CLIVAR - Western Boundary Currents
The large transfer of heat from the ocean to the atmosphere in the vicinity of western boundary currents (WBCs) has the potential to fuel intense extratropical cyclones and to impact low-frequency changes in the large-scale atmospheric circulation. The Western Boundary Current (WBC) Ocean-Atmosphere Interaction Working Group ( http://www.usclivar.org/wbc.php) was established under the auspices of the US Climate Variability program (CLIVAR; http://www.usclivar.org/) in January 2007 to focus on the contributions of Northern Hemisphere WBCs to air-sea interaction. The WBCworking group sponsored a workshop on 15-17 January 2009 in Phoenix, Arizona, with about 50 participants from the U.S., Japan, China, France, and Germany. The papers in this special collection are primarily drawn from research presented at the workshop but also include a few additional studies onWBC-related variability and review papers on frontal and basin-scale air-sea interaction. The papers are grouped by four broad themes: i) frontal scale air-sea interaction; ii) mode water formation; iii) the influence of WBCs on storms; and iv) the role of WBCs in basin-scale climate variability. The articles will be presented below as they are published, and will appear in either the Journal of Climate, Monthly Weather Review, or the Journal of Physical Oceanography.
