Deep convection as a source of new particles in the midlatitude upper troposhere

Creator:

Twohy, Cynthia, Clement, Charles F., Gandrud, Bruce W., Weinheimer, Andrew J., Campos, Teresa L., Baumgardner, Darrel, Brune, William H., Faloona, Ian, Sachse, Glen W., Vay, Stephanie A., and Tan, David

Abstract:

A case study of new particle formation in the region downwind of a mesoscale convective system stretching across much of the central United States is presented. Airborne measurements were made of condensation nuclei (CN), cloud particle surface area, water vapor, and other gases. CN concentrations were greatly enhanced above and...

δ¹³C record of Upper North Atlantic Deep Water during the past 2.6 million years

Creator:

Oppo, D. W., Raymo, M. E., Lohmann, G. P., Mix, Alan C., Wright, J. D., and Prell, W. L.

Abstract:

Benthic foraminiferal δ¹³C data from site 502 in the Caribbean Sea (sill depth 1800 m) indicate that throughout the past 2.6 m.y., glacial δ¹³C values in the middepth Atlantic were higher during glaciations than interglaciations. This is interpreted as indicating a greater proportion of Upper North Atlantic Deep Water (UNADW)...

Drifter observations of a cold filament off Point Arena, California, in July 1988

Creator:

Swenson, Mark S., Niiler, Pearn P., Brink, Kenneth H., and Abbott, Mark R.

Abstract:

We use the position fixes and temperature readings from 56 Tristar-II mixed-layer drifters, in conjunction with advanced very high resolution radiometer images, to provide a description of the mesoscale variability of the flows associated with cold-water filaments in the California Current system off northern California in July 1988. We find...

Seasonal and non-seasonal variability of satellite-derived surface pigment concentration in the California Current

Creator:

Strub, P. Ted, James, Corinne, Thomas, A. C., and Abbott, Mark R.

Abstract:

Satellite-derived pigment concentrations from the west coast time series (WCTS) are averaged into monthly mean fields over the California Current system (CCS) for the period July 1979 to June 1986. Errors caused by the scattering algorithm used in the WCTS are reduced by an empirical correction function, although winter values...

The utilization of Netarts Bay by juvenile chum salmon, 1984

Creator:

Wilson, C. D. and Pearcy, William G.

Abstract:

The School of Oceanography, Oregon State University, initiated a study during the spring of 1984 to investigate the utilization of Netarts Bay by juvenile churn salmon. Specific objectives the first year were to determine: 1) the relative numbers of hatchery arid wild churn salmon, 2) the nursery areas utilized by...

Quasi-Geostrophic Topographically Generated Mean Flow over the Continental Margin

Creator:

Samelson, Roger M. and Allen, J. S.

Abstract:

Observations of oppositely directed, monthly mean alongshore currents and wind stress over the continental margin off the Pacific coast of North America motivate the theoretical examination of mean flow generation by topographic lee-wave drag. We formulate a barotropic model for wind-forced shelf-slope flow over variable topography. Our central objective is...

Mixing in the Main Thermocline

Creator:

Moum, J. N. and Osborn, T. R.

Abstract:

A series of profiles of velocity microstructure along 152°E in the western North Pacific Ocean were collected in May–June 1982. Large, averaged turbulent dissipation rates, ϵ, found in the main thermocline (400 to 1000 m) were determined by a combination of large independent estimates of ϵ and a greater rate...

Internal Waves, Dynamic Instabilities, and Turbulence in the Equatorial Thermocline: An Introduction to Three Papers in this Issue

Creator:

Moum, J. N., Hebert, D., Paulson, C. A., Caldwell, D. R., McPhaden, M. J., and Peters, H.

Abstract:

Appearing in this issue of the Journal of Physical Oceanography are three papers that present new observations of a distinct, narrow band, and diurnally varying signal in temperature records obtained in the low Richardson number shear flow above the core of the equatorial undercurrent. Moored data suggest that the intrinsic...

The Generalized Inverse of a Nonlinear Quasigeostrophic Ocean Circulation Model

Creator:

Bennett, Andrew F. and Thorburn, Michael A.

Abstract:

The generalized inverse is constructed for a nonlinear, single-layer quasigeostrophic model, together with initial conditions and a finite number of interior data. With the exception of doubly Periodic boundary condition all constraints are weak. The inverse minimizes a penalty functional that is quadratic in the errors in prior estimates of...

On Intermediate Models for Barotropic Continental Shelf and Slope Flow Fields. Part II: Comparison of Numerical Model Solutions in Doubly Periodic Domains

Creator:

Barth, J. A., Allen, J. S., and Newberger, P. A.

Abstract:

As part of a program to improve understanding of the dynamics of the complicated, vigorous eddy and jet flow fields recently observed over the continental shelf and slope, we investigate the potential of intermediate models for use in both process and data assimilation studies of these flows. Intermediate models incorporate...
