“…Over the past 30 years, the Arctic freshwater cycle intensified as reflected by changes in snow cover (Bring et al, 2016), evapotranspiration from terrestrial vegetation (Bring et al, 2016), and precipitation (Vihma et al, 2016). It resulted in an increase of the freshwater discharge from North American and Eurasian rivers by ∼ 2.6 and ∼ 3.1 % per decade, respectively (Holmes et al, 2015).…”

Abstract. Future climate warming of the Arctic could potentially enhance the load of terrigenous dissolved organic carbon (tDOC) of Arctic rivers due to increased carbon mobilization within watersheds. A greater flux of tDOC might impact the biogeochemical processes of the coastal Arctic Ocean (AO) and ultimately its capacity to absorb atmospheric CO 2 . In this study, we show that sea-surface tDOC concentrations simulated by a physical-biogeochemical coupled model in the Canadian Beaufort Sea for 2003-2011 compare favorably with estimates retrieved by satellite imagery. Our results suggest that, over spring-summer, tDOC of riverine origin contributes to 35 % of primary production and that an equivalent of ∼ 10 % of tDOC is exported westwards with the potential of fueling the biological production of the eastern Alaskan nearshore waters. The combination of model and satellite data provides promising results to extend this work to the entire AO so as to quantify, in conjunction with in situ data, the expected changes in tDOC fluxes and their potential impact on the AO biogeochemistry at basin scale.

“…changes in heat and moisture fluxes in the Arctic; Tjernström et al, 2015;Ding et al, 2017) factors. Among these effects, change in moisture transport has emerged as one of the most important with respect to the greenhouse effect (Koenigk et al, 2013;Graversen and Burtu, 2016;Vihma et al, 2016), and is related to SIE decline through hydrological mechanisms such as changes in Arctic river discharges (Zhang et al, 2012), radiative mechanisms such as anomalous downward longwave radiation at the surface (Woods et al, 2013;Park et al, 2015a;Mortin et al, 2016;Woods and Caballero, 2016;Lee et al, 2017), or meteorological mechanisms such as changes in the frequency and L. Gimeno-Sotelo et al: A new pattern of the moisture transport for precipitation intensity of cyclones crossing the Arctic (Rinke et al, 2017). Because the effects of enhanced moisture transport on Arctic ice are diverse, there is no direct relationship between enhanced transport and SIE decline.…”

A new pattern of the moisture transport for precipitation related to the drastic decline in Arctic sea ice extent

Abstract. In this study we use the term moisture transport for precipitation for a target region as the moisture coming to this region from its major moisture sources resulting in precipitation over the target region (MTP). We have identified changes in the pattern of moisture transport for precipitation over the Arctic region, the Arctic Ocean, and its 13 main subdomains concurrent with the major sea ice decline that occurred in 2003. The pattern consists of a general decrease in moisture transport in summer and enhanced moisture transport in autumn and early winter, with different contributions depending on the moisture source and ocean subregion. The pattern is statistically significant and consistent with changes in the vertically integrated moisture fluxes and frequency of circulation types. The results of this paper also reveal that the assumed and partially documented enhanced poleward moisture transport from lower latitudes as a consequence of increased moisture from climate change seems to be less simple and constant than typically recognised in relation to enhanced Arctic precipitation throughout the year in the present climate.

“…Some of these process cascades have been posited in conceptual models that attempt to articulate the nature of pathways that connect atmosphere and ocean processes to hydrological variability in general (Bhagwit, 2014;Hannah et al, 2014;Kingston et al 2006;Vihma et al, 2016). Within this cascade framework and from a broad hydroclimatological perspective, of particular interest is the role of modes of climatic variability, which can be generally defined as quasi-periodic variations in ocean and atmospheric circulation patterns that possess an oscillatory behaviour, and their links with hydrological variability.…”

Hydroclimatology is an expansive discipline largely concerned with understanding the workings of the hydrological cycle in a climate context. Acknowledging this, and given the burgeoning interest in the relation between climate and water in the context of working towards an improved understanding of the impacts of climatic variability on water resources this progress report turns its attention to the connection between large scale modes of climatic variability and hydrological variability in streams, lakes and groundwater. A survey of the recent literature finds a plethora of teleconnection indices have been employed in the analysis of hydrological variability. Indices representing modes of climatic variability such as El Nino Southern Oscillation, the North Atlantic Oscillation, the Pacific North America pattern, the Pacific Decadal Oscillation and Atlantic Meridional Oscillation dominate the literature on climatic and hydrological variability. While examples of discernible signals of modes of climatic variability in stream flow and lake and groundwater level time series abound, the associations between periodic to quasi-period oscillations in atmospheric/ocean circulation patterns and variability within the terrestrial branch of the hydrological are far from simple being both monotonic (linear and non-linear) and non-monotonic and also conditional on period of analysis, season and geographic region. While there has been considerable progress over the last five years in revealing the climate mechanisms that underlie the links between climatic and hydrological variability a bothering feature of the literature is how climatic and hydrological variability is often viewed through a purely statistical lens with little attention given to diagnosing the relationship in terms of atmosphere and ocean physics and dynamics. Consequently significant progress remains to be made in obtaining a satisfactory hydroclimatological understanding of stream flow, lake and groundwater variability especially, if hydroclimatological knowledge is to be fully integrated into water resource management and planning.3
