EPIC 95°W Observations of the Eastern Pacific Atmospheric Boundary Layer from the Cold Tongue to the ITCZ

Creator:: de Szoeke, Simon P. and Bretherton, Christopher S.
Abstract:: The atmospheric boundary layer (ABL) along 95°W in the eastern equatorial Pacific during boreal autumn is described using data from the East Pacific Investigation of Climate (EPIC) 2001, with an emphasis on the evolution of the thermodynamic ABL properties from the cold tongue to the cold-advection region north of the...

Variability in the Southerly Flow into the Eastern Pacific ITCZ

Creator:: de Szoeke, Simon P. and Bretherton, Christopher S.
Abstract:: During boreal summer and fall, there is a strong southerly boundary layer flow across the equator into the east Pacific intertropical convergence zone (ITCZ). The modulation of this flow on synoptic to seasonal time scales is studied using an index of meridional pressure difference between the equator and the ITCZ...

Comparison of Ceilometer, Satellite, and Synoptic Measurements of Boundary-Layer Cloudiness and the ECMWF Diagnostic Cloud Parameterization Scheme during ASTEX

Creator:: Bretherton, Christopher S., Klinker, E., Betts, A. K., and Coakley, J. A., Jr.
Abstract:: Cloud fraction is a widely used parameter for estimating the effects of boundary-layer cloud on radiative transfer. During the Atlantic Stratocumulus Transition Experiment (ASTEX) during June 1992, ceilometer and satellite-based measurements of boundary-layer cloud fraction were made in the subtropical North Atlantic, a region typified by a 1–2 km deep...

The Global S₁ Tide

Creator:: Ray, Richard D. and Egbert, Gary D.
Abstract:: The small S₁ ocean tide is caused primarily by diurnal atmospheric pressure loading. Its excitation is therefore unlike any other diurnal tide; in particular, pressure loading is maximum near the equator where the diurnal gravitational potential is zero. The global character of the S₁ tide is here determined by numerical...

Epifaunal density differences on coralline algae compared to fleshy algae in the Yachats, Oregon intertidal community

Abstract:: Ocean acidification has led to many issues regarding the decline of calcifying organisms, such as coralline algae. Acidified sea water inhibits precipitation of CaCO3 that affects the structure and growth of coralline algae. Therefore, non-calcifying algae may outcompete calcifying algae in the intertidal systems with future acidic ocean condition. Variety...
