A Survey of the Use of National Weather Service Forecasts by Television Weather Forecasters in the United States
(American Meteorological Society, 1986)This investigation was undertaken to determine how different the weather forecasts of telecasters are from those of the National Weather Service for the same areas and times, and the sources of information telecasters use ... -
Mesoscale Features of the Michigan Land Breeze Using PAM II Temperature Data
(American Meteorological Society, 1986)During the period 16?20 December 1983, the northern United States was enduring a record-breaking cold air outbreak. The cold air brought temperatures as low as ?40°C to some areas while bringing considerable lake-effect ... -
Severe Thunderstorm Forecasting: A Historical Perspective
(American Meteorological Society, 1986)Techniques that have evolved during the hundred years that scientific severe thunderstorm forecasts have been prepared are reviewed. The early empirical rules developed by Finley, Showalter and Fulks, Fawbush, Miller and ... -
Objective and Subjective Precipitation Probability Forecasts: Some Methods for Improving Forecast Quality
(American Meteorological Society, 1986)This paper reports the results of an empirical investigation of some methods for improving the quality of precipitation probability forecasts. These methods include 1) techniques for adjusting subjective and objective ... -
An Experiment in Mesoscale Weather Forecasting in the Michigan Area
(American Meteorological Society, 1986)During an experiment in mesoscale weather forecasting in the Michigan area, consensus improved over NWS guidance in maximum/minimum temperature and probability of precipitation forecasts out to 24 hours. Forecasts were ... -
An Example of Subjective Interpretation of Network Profiler Data in Real-Time Forecasting
(American Meteorological Society, 1986)Wind profilers are capable of obtaining horizontal wind data from approximately 1?17 km at hourly intervals. A network of four profilers is being tested in Colorado. This note discusses a case in which profiler winds, taken ... -
Biases in MOS Forecasts of Maximum and Minimum Temperatures at Phoenix, Arizona
(American Meteorological Society, 1986)The biases of objective forecasts of maximum and minimum temperature for Phoenix are evaluated relative to the observed temperatures. The temperature forecasts were calculated from regression equations that had been derived ... -
Temperatures of Air Parcels Lifted from the Surface: Background, Application and Nomograms
(American Meteorological Society, 1986)When the temperature of a parcel lifted adiabatically from the surface to a given pressure level (SLT) is subtracted from the ambient temperature at that level, the result is the surface index (SLI) for that level. This ... -

VAS Sounding Images of Atmospheric Stability Parameters
(American Meteorological Society, 1986)Local forecasts often rely upon the extrapolation of trends seen in images of clouds from the GOES satellite. This work presents correspondingly high resolution images of atmospheric soundings calculated from the VAS ... -
The Austin, Texas, Flash Flood: An Examination from Two Perspectives—Forecasting and Research
(American Meteorological Society, 1986)During the evening of 24 May 1981, rainfall from a slow-moving, multicell thunderstorm exceeded 200 mm (8 in) in just 2 h over western sections of Austin, Texas. This intense precipitation, falling on previously saturated ... -
Conceptual Models of Precipitation Systems
(American Meteorological Society, 1986)Imagery from radars and satellites is one of the main ingredients of nowcasting. When used to provide very detailed forecasts of precipitation for a few hours ahead, the imagery needs to be interpreted carefully in terms ... -
Trends in the Quality of National Weather Service Forecasts
(American Meteorological Society, 1986)This paper describes the results of a study of trends in the quality of National Weather Service (NWS) forecasts from 1967 to 1985. Primary attention is focused on forecasts of precipitation probabilities, maximum temperatures, ... -
Objective and Subjective Precipitation Probability Forecasts: Statistical Analysis of Some Interrelationships
(American Meteorological Society, 1986)This paper addresses two specific questions related to the interrelationships between objective and subjective probability of precipitation (PoP) forecasts: Do the subjective forecasts contain information not included in ... -
Probability Forecasting in Sweden: Some Results of Experimental and Operational Programs at the Swedish Meteorological and Hydrological Institute
(American Meteorological Society, 1986)This paper describes new operational and experimental forecasting programs at the Swedish Meteorological and Hydrological Institute (SMHI) designed to provide users with more detailed and more useful weather forecasts. ... -
Supertyphoon Abby—An Example of Present Track Forecast Inadequacies
(American Meteorological Society, 1986)Supertyphoon Abby (1983), although not one of the most destructive on record, received a great deal of attention from the typhoon forecasters in Guam. For a large part of Abby's lifetime, nearly all objectively predicted ... -
Experiments in Temperature and Precipitation Forecasting for Illinois
(American Meteorological Society, 1986)Six years of daily temperature and precipitation forecasting are studied for Urbana, Illinois. Minimum temperature forecast skills, measured against a climatological control, are 57%, 48%, 34% and 20% for the respective ... -
