Retrieval of Atmospheric Temperature Profiles from Satellite Measurements for Dynamical Forecasting
(American Meteorological Society, 1972)The method of real-time retrieval of atmospheric temperature profiles from Nimbus IV Satellite Infrared Spectrometer observations currently used in dynamical weather analysis-forecast operation is described. Each vertical ... -
Measurement of Atmospheric Temperature Profiles by Raman Backscatter
(American Meteorological Society, 1972)A technique for measuring instantaneous atmospheric temperature profiles is given. Utilizing the portion of the laser backscatter arising from the Raman rotational spectrum of N2, profiles up to 2 km with 100 m depth ... -
Temperature Gradients in Stratospheric Turbulence
(American Meteorological Society, 1972)Data obtained from U-2 HICAT flights were used to relate the magnitudes of horizontal temperature changes to flight conditions. The empirical findings can be used in estimating the effectiveness of aircraft-borne sensors ... -
An Energy Budget for Intermittent Turbulence in the Free Atmosphere
(American Meteorological Society, 1972)In order to study the physical aspects of intermittent turbulence in the free atmosphere, it is suggested that terms of an ?instantaneous? turbulent energy budget be computed from data collected by aircraft. This can be ... -
Direct Determination of Atmospheric Turbulence and Dispersion Parameters
(American Meteorological Society, 1972)A formula is presented for the frequency distribution function of wind direction, P(?), having a lateral intensity of turbulence, σv/?. A simple set-up is described which measures the relative frequency of electrical dc ... -
Optimal Choice of Parameters for the Measurement of Small-Scale Atmospheric Turbulence with an Airborne Hot-Wire Anemometer
(American Meteorological Society, 1972)The paper presents typical spectra of probe motions, turbulence, and electronic noise of an airborne hot-wire anemometer. Their relative amplitudes as a function of aircraft size and velocity, hot-wire length, and turbulence ... -
A Solution to the Paired Gill-Anemometer Response Function
(American Meteorological Society, 1972)A generalized wind vector sensor can be constructed from an orthogonally mounted Gill propeller pair. Due to the non-cosinusoidal response of each of the anemometers, simple analysis of the output leads to magnitude and ... -
Influence of Ground Roughness on Tornadoes: A Laboratory Simulation
(American Meteorological Society, 1972)observations of waterspouts and tornadoes suggest some influence of surface roughness on these phenomena. In a laboratory model of a tornado-like vortex, this influence is measured in terms of tangential and vertical ... -
Computation of the Wind by Forced Adjustment to the Height Field
(American Meteorological Society, 1972)The problem of the forced adjustment of the wind field to the height field is experimentally studied with the Mintz-Arakawa two-level atmospheric general circulation model. In all but one of the experiments, the height ... -
Correlation Functions for Wind and Geopotential on Isobaric Surfaces
(American Meteorological Society, 1972)The fact that the geostrophic wind equations describe a large fraction of the relation between wind and geopotential and that the atmosphere approximates horizontal homogeneity and is nearly isotropic leads to two differential ... -
Potential Temperature Analysis for Mountainous Terrain
(American Meteorological Society, 1972)Potential temperature (?) analysis supplies needed information that is not obtainable by other methods of graphical analysis. Terrain surface ? maps and large-scale ? cross sections are constructed by using data from weather ... -
On the Remote Sensing of Mesoscale Tropical Convection Intensity from a Geostationary Satellite
(American Meteorological Society, 1972)This paper develops an objective technique for estimating the mass and energy exchange in convection systems corresponding to altocumulus cumulogenitus and cumulonimbus intensities using measurements of the area change of ... -
Tropical Storm, Mid-Latitude Cloud-Band Connections and the Autumnal Buildup of the Planetary Circulation
(American Meteorological Society, 1972)Satellite photographs have revealed the occasional existence of broad and extensive cloud bands reaching from tropical storms northeastward into the westerlies of middle latitudes. Fourteen well-defined cases of such cloud ... -
Use of Primitive-Equation Model Output to Forecast Winter Precipitation in the Northeast Coastal Sections of the United States
(American Meteorological Society, 1972)The National Meteorology Center's operational primitive-equation multilayer model predictions of relative humidity and vertical velocity are found to be well correlated with relative frequency of observed precipitation in ... -
A Filtered-Equation Model for Operation and Research
(American Meteorological Society, 1972)A filtered-equation, pressure-coordinate, numerical prediction model is described in terms of the finite-difference formulations, and the processing strategy and its performance in an operational environment is discussed. ... -
An Intransitive Model of the Earth-Atmosphere-Ocean System
(American Meteorological Society, 1972)The earth is regarded as a whole system. BY considering the sources, sinks and flows of energy, a simple steady-state model is developed. It is found that there are five solutions, corresponding to five climates, consistent ... -
