Experiment and computational fluid dynamics simulation study on the effect of wind disturbance on the collection rate error of rainfall
Year: 2025
Type: conference-paper
Abstract: The accuracy of rainfall data directly determined the precision of hydrological analysis. However, the rain gauges were observed above the ground, and the wind turbulence around the rain gauge mouth affected the accuracy of the observation data. To explore the mechanism of the influence of wind turbulence on the accuracy of rainfall collection and provide a correction formula for this error caused by wind disturbance, the field observation experiments and the CFD (Computational Fluid Dynamics) simulations were performed to analyze the mechanism of influence of wind disturbance in rainfall observation. The experimental results showed that the rain gauge collection rate was 4.3m <0.7m
