Recent changes in the Arctic region climate Wanishsakpong et al. Changes in streamflow discharge Mendoza et al. An improved understanding of hydrological change is necessary to more effectively adapt and mitigate the potential impacts of climate change; however, given the complexity of the environment and the uncertainty associated with climate projection, this has represented a great scientific challenge. Climate projections from global circulation models GCMs agree on a warmer and wetter Arctic by the end of the century Kattsov et al. Because of problems in GCM representations of regional or local surface weather, higher-resolution tens of kilometers regional climate models RCMs are used to dynamically downscale GCMs; however, large-scale RCMs still fail to represent surface weather, particularly precipitation in areas with complex topography, deep convection, or extreme events Prein et al. Downscaling techniques are classified into statistical and dynamical approaches, the former using empirical relationships between observed and simulated climate and the latter requiring the implementation of a high-resolution climate model Maraun et al.
Special issue: Water, ecosystem, cryosphere, and climate data from the interior Data description paper 19 Mar Cold region hydrology is very sensitive to the impacts of climate warming. Impacts of warming over recent decades in western Canada include glacier retreat, permafrost thaw, and changing patterns of precipitation, with an increased proportion of winter precipitation falling as rainfall and shorter durations of snow cover, as well as consequent changes in flow regimes. Future warming is expected to continue along these lines.
Wetlands are globally important ecosystems that provide critical services for natural communities and human society. Montane wetland ecosystems are expected to be among the most sensitive to changing climate, as their persistence depends on factors directly influenced by climate e. Despite their importance and climate sensitivity, wetlands tend to be understudied due to a lack of tools and data relative to what is available for other ecosystem types. Here, we develop and demonstrate a new method for projecting climate-induced hydrologic changes in montane wetlands. Using observed wetland water levels and soil moisture simulated by the physically based Variable Infiltration Capacity VIC hydrologic model, we developed site-specific regression models relating soil moisture to observed wetland water levels to simulate the hydrologic behavior of four types of montane wetlands ephemeral, intermediate, perennial, permanent wetlands in the U. Pacific Northwest.
Climate change has significant implications on water resources and freshwater ecosystems Eum et al. Regional climate models RCMs and macroscale hydrologic models MHMs are common approaches to investigate the effects of projected climate changes on local hydrological regimes. RCMs are able to simulate detailed regional atmospheric and terrestrial processes Denis et al. The Athabasca River is the longest undammed river in the Canadian Prairies, and the potential effects of climate change on its hydrological cycles have been implicated for water scarcities, wild fires, flooding, and droughts Cheng et al. Further, annual flows of the Athabasca River have been shown to be linked with historic climate conditions across this region, a trend that is expected to continue into the future Edwards et al.
Journal of Water and Climate Change 1 March ; 10 1 : 63— The changing climate has raised significant concerns for water resources, especially on a watershed scale. In this study, the downscaled global circulation model GCM products were further bias corrected and evaluated for the period of — The results of this study show: 1 the Parameter—elevation Regressions on Independent Slopes Model PRISM products offer a reliable replacement for limited observations for bias correction using quantile mapping QM technique; 2 average increases of 2. For management of local water resources, this study provides a better understanding of variations in the streamflow rate and timing to a potential climate change in the study area as well as corresponding uncertainties in the estimation processes. Global water circulation makes atmosphere and hydrology closely interact with fluxes of water and energy, which has immediate and long-term effects on water systems.
Assessment of climate change impacts on water resources of the Purus Basin in the southwestern Amazon. Knowledge about water resources is critical for climate adaptation in face of long-term changes and more frequent extreme events occurrence. During the major droughts of and , a large epicenter was located in the southwestern Amazon over the Purus River Basin. In this sense, we conducted a hydrological simulation in this basin to assess the climate change impacts on its water resources throughout the 21st century.
Только туда ей и оставалось идти в наглухо запертом помещении. Поднявшись по ступенькам, она обнаружила, что дверь в кабинет шефа открыта, поскольку электронный замок без электропитания бесполезен. Она вошла. - Коммандер? - позвала Сьюзан. Свет внутри исходил лишь от светящихся компьютерных мониторов Стратмора. - Коммандер! - повторила .
Постарайтесь пройти по нему до конца. Сьюзан вздохнула: - Программа принимает ключ только в цифровой форме. Мне кажется, что тут содержится некий намек на то, что это за цифра. В тексте названы Хиросима и Нагасаки, города, разрушенные атомными бомбами. Может быть, ключ связан с количеством человеческих жертв, оценочной суммой нанесенного ущерба в долларах… - Она замолчала, снова вчитываясь в текст.
Уберите пробелы, - твердо сказал Дэвид. - Дэвид? - сказала Сьюзан. - Ты, наверное, не понял. Эти группы из четырех знаков… - Уберите пробелы, - повторил. Сьюзан колебалась недолго, потом кивнула Соши.
