RISSimilarity Relationships in the Marine Atmospheric Surface Layer for Terms in the TKE and Scalar Variance Budgets
Publisher: American Meteorological Society
Abstract: Measurements of the momentum, heat, moisture, energy, and scalar variance fluxes are combined with dissipation estimates to investigate the behavior of marine surface layer turbulence. These measurements span a wide range ...
Inertial-Dissipation Air-Sea Flux Measurements: A Prototype System Using Realtime Spectral Computations
Publisher: American Meteorological Society
Abstract: A prototype system for the measurement and computation of air?sea fluxes in realtime was tested in the Humidity Exchange Over the Sea (HEXOS) main experiment, HEXMAX. The system used a sonic anemometer/thermometer for wind ...
Turbulence Sensor Dynamic Calibration Using Real-Time Spectral Computations
Publisher: American Meteorological Society
Abstract: The integration of plug-in Fast Fourier Transform (FFT) boards in data acquisition computers allows a considerable development in the dynamic calibration of turbulence sensors. The spectral transfer function of a fast and ...
Use of Spaceborne Synthetic Aperture Radar Imagery of the Sea Surface in Detecting the Presence and Structure of the Convective Marine Atmospheric Boundary Layer
Publisher: American Meteorological Society
Abstract: Two distinct backscatter regimes are seen on a European remote sensing satellite ERS-1 C-band (5.6 cm) synthetic aperture radar (SAR) image of the sea surface during a time of fair synoptic-scale weather conditions. One ...
Measurement of Temperature Spectra by a Sonic Anemometer
Publisher: American Meteorological Society
Abstract: The response of a Kaijo Denki DAT 300 ultrasonic anemometer-thermometer is analyzed with respect to temperature and vertical velocity. The effects of the emitting-receiving cycle of the transducer array on w, T, and CowT ...
Bulk Parameterization of Air–Sea Fluxes: Updates and Verification for the COARE Algorithm
Publisher: American Meteorological Society
Abstract: In 1996, version 2.5 of the Coupled Ocean?Atmosphere Response Experiment (COARE) bulk algorithm was published, and it has become one of the most frequently used algorithms in the air?sea interaction community. This paper ...
Wind Stress Vector over Ocean Waves
Publisher: American Meteorological Society
Abstract: Previous investigations of the wind stress in the marine surface layer have primarily focused on determining the stress magnitude (momentum flux) and other scalar variables (e.g., friction velocity, drag coefficient, ...
Direct Covariance Flux Estimates from Mobile Platforms at Sea*
Publisher: American Meteorological Society
Abstract: This paper describes two methods for computing direct covariance fluxes from anemometers mounted on moving platforms at sea. These methods involve the use of either a strapped-down or gyro-stabilized system that are used ...
Integrated Shipboard Measurements of the Marine Boundary Layer
Publisher: American Meteorological Society
Abstract: The NOAA Environmental Technology Laboratory air?sea interaction group and collaborators at the Woods Hole Oceanographic Institution have developed a seagoing measurement system suitable for mounting aboard ships. During ...
