The changes observed over the Arctic will have critical impacts on the energy budget, and in turn feedback mechanisms may act to amplify this Arctic warming trend. This Special Issue is focused on soliciting papers that contribute to an improved understanding of atmospheric processes impacting Arctic.

2 hours ago  Subject to gravity, aerosols (or particulate matter) as well as bioaerosols become concentrated in the lower part of the troposphere that is called the planetary boundary layer ().Microbial concentrations thus usually show a vertical stratification from the bottom to the top of the troposphere with average estimated bacterial concentrations of 9 × 10 2 − 2 × 10 7 cells/m 3 in the planetary.

Figure Typical evolution of the atmospheric boundary layer (ABL) over the course of a day over land and under clear skies.

At sunrise, heating from below sets to a convective boundary layer (CBL), while at sunset heat loss to space terminates convection and creates a thin nocturnal boundary layer (NBL). [Adapted from Garratt, ]. Further investigation of the magnetic properties of Brunhes-age sediments from the Arctic Ocean has led to the hypothesis that maghemitization of detrital titanomagnetite under oxic diagenetic conditions can account for some of the observed excursional magnetization directions (Channell and Xuan, ; Xuan and Channell, ; Xuan et al., ).

The IPSL-CM5 model is built around a physical core that includes the atmosphere, land-surface, ocean and sea-ice components. It also includes biogeochemical processes through different models: stratospheric and tropospheric chemistry, aerosols, terrestrial and oceanic carbon cycle (Fig.

Accurate estimates of the exchange coefficients of momentum between the atmosphere and the ocean depend strongly on atmospheric boundary layer stability, wind shear, and the ocean surface wave field (Donelan et al., ; Smith et al., a).

This graphic shows several ocean floor features on a scale fromfeet below sea level. The following features are shown at example depths to scale, though each feature has a considerable range at which it may occur: continental shelf ( feet), continental slope (, feet), abyssal plain (>10, feet), abyssal hill (3, feet up from the abyssal plain), seamount (6, feet.

To better understand the response of the western Arctic upper ocean to late summer ice-ocean interactions, a range of surface, interior, and basal sea ice conditions were simulated in a 1-D turbulent boundary layer model.

In-ice and under-ice autonomous observations from the Marginal Ice Zone Experiment provided a complete characterization of the late melt-season sea ice and were used to.

Abstract. In the present study a non-motion-stabilized scanning Doppler lidar was operated on board of RV Polarstern in the Arctic (June ) and Antarctic (December –January ). This is the first time that such a system measured on an icebreaker in the Antarctic.

A method for a motion correction of the data in the post-processing is presented. (a) The water column. The waters of the Arctic Ocean respond quickly and in multiple ways to changing forcing parameters, including changes in freshwater input from land, modulations of ocean currents and water mass distribution, and shorter and more dispersed sea ice cover [].Of particular interest are processes in the shallowest part of the Arctic Ocean, the photic zone, where changes in.

As a result atmospheric, ocean and climate literacy programs that can connect the science with the public are necessary to help close the gap between science and the general population.

This paper addresses both the scientific and public perspectives by using the Arctic Ocean as a key illustration for understanding the ocean's role in climate. The southern boundary is a line from the southern tip of Greenland to Cape St. Charles on the coast of Labrador and the northern boundary the 66 N latitude line that joins Greenland and Baffin Island north of the Arctic Circle.

The circulation features include the West Greenland Current and the Labrador Current. The Labrador Sea is part of the. Lake-effect convective snowstorms frequently produce high-impact, hazardous winter weather conditions downwind of the North American Great Lakes.
