本文基于新设计的灌溉参数化方案,并将其耦合到区域气候模式WRF之中,利用此模式对黄河流域进行为期10年的区域气候模拟,结果显示引入灌溉之后将减小模拟的土壤湿度,感热和潜热的偏差。灌溉导致地表增加额外的水分,从而导致土壤湿度和蒸发增加,地面空气冷却,感热减小和潜热增加,同时导致行星边界层也发生变化。揭示了农业灌溉在区域气候研究中的重要性和增强对人类活动在调节陆-气-云相互作用的理解。 Based on the newly designed irrigation parameterization scheme and coupling it to the regional climate model WRF, a 10-year regional climate simulation of the Yellow River Basin is carried out. The results show that after the introduction of irrigation, the simulated soil moisture will be reduced, Sense of heat and latent heat of the deviation. Irrigation causes additional moisture to the surface, resulting in increased soil moisture and evaporation, ground air cooling, reduced sensible heat and increased latent heat, as well as changes in the planetary boundary layer. Revealed the importance of agricultural irrigation in regional climate studies and increased understanding of human activities in regulating land-air-cloud interactions.
