An Operational Technique of Forecasting Thunderstorms Along the Lee Slopes of a Mountain Range
(American Meteorological Society, 1972)The lee slopes of the Rocky Mountains from Montana to New Mexico have long been recognized as prime breeding grounds for lee slope thunderstorms. A simple forecast technique is introduced which models the formation of these ... -
Mesoscale Latent Heat Release and Its Influence on Mid-Tropospheric Warming
(American Meteorological Society, 1972)A study of the effect of mesoscale latent heat release on synoptic-scale mid-tropospheric warming was made by employing a 10-level diagnostic model and the special data gathered by the National Severe Storms Laboratory. ... -
The Climatology and Prediction of the Chicago Lake Breeze
(American Meteorological Society, 1972)As part of an extensive mesoscale study of the Chicago lake breeze, ten summer months of data (1966?68) were used to compile a climatology of this phenomena and devise a simple forecasting technique. The lake breeze was ... -
Coastal Frontogenesis
(American Meteorological Society, 1972)Detailed synoptic analyses are made of mesoscale frontogenesis situations along the southeastern New England coast. Temperature gradients of 5?10C over 5?10 km along a line separating light northerly or northwesterly flow ... -
Climatic Presentations for Short-Range Forecasting Based on Event Occurrence and Reoccurrence Profiles
(American Meteorological Society, 1972)The climatology of persistency has been found to provide useful information to the short-range forecaster. This Information can be obtained directly for any given station by computer-tracing initially observed events ... -
The Use of Model Output Statistics (MOS) in Objective Weather Forecasting
(American Meteorological Society, 1972)Model Output Statistics (MOS) is an objective weather forecasting technique which consists of determining a statistical relationship between a predictand and variables forecast by a numerical model at some projection ... -
An Operational Three-Dimensional Trajectory Model
(American Meteorological Society, 1972)A numerical model is developed to compute three-dimensional trajectories from operational wind forecasts generated by the six-layer primitive equation model of the National Meteorological Center. Detailed 24-hr forecasts ... -
Scalar and Vector Partitions of the Probability Score: Part II. N-State Situation
(American Meteorological Society, 1972)Scalar and vector partitions of the probability score (PS) in N-state (N > 2) situations are described and compared. In N-state, as well as in two-state (N = 2), situations these partitions provide similar, but not equivalent ... -
Use of Numerical Guidance at the National Weather Service's National Meteorological Center
(American Meteorological Society, 1972)A brief history is given of the use of Numerical Weather Prediction guidance at NMC since 1958. A review of verification statistics shows that the impact of use of operational prediction models from the Barotropic to the ... -
Experiments in Objectively Predicting Some Atmospheric and Oceanic Variables for the Winter of 1971–72
(American Meteorological Society, 1972)The oceanic and atmospheric anomalies of the winter of 1971?72, markedly different from those Prevailing during the 1960's, are described, analyzed, and subjected to experimental objective predictions. Sea-surface temperature ... -
Predictability With and Without the Influence of Random External Forces
(American Meteorological Society, 1972)The practical limit of atmospheric predictability is a function of the uncertainties in the initial conditions, the uncertainties in the parameterization of the external forces, and the uncertainties involved with discretizing ... -

Atmospheric Tidal Measurements at 50 km from a Constant-Altitude Balloon
(American Meteorological Society, 1972)A balloon, the second In a series of high-altitude balloon flights, was launched to a record altitude of 50 km from White Sands Missile Range, N.M., on 22 September 1969. The 8.7 ? 105 cubic meter, helium-filled, zero-pressure, ... -
Examples of Economic Losses, from Hail in the United States
(American Meteorological Society, 1972)Crop-hail insurance companies, both private and governmental, insure about 15% of the national crop value, and their data represent a better source of information to evaluate economic aspects of hail loss than exist for ... -
A Technique for Accurately Locating Lightning at Close Ranges
(American Meteorological Society, 1972)A VHF lightning direction-finding technique, that can be applied to locate close lightning accurately, has been built and successfully tested. The technique, originally proposed by Oetzel and Pierce (Radio Sci., 4, 199?202, ... -
Simultaneous Measurements of Radar Reflectivity and Refractive Index Spectra in Clear Air Convection
(American Meteorological Society, 1972)Simultaneous measurements of radar reflectivity and radio refractive index at several altitudes in cleat air convection have been made. The experimental data were compared with the theoretical relationship which relates ... -
Compact Laser Radar for Remote Atmospheric Probing
(American Meteorological Society, 1972)A compact law-radar system has been developed for use on an airborne platform. Of particular interest is the use of a flashlamp-pumped dye laser as the radiation source and a plastic Fresnel lens in the receiver to collect ... -
Freezing of Freely Suspended, Supercooled Water Drops in a Large Vertical Wind Tunnel
(American Meteorological Society, 1972)The design and operation of a large vertical wind tunnel (1.8 m diameter updraft) are described, together with the associated special photographic equipment and techniques required for studies of the interactions and ... -
