Simulation Analysis of Artificial Precipitation Enhancement Effects By Combining Gated Recurrent Unit Algorithm with Radiosonde Data
摘要
Abstract
The effectiveness of artificial precipitation enhancement is influenced by the complexity of microphysical processes of cloud and the coupled effects of multi-scale meteorological factors,making it difficult to quantitatively characterize its dynamic response mechanisms.This leads to significant discrepancies between simulated rain enhancement amounts and actual outcomes.To address this,we proposeda simulation analysis method for artificial rain enhancement that combines the gate recurrent unit algorithmwith radiosonde data.By deploying radiosondes via unmanned aerial vehicles to collect high-resolution meteorological data,the ensemble empirical mode decomposition(EEMD)method was applied to extract intrinsic mode function(IMF)components and residual components at different temporal scales,thereby characterizing meteorological features at various temporal scales.A bidirectional gate recurrent unit(BiGRU)model was constructed,leveraging its robust temporal modeling capabilities to input meteorological features at different time scales,enabling dynamic simulation and prediction of complex meteorological conditions during artificial precipitation enhancement processes.Experimental results showed that this method can effectively capture changes in precipitation after catalytic operations,with simulated precipitation curves more closely matching actual artificial precipitation curves.Additionally,under different catalyst types,dosage levels,and release altitudes,the correlation coefficients for simulated artificial precipitation enhancement effects all exceeded0.85.The simulation results of this method can provide scientific decision-making support for artificial precipitation enhancement and technical support for ecosystem restoration and sustainable water resource management in arid regions.关键词
