Effects of Wind Stress and Wind Stress Curl Variability on Coastal Upwelling
Publisher: American Meteorological Society
Abstract: Aircraft measurements during the winter 1989 Shelf Mixed Layer Experiment (SMILE) and summer 1982 Coastal Ocean Dynamics Experiment (CODE) were used to characterize the spatial variation of the low-level wind and wind ...
Calibration of an Airborne Lyman-Alpha Hygrometer and Measurement of Water Vapor Flux Using a Thermoelectric Hygrometer
Publisher: American Meteorological Society
Abstract: An improved calibration technique for an airborne Lyman-alpha hygrometer is presented. Like previous methods, it relies upon simultaneous measurement of absolute humidity determined from a slower response hygrometer. We ...
Measurements of Momentum and Sensible Heat Fluxes Over the Open Ocean
Publisher: American Meteorological Society
Abstract: Vertical fluxes of momentum and sensible heat have been measured above the sea surface by the direct dissipation method. Measurements were made over the open ocean from the Scripps Floating Instrument Platform (FLIP) during ...
The Use of Pressure Fluctuations on the Nose of an Aircraft for Measuring Air Motion
Publisher: American Meteorological Society
Abstract: An air-motion sensing technique is described for measurement of attack and sideslip angles and dynamicpressure. The sensing probe consists of an array of five pressure holes in the standard radome of a twin-jetresearch ...
Humidity Sensitivity of Atmospheric Temperature Sensors by Salt Contamination
Publisher: American Meteorological Society
Abstract: Anomalous results concerning the micrometeorological temperature field in the boundary layer over the ocean have been obtained in many recent experiments. These include lack of an inertial-convective subrange in temperature ...
Time and Frequency Response of a Resistance-Wire Aircraft Atmospheric Temperature Sensor
Publisher: American Meteorological Society
Abstract: The heat transfer characteristics of an aircraft-mounted resistance-wire atmospheric temperature sensor are modeled to determine the time and frequency responses. The sensor element (Rosemount 102E4AL) consists of a ...
Frequency Response of a Thermistor Temperature Probe in Air
Publisher: American Meteorological Society
Abstract: An analytical study was conducted of the thermal frequency response of an atmospheric temperature probe consisting of a thermistor bead with two lead wires soldered to thin support posts. Such probes are used in aircraft ...
Improved Wind Measurements on Research Aircraft
Publisher: American Meteorological Society
Abstract: Improved techniques for measuring horizontal and vertical wind components and state variables on research aircraft are presented. They include a filtering method for correcting ground speed and position Inertial Navigation ...
The Marine Layer off Northern California: An Example of Supercritical Channel Flow
Publisher: American Meteorological Society
Abstract: During the spring and summer, northerly winds driven by the North Pacific high pressure system are prevalent over the Northern California continental shelf, only interrupted for periods of a few days, when weak or southerly ...
