黄淮海平原小时降水模拟:Hyetos模型应用评估
Hourly precipitation simulation in the Huang-Huai-Hai Plain:Application and evaluation of the Hyetos model
摘要
Abstract
High-resolution spatiotemporal precipitation data are critical for accurate hydrological simulations.This paper presents stochastic simulations of the hourly precipitation processes at 142 meteorological stations across the Huang-Huai-Hai Plain,using a Hyetos stochastic precipitation model that couples the Bartlett-Lewis rectangular pulse model with a daily precipitation adjustment algorithm.This model is evaluated comprehensively on its performance using metrics such as basic statistical characteristics,extreme precipitation indices,and intra-day wet-dry characteristics.Results reveal the model accurately simulates the means and standard deviations of hourly precipitation but underestimates its skewness coefficients.While it captures the intensity and frequency indices of certain extreme precipitation events,it underestimates the annual maximum 1-hour precipitation and extreme precipitation intensities.Its biases are evident in simulating intra-day wet-dry characteristics,particularly for those long-duration events.The findings would be useful to precipitation-runoff simulations in the study region.关键词
