The seasonal and annual climatological behavior of selected components of the hydrological cycle are presented from coupled and uncoupled configurations of the atmospheric component of the Community Climate System Model (CCSM), the Community Atmosphere Model Version 3 (CAM3). The formulations of processes that play a role in the hydrological cycle are significantly more complex when compared with earlier versions of the atmospheric model.Major features of the simulated hydrological cycle will be compared against available observational data, and the strengths and weaknesses will be discussed in the context of the fully-coupled model simulation.

“…Over the period 1976-1996, Dickson et al [2000 obtained a correlation of 0.77 from parameterized ice volume flux. Vinje [2001] found a negative correlation of -0.32 for the period 1962 -1978 and also discovered that only for certain periods is there a significant correlation between the NAO and the Arctic ice flux. Vinje [2001] sums up the situation by stating that recent Figure 1.…”

“…On the other hand, Hilmer and Jung [2000] discovered no significant correlation between Arctic sea ice export and the NAO from 1958 to 1977, but for the period 1978 -1997 the correlation increased to 0.7. Most recently, Vinje [2001] obtained a correlation of only 0.1 between the Fram Strait ice export and the NAO index from an analysis of a 50-year time series (1950 -2000) of parameterized monthly ice volume flux through Fram Strait. Hilmer and Jung [2000] found the same low correlation for the 40-year period 1958-1997.…”

A link between Fram Strait sea ice export and atmospheric planetary wave phase

[1] A link is found between the variability of Fram Strait sea ice export and the phase of zonal wave 1 in SLP for the period 1958 -1997. Previous studies have found that the link between ice export through Fram Strait and the NAO is inconsistent over time scales longer than the last two decades. Inconsistent and low correlations are also found between Fram Strait ice export and the AO index. The phase of zonal wave 1 explains 60% -70% of the simulated ice export variance after the removal of two anomalous phases in 1966 and 1967. Unlike the NAO and AO links, these high variances are consistent for both the first and second halves of the 40-year period. This consistency is attributed to the sensitivity of wave-1 phase to the presence of secondary low pressure systems in the Barents Sea that serve to drive Arctic sea ice southward through Fram Strait.

“…The Transpolar Drift is the main export route for sea ice exiting the central Arctic basin (Vinje, 2001;Pavlov et al, 2004). It transports both multi-year ice and first-year ice south through Fram Strait into the Greenland and Iceland seas (Fig.…”

“…It transports both multi-year ice and first-year ice south through Fram Strait into the Greenland and Iceland seas (Fig. 3), where the majority of the ice eventually melts (Vinje, 2001;Rigor et al, 2002). Ice formed along the Siberian Coast is transported within 3-5 years towards the Greenland Sea, whereas ice originating from the central and western Arctic Ocean needs at least 5 years to reach Fram Strait (Rigor et al, 2002).…”

a b s t r a c tWe compare and contrast the ecological impacts of atmospheric and oceanic circulation patterns on polar and sub-polar marine ecosystems. Circulation patterns differ strikingly between the north and south. Meridional circulation in the north provides connections between the sub-Arctic and Arctic despite the presence of encircling continental landmasses, whereas annular circulation patterns in the south tend to isolate Antarctic surface waters from those in the north. These differences influence fundamental aspects of the polar ecosystems from the amount, thickness and duration of sea ice, to the types of organisms, and the ecology of zooplankton, fish, seabirds and marine mammals. Meridional flows in both the North Pacific and the North Atlantic oceans transport heat, nutrients, and plankton northward into the Chukchi Sea, the Barents Sea, and the seas off the west coast of Greenland. In the North Atlantic, the advected heat warms the waters of the southern Barents Sea and, with advected nutrients and plankton, supports immense biomasses of fish, seabirds and marine mammals. On the Pacific side of the Arctic, cold waters flowing northward across the northern Bering and Chukchi seas during winter and spring limit the ability of boreal fish species to take advantage of high seasonal production there. Southward flow of cold Arctic waters into sub-Arctic regions of the North Atlantic occurs mainly through Fram Strait with less through the Barents Sea and the Canadian Archipelago. In the Pacific, the transport of Arctic waters and plankton southward through Bering Strait is minimal.In the Southern Ocean, the Antarctic Circumpolar Current and its associated fronts are barriers to the southward dispersal of plankton and pelagic fishes from sub-Antarctic waters, with the consequent evolution of Antarctic zooplankton and fish species largely occurring in isolation from those to the north. The Antarctic Circumpolar Current also disperses biota throughout the Southern Ocean, and as a result, the biota tends to be similar within a given broad latitudinal band. South of the Southern Boundary of the ACC, there is a large-scale divergence that brings nutrient-rich water to the surface. This divergence, along with more localized upwelling regions and deep vertical convection in winter, generates elevated nutrient levels throughout the Antarctic at the end of austral winter. However, such elevated nutrient levels do not support elevated phytoplankton productivity through the entire Southern Ocean, as iron concentrations are rapidly removed to limiting levels by spring blooms in deep waters. However, coastal http://dx
