RISShear, Strain, and Richardson Number Variations in the Thermocline. Part II: Modeling Mixing
Publisher: American Meteorological Society
Abstract: Gregg has provided observational evidence that averaged estimates of dissipation, ?, vary approximately as the square of the internal wave field energy level ? ? E2. He notes that the finding is consistent with a specific ...
Shear, Strain, and Richardson Number Variations in the Thermocline. Part I: Statistical Description
Publisher: American Meteorological Society
Abstract: Quasi-continuous depth?time observations of shear (5.5-m, 6-min resolution) and strain, (??/?z, (2-m, 2.1- min resolution) obtained from the R/P FLIP are applied to a study of Richardson number (Ri) statistics. Data were ...
On the Atmospheric Boundary Layer over the Equatorial Front
Publisher: American Meteorological Society
Abstract: This paper presents surface meteorological data and boundary layer profiles from a single meridional transect across the equator along 125°W collected during the Pan American Climate Study mooring cruise in September of ...
Toward a Statistical Description of Finescale Strain in the Thermocline
Publisher: American Meteorological Society
Abstract: The statistical properties of the oceanic finescale strain field are investigated. Strain information is derived from a set of 9000 CTD profiles from the surface to 560-m depth, obtained from the Research Platform FLIP in ...
Sensitivity of Intraseasonal Perturbations in SST to the Structure of the MJO
Publisher: American Meteorological Society
Abstract: This study demonstrates that intraseasonal perturbations in sea surface temperature (SST?) in the western Pacific warm pool is very sensitive to the structure, as well as other characteristics, of the Madden?Julian oscillation ...
Radiative Heating Errors in Naturally Ventilated Air Temperature Measurements Made from Buoys*
Publisher: American Meteorological Society
Abstract: Solar radiative heating errors in buoy-mounted, naturally ventilated air temperature sensors are examined. Data from sensors with multiplate radiation shields and collocated, fan-aspirated air temperature sensors from three ...
A New Look at Calibration and Use of Eppley Precision Infrared Radiometers. Part II: Calibration and Use of the Woods Hole Oceanographic Institution Improved Meteorology Precision Infrared Radiometer*
Publisher: American Meteorological Society
Abstract: For some years, investigators have made measurements of downwelling longwave irradiance with the Eppley Precision Infrared Radiometer (PIR), recording the values of thermopile voltage and body and dome thermistor resistances ...
Strain: Observations of the Vertical Gradient of Isopycnal Vertical Displacement
Publisher: American Meteorological Society
Abstract: In this work a profiling CTD, operated from the research platform FLIP, is used to monitor the fine-scale density field as a function of both depth and time. A sequence of 10 000 CTD profiles from the surface to 560 m is ...
Surface Buoyancy Forcing and the Mixed Layer of the Western Pacific Warm Pool: Observations and 1D Model Results
Publisher: American Meteorological Society
Abstract: The broad, shallow body of warm (>29°C) water found in the western tropical Pacific Ocean plays an important role in the coupled ocean-atmosphere dynamics and thermodynamics associated with the El Niño-Southern Oscillation ...
Moored Observations of Precipitation Temperature
Publisher: American Meteorological Society
Abstract: Direct observations of precipitation temperature were made from a surface buoy deployed for four months in the western Pacific warm pool. The observed rain droplet temperatures are equal to the wet-bulb temperature to ...
