“…One motivation in developing coupled atmospheric and hydrological models is to improve parameterization schemes for water cycling processes, and then enhance simulating and forecasting accuracy. Some hu-man activities, e.g., reservoir impounding and regulation, groundwater extraction and irrigation, can significantly alter hydrological processes and the water cycle [98][99][100][101][102][103].…”

The past two decades have seen an intensive development in two-way coupled atmospheric and hydrological models, providing new opportunities to thoroughly understand hydrology–atmosphere coupling and improve hydrometeorological forecasting, which has not been possible before. This paper summarizes recent developments in hydrological presentation in land surface models (LSMs) and climate models, and the two-way coupling of atmospheric and hydrological models. The fully coupled models have been widely applied in identifying the impact of lateral surface and subsurface water transport in a land–atmosphere coupled system, and hydrometeorological simulations using techniques such as parameter calibration, data assimilation, and hydrology model structure revision have been used to improve the model accuracy. However, their applications still face major challenges, e.g., the complexity of hydrological parameter calibration, the lack of understanding of the physical mechanisms at high resolution, the parameterization of anthropogenic activities, and the limitations in simulation domain and period. Despite these difficulties, fully coupled atmospheric and hydrological models will gradually evolve into powerful tools to reproduce regional water cycles, offering significant potential for scientifically investigating water resources security issues affected by both climate change and human activities.

“…Studies have shown that the cooling effects of irrigation may be underestimated by global climate models due to their coarse spatial resolutions (Chen & Dirmeyer, 2020; Sorooshian et al, 2011). Irrigation datasets are required to both model and evaluate irrigation schemes and parameterizations, with information required for four key properties of irrigation: where, when, how, and how much to irrigate (Xia et al, 2022).…”

The Land surface Interactions with the Atmosphere over the Iberian Semi‐arid Environment (LIAISE) campaign was conducted in July 2021 primarily to investigate the role of irrigation in modulating the boundary layer evolution in the Catalan region of northeastern Spain. Contrasts in near‐surface meteorological parameters and boundary layer thermodynamic profiles at an irrigated and rainfed (arid) site were established during the morning transition. Evapotranspriation dominated the flux partitioning at the irrigated site (Bowen ratio of 0.07–1.1), whilst sensible heat flux dominated at the rainfed (arid) site (Bowen ratio greater than 10.0). The cumulative evapotranspiration during July 2021 was a factor of 10 greater at the irrigated site than at the rainfed (arid) site. The presence of irrigation was shown to modulate the vertical gradients of turbulence, temperature, and moisture. Irrigation is shown to have a significant effect on the development of the boundary layer including during the morning transition. The morning transition mean buoyancy flux was 2.8 times smaller at the irrigated site (1.1 m2 s−2) compared with the rainfed (arid) site (3.1 m2 s−2), with a resultant delay in the near‐surface buoyancy‐flux crossover time (30‐min to 90‐min) at the irrigated site. At the start of the morning transition (sunrise), the average screen‐level (50 m) temperature was ‐1.2 K (‐1.9 K) colder at the irrigated site relative to the rainfed (arid) site. The colder temperatures at sunrise at the irrigated site are predominately the result of colder boundary layer thermodynamic profile from the previous day. At the end of the morning transition (convective onset), temperature differences between the two sites extend through much of the boundary layer and increased in magnitude. The average screen‐level (50 m) temperature difference was ‐3.6 K (‐2.4 K) colder at the irrigated site relative to the rainfed (arid) site. There was considerable day‐to‐day variability in temperature contrasts at a regional level (‐2.4 to ‐6.0 K).This article is protected by copyright. All rights reserved.

“…Our model development builds on the offline mode of the coupled Atmospheric and Hydrological Modelling System (AHMS), developed at the University of Cologne (Jiang et al, 2020;Xia, 2019). An example of the AHMS applications to wet hydrological basins can be found in Xia et al (2022). The use of river water and groundwater for irrigation in the Yellow River Basin is expected to profoundly impact the regional hydrological processes.…”

“…The Atmospheric and Hydrological Modelling System (AHMS) is a fully coupled atmospheric and hydrological modelling system (Jiang et al, 2020;Xia, 2019;Xia et al, 2022). Specifically, AHMS couples the Weather Research and Forecasting (WRF) modelling system (Skamarock & Klemp, 2008) with the physically-based distributed regional Hydrological Model System HMS (Yu et al, 2006) through the Noah-Multiparameterziation Land Surface Model (Noah-MP; Chen & Dudhia, 2001;Niu et al, 2011).…”

“…Different from the previous work of Xia et al (2022) combined the land surface hydrological model with the Global Crop Water Model (GCWM) to study hydrological processes in the waterrich areas of China, this study aims to develop an irrigation model that applies to arid and semi-arid regions. To this end, we extend AHMS to incorporate and modify a dynamic irrigation scheme (Xu et al, 2019) in Noah-MP, allowing us to quantify the dynamic irrigation water requirements of dryland crops based on the soil moisture deficit method.…”

The coupled Atmospheric and Hydrological Modelling System (AHMS) combines a hydrological model (HMS) with the Weather Research and Forecast model (WRF) through the Noah-MP land surface scheme. This system is applied in offline mode to the hydrological processes in the Yellow River Basin which has been dramatically affected by intensive human activities over the past decades. In the earlier studies, the river water use for irrigation is often not considered, which is however an essential component of the water balance in the arid and semi-arid areas of the Yellow River Basin. Here, the channel routing model of the AHMS is extended to account for irrigation water taken from river. The irrigation water requirements are estimated based on the WATNEEDS model. AHMS is applied for the period 1979-2013 and the model results are compared with observations. It is found that for the upstream stations, the model simulated and observed streamflow are in good quantitative agreement. Comparison with the observed streamflow at the Huayuankou station near the outlet of the upper and the middle reaches of the Yellow River Basin shows that the model performance improves significantly with the consideration of irrigation. For the entire Yellow River Basin, the AHMS is found to perform well with consideration of irrigation water consumption. The progress achieved in the present work demonstrates the capacity of the AHMS for long-term hydrological simulations in the Yellow River Basin and the AHMS simulation provide a comprehensive and quantitative overview of the water resources in this important river basin.
