摘要
针对气温为融雪计算中重要的输入变量,基于探空气温设计了三种计算方案估测高寒山区气温的垂直分布规律,以叶尔羌河流域为例,运用含融雪结构的新安江模型模拟径流,并分析了三种方案的模拟结果。结果表明,由探空气温计算的气温直减率在一定空间范围内可反映高寒区气温的垂直变化规律,可用于资料缺乏区内陆河径流模拟。
Air temperature is the important input variable for calculation snowmelt.Based on sounding temperature,three calculating schemes are designed for analyzing vertical distributions of air temperature in high-cold mountain area.Taking the Yeerqiang River Basin for an example,runoff processes are simulated by Xin anjiang hydrological model with snowmelt structure and three schemes of simulation results are analyzed.The result show that computational temperature lapse rate by sounding temperature can reflect the...
