Evaluation of the aerosol indirect effect in marine stratocumulus clouds : droplet number, size, liquid water path, and radiative impact

Creator:: Twohy, Cynthia, Petters, Markus D., Snider, Jefferson R., Stevens, Bjorn, Tahnk, William, Wetzel, Melanie, Russell, Lynn, and Burnet, Frédéric
Abstract:: Data from nine stratocumulus clouds in the northeastern Pacific Ocean were analyzed to determine the effect of aerosol particles on cloud microphysical and radiative properties. Seven nighttime and two daytime cases were included. The number concentration of below-cloud aerosol particles (> 0.10 μm diameter) was highly correlated with cloud droplet...

Eddy properties in the California Current System

Creator:: Kurian, Jaison, Colas, Francois, Capet, Xavier, McWilliams, James C., and Chelton, Dudley B.
Abstract:: Eddy detection and tracking algorithms are applied to both satellite altimetry and a high‐resolution (dx = 5 km) climatological model solution of the U.S. West Coast to study the properties of surface and undercurrent eddies in the California Current System. Eddy properties show remarkable similarity in space and time, and...

Seasonal and interannual variability of satellite-derived chlorophyll pigment, surface height, and temperature off Baja California

Creator:: Espinosa-Carreon, T. Leticia, Strub, P. Ted, Beier, Emilio, Ocampo-Torres, Francisco, and Gaxiola-Castro, Gilberto
Abstract:: Mean fields, seasonal cycles, and interannual variability are examined for fields of satellite-derived chlorophyll pigment concentrations (CHL), sea surface height (SSH), and sea surface temperature (SST) during 1997–2002. The analyses help to identify three dynamic regions: an upwelling zone next to the coast, the Ensenada Front in the north, and...

Seasonal cycles of currents, temperatures, winds, and sea level over the northeast pacific continental shelf: 35°N to 48°N

Creator:: Strub, P. Ted, Allen, John S., Huyer, Adriana, 1945-, Smith, Robert L. (Robert Lloyd), 1935-, and Beardsley, R. C.
Abstract:: Seasonal cycles of coastal wind stress, adjusted sea level (ASL), shelf currents, and water temperatures off the west coast of North America (35°N to 48°N) are estimated by fitting annual and semiannual harmonics to data from 1981-1983. Longer records (9-34 years) of monthly ASL indicate that these two harmonics adequately...

Near-surface trajectories off central and southern California

Creator:: Winant, C. D., Alden, D. J., Dever, Edward P., Edwards, K. A., and Hendershott, M. C.
Abstract:: The near-surface circulation in the Santa Barbara Channel and off the coast of central and southern California is described based on 20 releases of drifters drogued 1 m beneath the surface from 12 sites within the channel at bimonthly intervals. This description includes small-scale features of the circulation which are...

Seasonal and interannual variablity of pigment concentrations across a California Current frontal zone

Creator:: Thomas, A. C. and Strub, P. Ted
Abstract:: Previously published physical and biological data document a zonally oriented frontal region within the California Current system separating colder and more eutrophic water north of ≈33°N from warmer; more stratified, and oligotrophic water farther to the south. Satellite images of phytoplankton pigment from the coastal zone color scanner from 1979-1983...

Effects of mesoscale processes on phytoplankton chlorophyll off Baja California

Creator:: T. Leticia Espinosa-Carreon, T. Leticia, Gaxiola-Castro, Gilberto, Beier, Emilio, Strub, P. Ted, and Kurczyn, J. A.
Abstract:: Using satellite sea surface height (SSH) and chlorophyll (CHL), the year 2000 is analyzed to characterize the effects of mesoscale circulation patterns on phytoplankton spatial variability in the California Current (CC) off Baja California. Satellite data are combined with and compared to in situ field measurements (chlorophyll-a and hydrographic variables)...

Spatial and temporal characteristics of the mesoscale circulation of the California Current from eddy-resolving moored and shipboard measurements

Abstract:: Moored observations of currents and temperatures made in the upper 600 m on eddy-resolving scales over a 2-year period are used to examine the spatial and temporal characteristics of the California Current mesoscale circulation. The observations were made at three principal longitudes: 124°W, 126°W, and 128°W in the vicinity of...

Abstract:: In summer 1988, we made repeated mesoscale surveys of a grid extending 200 km offshore between 37°N and 39°N in the coastal transition zone off northern California, obtaining continuous acoustic Doppler current profiler data and conductivity-temperature-depth data at standard stations 25 km apart on alongshore sections 40 km apart.

Characteristic patterns of shelf circulation at the boundary between central and southern California

Creator:: Winant, C. D., Dever, Edward P., and Hendershott, M. C.
Abstract:: The coastal circulation in the Santa Barbara Channel (SBC) and the southern central California shelf is described in terms of three characteristic flow patterns. The upwelling pattern consists of a prevailing equatorward flow at the surface and at 45 m depth, except in the area immediately adjacent to the mainland...
