Small bias, large errors: a dual-perspective evaluation of numerical model near-surface wind direction over beijing megacity

Accurate surface wind fields are essential for understanding moisture transport and heavy rainfall forecasts, yet the ability of kilometer-scale numerical models to capture wind direction over heterogeneous surfaces remains poorly quantified. Using the EARS1km reanalysis for the summers of 2022–2023 and hourly observat...
