Statistics of Surface Layer Turbulence over the Tropical Ocean

Creator:: Leavitt, E. and Paulson, C. A.
Abstract:: Atmospheric surface layer turbulent statistics measured during the Barbados Oceanographic and Meteorological Experiment 8 and 30 m above mean sea level are presented. The budget equations of turbulent kinetic energy, humility variance and temperature variance are examined. Within discussed limitations it is concluded that production equals dissipation in the case...

Towed thermister chain observations of fronts in the subtropical North Pacific

Creator:: Samelson, Roger M. and Paulson, Clayton A.
Abstract:: A thermistor chain was towed 1400 km through the eastern North Pacific subtropical frontal zone in January 1980. The observations resolve surface layer temperature features with horizontal wavelengths of 0.2-200 km and vertical scales of 10-70 m. The dominant features, which have horizontal wavelengths of 10-100 km, amplitudes of 0.2°-1.0°C,...

A numerical study of melt ponds

Creator:: Skyllingstad, Eric D. and Paulson, Clayton A.
Abstract:: High-resolution turbulence simulations are used to examine the importance of melt pond geometry in setting pond growth rates and albedo. Modeling the circulation of water in melt ponds using large-eddy simulation shows that both convective and windforced conditions generate well-mixed ponds, suggesting that stratification is not a significant factor in...

The albedo of Arctic leads in summer

Creator:: Pegau, W. Scott and Paulson, Clayton A.
Abstract:: Leads act as windows through which solar radiation enters the upper ocean. Studies of the heat budget and ice melt require accurate parameterization of the albedo. Results from summertime measurements of albedo over leads show that under cloudy conditions the average albedo is 0.066 with a standard deviation of 0.007....

The Effect of Rainfall on the Surface Layer during a Westerly Wind Burst in the Western Equatorial Pacific

Creator:: Wijesekera, H. W., Paulson, C. A., and Huyer, A.
Abstract:: Measurements of a fresh surface anomaly (fresh lens) produced by rainfall during a westerly wind burst have been analyzed. The measurements were made in December 1992 as part of the Coupled Ocean–Atmosphere Response Experiment in the western equatorial Pacific (2°S, 156°E). Measurements included radar estimates of rainfall, upper-ocean temperature (T),...

The Structure of Near-Inertial Waves during Ocean Storms

Creator:: Qi, Hongbo, De Szoeke, Roland A., Paulson, Clayton A., and Eriksen, Charles C.
Abstract:: Current meter data from two sites were analyzed for near-inertial motions generated by storm during the ten-month period of the Ocean Storms Experiment in the northeast Pacific Ocean. The most striking feature of the inertial wave response to storms was the almost instantaneous generation of waves in the mixed layer,...

Turbulence and Internal Waves at the Equator. Part II: Details of a Single Event

Creator:: Hebert, D., Moum, J. N., Paulson, C. A., and Caldwell, D. R.
Abstract:: In the low Richardson number shear flow above the Pacific Equatorial Undercurrent, a single vertical microstructure profile intersected the overturning crest of a packet of high horizontal wavenumber waves. The observed dissipation rates within the overturning wave were so high that if they were representative of the volume-averaged rate, the...

Turbulence and Internal Waves at the Equator. Part I: Statistics from Towed Thermistors and a Microstructure Profiler

Creator:: Moum, J. N., Hebert, D., Paulson, C. A., and Caldwell, D. R.
Abstract:: High correlations between turbulent dissipation rates and high-wavenumber internal waves and the high values of turbulent dissipation associated with internal wave activity suggest that internal waves are the main direct source of mixing in the thermocline above the core of the Equatorial Undercurrent. An extensive dataset obtained using a microstructure...

Semidiurnal internal tide in JASIN: Observations and simulation

Creator:: deWitt, L. M., Levine, Murray D., Paulson, C. A., and Burt, W. V.
Abstract:: Temperature was observed in the upper 80 m by moored thermistor chains at three locations in Rockall Channel west of Scotland. Isotherms were interpolated, and a 1‐week period of exceptionally energetic tidal oscillations was analyzed. The moored array (horizontal separations ranging from 6 to 20 km) was used as an...

An Analysis of 20 Years of Meteorological and Oceanographic Data from Ocean Station N

Creator:: Dorman, Clive E., Paulson, C. A., and Quinn, W. H.
Abstract:: Meteorological and oceanographic data for Ocean Station Vessel N (30N, 14OW) are analyzed over 20 years (1951–70) and 7 years (1964–70), respectively. A rainfall estimate is constructed for the 20-year period. The yearly average rainfall is 23 cm, far less than existing estimates. Daily and seasonal variations are presented. Heat...
