为了了解灌溉对天气和气候的影响,2018年大平原灌溉试验收集了内布拉斯加州东南部灌区和非灌区的综合观测数据。利用这些观测结果,我们研究了灌溉如何影响昼夜地形产生的斜坡循环,特别是斜坡风。我们发现,在缓坡地形的上坡地区进行灌溉,可将地形引起的斜压性和相关的压力梯度力降低三分之二。这导致了下午和晚上上坡风的减少,并通过与高分辨率快速刷新操作模型的比较得到了支持,该模型没有明确考虑灌溉。此外,灌溉的存在降低了白天感热通量(与非灌溉区相比,波文比降低了40%),减弱了动量的湍流输送。灌溉对地形强迫环流的改变有可能影响大平原上的水分输送,从而影响云和降水的形成。
In order to understand the impact of irrigation on weather and climate, the 2018 Great Plains Irrigation Experiment collected comprehensive observations straddling irrigated and non‐irrigated regions in southeast Nebraska. Using these observations, we examine how irrigation affects diurnal terrain‐generated slope circulations, specifically the slope wind. We find that irrigation applied to upslope regions of gently sloping terrain reduces terrain‐induced baroclinicity and the associated pressure gradient force by up to two‐thirds. This leads to the reduction in the afternoon and evening upslope wind and is supported through comparisons to the High‐Resolution Rapid Refresh operational model, which does not explicitly account for irrigation. Additionally, the presence of irrigation decreases daytime sensible heat flux (Bowen ratio reduced 40% compared to non‐irrigated regions), weakening turbulent transport of momentum. Modifications to the terrain‐forced circulation by irrigation has the potential to affect moisture transport and thus cloud and precipitation formation over the Great Plains.
