Abstract: Methods of optimizing the Lovejoy and Austin technique to delineate areas of precipitation using visible and infrared satellite data are investigated. The technique involves training the satellite data by correlation with ...

Abstract: The neutral Ekman boundary layer is known to be dynamically unstable to infinitesimal perturbations under typical geophysical conditions. This paper discusses this instability to two-dimensional, simple-harmonic perturbations, ...

Abstract: The equations of motion for a neutrally buoyant fluid are solved to produce an equilibrium flow consisting of a modified Ekman spiral mean flow plus a helical secondary flow. By considering the secondary flow to be a finite ...

Abstract: A method of determining surface pressures in oceanic storm systems using ERS-1 scatterometer data is employed to determine the lowest pressures in 25 storms. This method uses the surface winds as a lower boundary condition ...

Abstract: A three-dimensional hot-film probe, a Vector Vane, and an Aerovane were used to measure the mean wind speed and turbulence structure in the atmospheric surface layer at a location on the south shore of Long Island. A ...

Abstract: An operational planetary boundary layer model (Brown, 1974,1978, 1981) for determining surface winds and stress from free-stream flow has been modified for the marine layer by including surface roughness feedback, variable ...

Abstract: The relationship between precipitation and infrared and visible satellite data is investigated in the vicinity of the United Kingdom. The investigation uses histograms of Meteosat data, built up from many half-hourly fields, ...

Abstract: A detailed evaluation of snow water equivalent (SWE) and snow cover extent (SCE) derived using the combined Scanning Multichannel Microwave Radiometer (SMMR) and Special Sensor Microwave Imager (SSM/I) brightness temperature ...

Abstract: A generalized relationship is derived which relates an arbitrary horizontal wind field and the Doppler velocity field that results from its observation with a single horizontally directed radar. The relationship shows ...
