“…Reager et al [24] found a net sea level sink during 2002-2014 that could directly link with the increase in GWS or TWSA. This could further be supported by our study that as GWS increases, the sea level also increases in the East Coast; however, the subsurface catchment properties can act as a particularly strong filter on climate variability [66]. The effects of catchment size on climate-hydrology relationships, the degree of damping of climate signals related to hydrodynamic properties of the aquifer, as well as the influence of human stresses must be taken into consideration.…”

Climate association between Groundwater Storage (GWS) and sea level changes have been missing from the Intergovernmental Panel on Climate Change, demanding a requisite study of their linkage and responses. Variability in the Hydrologic Unit Code—03 region, i.e., one of the major U.S. watersheds in the southeast caused by Sea Surface Temperature (SST) variability in the Pacific and Atlantic Ocean, was identified. Furthermore, the SST regions were identified to assess its relationship with GWS, sea level, precipitation, and terrestrial water storage. Temporal and spatial variability were obtained utilizing the singular value decomposition statistical method. A gridded GWS anomaly from the Gravity Recovery and Climate Experiment (GRACE) was used to understand the relationship with sea level and SST. The negative pockets of SST were negatively linked with GWS. The identification of teleconnections with groundwater may substantiate temporal patterns of groundwater variability. The results confirmed that the SST regions exhibited El Niño Southern Oscillation patterns, resulting in GWS changes. Moreover, a positive correlation between GWS and sea level was observed on the east coast in contrast to the southwestern United States. The findings highlight the importance of climate-driven changes in groundwater attributing changes in sea level. Therefore, SST could be a good predictor, possibly utilized for prior assessment of variabilities plus groundwater forecasting.

“…These high precipitation amounts mean that the Southern Alps act as “water towers” for the much drier areas to the east (Viviroli et al ., 2007), where water from the rivers originating in the Southern Alps is used intensively for electricity generation and irrigated agriculture. Just as this multi‐scale perspective is needed to understand terrestrial hydrology, precipitation delivery is also influenced by a number of interacting climate variables across different scales (Kingston et al ., 2020). For New Zealand, these include weather systems of tropical, temperate and sub‐polar origin, themselves affected by hemispheric‐scale atmospheric circulation patterns such as the Southern Annular Mode (SAM; Kidston et al ., 2009) and El Niño Southern Oscillation (ENSO; Gordon, 1986).…”

The Southern Alps in the South Island of New Zealand are one of wettest places globally, making it critical to understand the mechanisms for delivery of extreme precipitation and river flooding. Atmospheric rivers (ARs) are recognized as key causes of extreme precipitation in New Zealand, but relatively little is known about their large‐scale meteorological drivers. Here, we aim to investigate these hydroclimatological connections for five major South Island catchments located from south–north along the axis of the Southern Alps: Te Anau, Matukituki, Pūkaki, Rakaia and Waiau Toa. For each catchment, the top eight flood events over a 38‐year period are characterized. Specifically, vertically integrated horizontal water vapour transport (IVT), 500 hPa geopotential and 300 hPa winds are examined to quantify the large‐scale atmospheric drivers of flood events. The Kidson synoptic weather classification is also employed to understand better the connection of IVT to New Zealand weather patterns. Intense IVT is associated with flood events for all five catchments and, in most instances, corresponds to AR‐type events. Spatial patterns of IVT display substantial variation between flood events and catchments; however, there are some generalizable patterns. First, clear AR‐type IVT patterns dominate for all catchments (except the Waiau Toa) with AR orientation ranging from westerly to northwesterly. For the most northerly catchment (Waiau Toa), cyclonic zones of high IVT occur instead for some events. Second, AR length varies from those restricted to the Tasman Sea (~2,000 km) to those extending to the west or north of Australia. Third, northwesterly ARs are associated with the passage of a depression in the general westerly circulation, characterized in particular by the Kidson “Trough” weather type. Finally, AR orientation is associated strongly with 300 hPa winds, and in many cases to the general wave characteristics of Southern Hemisphere circulation, particularly the Zonal Wave 3 pattern.

“…Closely inter-related key issues and challenges to large-scale hydrology were identified to improve prediction of hydrological systems behavior (surface/sub-surface) on large spatial and time scales (i.e. continental -multidecadal) under changing environmental conditions (Massei et al, 2018;Kingston et al, 2020). Large-scale hydrology depends on interactions across the ocean-atmosphere-vegetation/soil/aquifer system.…”

The UNESCO FRIEND-Water program: accelerates, shares and transfers knowledge and innovation in hydrology across the world in the frame of the Intergovernmental Hydrological Program (IHP)

Abstract. The FRIEND-Water program (FWP) is the oldest and the most transverse program (i.e. Flagship Initiative) within the Hydrological Intergovernmental Program (IHP) from UNESCO. FRIEND means “Flow Regimes from International and Experimental Network Data”. The FWP is dedicated to allow large communities of hydrologists and associated disciplines to collaborate across borders on common shared data and scientific topics which are addressed through large world regions. The program has evolved in its 35 years of existence. There are 8 large regions in the world which gather tenths of hundreds of researchers, and organize events following several research topics defined according to each region priorities. The FWP is chaired by a scientific committee gathering regional coordinators and thematic experts. Each region gives its research priorities which evolve according to the projections given by the member States during the IHP council every year. The future activities of the FWP are defined by the upcoming IHP IX program and with the support of the newly created Montpellier UNESCO Category II Center ICIREWARD, acting as FWP Secretariat.
