Changes in the Arctic Oscillation under increased 1 atmospheric greenhouse gases
13 The Arctic Oscillation (AO) under increased atmospheric concentration of greenhouse gases 14 (GHG) was studied by comparing an ensemble of simulations from 13 coupled general circulation 15 models with GHG at the pre-industrial level and at the late 20th century level, for November to 16 March. The change in the linear AO pattern as GHG increased reveals positive sea level pressure 17 (SLP) ...
متن کاملAir-mass Origin in the Arctic. Part II: Response to Increases in Greenhouse Gases
Future changes in transport from Northern Hemisphere (NH) midlatitudes into the Arctic are examined using rigorously defined air-mass fractions that partition air in theArctic according to where it last had contact with the planetary boundary layer (PBL). Boreal winter (December–February) and summer (June–August) air-mass fraction climatologies are calculated for the modeled climate of the Godd...
متن کاملAre recent Arctic ozone losses caused by increasing greenhouse gases?
[1] It has been suggested that the Arctic ozone losses observed in recent years might be a manifestation of climate change due to increasing greenhouse gases. We here offer evidence to the contrary, by focusing on the volume of polar stratospheric clouds (VPSC), a convenient proxy for polar ozone loss whose simplicity allows for easily reproducible results. First, we analyze the time series of ...
متن کاملResponse of Sea Ice to the Arctic Oscillation
Data collected by the International Arctic Buoy Programme from 1979 to 1998 are analyzed to obtain statistics of sea level pressure (SLP) and sea ice motion (SIM). The annual and seasonal mean fields agree with those obtained in previous studies of Arctic climatology. The data show a 3-hPa decrease in decadal mean SLP over the central Arctic Ocean between 1979–88 and 1989–98. This decrease in S...
متن کاملGreenhouse Gases
Examination of research into pole alternatives indicates that, without exception, studies have found that total energy requirements associated with wood materials are considerably lower than those of commonly substituted materials. The substitution of high-energy-intensive materials for low-energy-using wood materials would contribute substantially to an overall increase in carbon
