transpiration term. The effects from the soil water content, the ability of the soil to conduct water to the roots, and even the water logging and soil water salinity can be incorporated into ω. The contribution from the vegetation type as well as its developmental stage can be incorporated into R s . The atmospheric demand (e.g., energy supply, vapor pressure deficit, and wind speed), as pioneered by Penman ( Penman 1948 ), can be incorporated into T r . In numerical modeling, K is usually

Earth’s oceans, including effects on circulation and salinity near the mouth of large rivers. For example, the thermohaline circulation is closely linked to the freshwater balance of the Arctic Ocean basin ( Driscoll and Haug, 1998 ). In semiclosed inland seas, such as the Mediterranean, circulation is strongly influenced by riverine inputs of freshwater. River discharge plays a key role in transport of dissolved and particulate materials within and from all the continents ( Ludwig and Probst, 1998

climatological-mean state of 1 January. Present-day oceanic temperature and salinity were used to initialize the ocean model. It is necessary to have the upper ocean reach a reasonable state of equilibrium to investigate interannual climate variability ( Kantha and Clayson 2000 ). In our simulations, the annual-mean SST takes approximately 10 to 20 years to reach equilibrium, which is generally consistent with previous studies ( Abe et al. 2003 ; Wohlfahrt et al. 2004 ; Kitoh 2004 ). Deep soil moisture

the model, including temperature and salinity, are configured for the North Atlantic grid using Levitus climatology. Detailed description of this model, its skill assessment, and relevant results were presented in Chaudhuri et al. (2011a , b) . A major goal of this effort was to study the mean response of the GS to representative low and high NAO condition/forcing. This model was able to realistically reproduce the GS path ( Chaudhuri et al. 2011a ) and was then used to study the impact of

may become thinner in the future, resulting in H 2 S bubbles entering the atmosphere (e.g., Humborg et al. 1997 ). Both the salinity and the potential temperature increase with depth in the Black Sea waters. Data reported in Figure 1 of Neretin and Volkov ( Neretin and Volkov 1999 ) are used in this paper. They refer to the seawater vertical temperature distribution measured on 7 November 1993 at station 4010 (43°30′N, 31°45′E; sea depth: 1910 m). Studies of the hydrophysical and hydrochemical

low salinity of small rivers draining thick, sandy soils in central Amazonia. Conversely, the accentuation of trends observed downstream seems to be due to organic matter decay, which is expected to take place in the floodplain as water slowly enters the stream channel from temporary storage. This leads to the release of CO 2 ( 13 C depleted) and nitrogenous dissolved species (NO 3 − and DON) and symmetrically to the removal of O 2 . In the model M2, outputs are adjusted by prescribing ad

with Levitus mean annual temperature and salinity, then spun up for 500 yr in a physics-only mode. Overall ecodynamics, biogeochemistry, and photochemistry were implemented simultaneously at this point. A minimum time scale often cited for approach to the upper-ocean biotic steady state is 3 yr ( Sarmiento et al. 1993 ; Moore et al. 2002 ; Chu et al. 2003 ). Results reported here are extracted from no earlier than the third full annual cycle. Although carbon monoxide is controlled within the
