AGU journal highlights -- Feb. 26, 2008
Date:2/26/2008

ice drift are often obscured by weather, atmospheric moisture, and surface melt effects, Kwok seeks to determine how best to fill in the 3- to 4-month annual gaps in the satellite data. He finds that summer sea ice motion can be derived reliably from AMSR-Es 18-GHz channel, which has improved spatial resolution and lower sensitivity to atmospheric moisture than other channels previously used. Comparisons with buoy drifts reveal that the data retrieved from this channel are fairly accurate. Using this channel, Kwok examines 5 years of summer ice area exchange between the Pacific and Atlantic sectors of the Arctic Ocean and finds that sea level pressure patterns during the summer of 2006 and 2007 favored the export of sea ice into the Atlantic sector.

Title: Summer sea ice motion from the 18 GHz channel of AMSR-E and the exchange of sea ice between the Pacific and Atlantic sectors

3. Subtle wind variations may spur abrupt climate change

Simulating the climate during the Last Glacial Maximum (LGM), which occurred roughly 21,000 years ago, is a major challenge for climate modeling. In particular, the Atlantic meridional overturning circulation (AMOC), which regulates climate by distributing heat to the world's oceans and involves deepwater formation in the North Atlantic, is poorly constrained in model scenarios. To characterize the AMOC during the LGM, models must accurately simulate surface winds, which facilitate horizontal and vertical mixing in the ocean. Noting that wind fields during the LGM are not well understood, Montoya and Levermann model how changes in wind strength would affect AMOC strength. By assuming that LGM
