comparable to the predictability of the dynamical limited area model WRF-ARW, but with a much faster running speed. YingLong is also applied to investigate the issues related to the lateral boundary condition of artificial intelligence-based limited area models. The difference between artificial intelligence-based limited area models and dynamical limited area models is also discussed.
