Numerical Study of the Seasonal Variations of the Subtropical Front and the Subtropical Countercurrent
Publisher: American Meteorological Society
Abstract: Response of the Subtropical Countercurrent and the Subtropical Front in the North Pacific Ocean to seasonally changing wind stress and thermal condition are examined using the same idealized numerical model that the author ...
Tropical Subsurface Salinity and Tritium Distributions in the Pacific: Their Differences and Formation Mechanisms
Publisher: American Meteorological Society
Abstract: While high salinity water extends to the equator in the upper thermocline of the Pacific in the Southern Hemisphere (SH), it hits the western boundary (WB) farther north of the equator in the Northern Hemisphere (NH), ...
A Numerical Investigation of the Subduction Process in Response to an Abrupt Intensification of the Westerlies
Publisher: American Meteorological Society
Abstract: A three-dimensional ocean general circulation model, forced by idealized zonal winds, is used to investigate the effect of an abrupt intensification of westerly winds on the subduction process. Four experiments are carried ...
Interannual Seesaw between the Aleutian and Icelandic Lows. Part I: Seasonal Dependence and Life Cycle
Publisher: American Meteorological Society
Abstract: The seasonal dependence and life cycle of the well-known interannual seesawlike oscillation between the intensities of the surface Aleutian and Icelandic lows (AL and IL, respectively) are investigated, based on the National ...
Dynamic and Thermodynamic Characteristics of Atmospheric Response to Anomalous Sea-Ice Extent in the Sea of Okhotsk
Publisher: American Meteorological Society
Abstract: Influence of sea-ice extent anomalies within the Sea of Okhotsk on the large-scale atmospheric circulation is investigated through an analysis of the dynamic and thermodynamic characteristics of the response in an atmospheric ...
Seasonal Variations of Precipitation Properties Associated with the Monsoon over Palau in the Western Pacific
Publisher: American Meteorological Society
Abstract: In this study, the authors focused on the seasonal variations of precipitation properties over the western Pacific, particularly those associated with the wind direction of the monsoon. An observational project over Peleliu ...
Direct Observations of Atmospheric Boundary Layer Response to SST Variations Associated with Tropical Instability Waves over the Eastern Equatorial Pacific
Publisher: American Meteorological Society
Abstract: Tropical instability waves (TIWs), with a typical wavelength of 1000 km and period of 30 days, cause the equatorial front to meander and result in SST variations on the order of 1°?2°C. Vertical soundings of temperature, ...
