An Iterative Method for Altering the Kinematic Properties of Wind Fields
(American Meteorological Society, 1967)Grid-point values of eastward and northward wind components imply that specific fields of divergence, vorticity and deformation exist. For certain purposes, one may wish to change the winds slightly to make them non-divergent, ... -
A Comparison of FPS-16 and GMD-1 Measurements and Methods for Processing Wind Data
(American Meteorological Society, 1967)A machine method for computing winds from radiosonde and GMD-1 rawin tracking data is developed and the resulting winds are compared to those computed from precision FPS-16 radar tracking data. A direct comparison is ... -
On Optimum Methods for Obtaining Wind Data from Balloon Sensors
(American Meteorological Society, 1967)A sinusoidal wind field is integrated to give the position of a sensor traveling with a constant vertical velocity. A linear least-squares smoothing technique is employed to calculate the velocity and acceleration of the ... -
A Climatological Study of the Atmospheric Circulation in the Southern Hemisphere during the IGY, Part II
(American Meteorological Society, 1967)The seasonal variations during the IGY of sea-level pressures, 500-mb heights, and 1000-500 mb thickness in the Southern Hemisphere are examined to see if they conform to patterns which are deemed intrinsic to the hemisphere. ... -
Empirical Eigenvectors of Sea-Level Pressure, Surface Temperature and Precipitation Complexes over North America
(American Meteorological Society, 1967)The combined representation of fields of three climatic variables with empirical orthogonal functions, herein referred to as eigenvectors, is discussed. The eigenvectors are derived from measurements of monthly mean sea-level ... -
A Synoptic Climatology of Winter Precipitation from 700-mb Lows for Intermountain Areas of the West
(American Meteorological Society, 1967)A synoptic climatology of precipitation resulting from upper closed lows is developed for the intermountain area of the West for the winter months of December, January and February. Precipitation amounts at about 280 ... -
Experiments in Objective Frontal Contour Analysis
(American Meteorological Society, 1967)Following the methods of Clarke and Renard, experiments were made in the objective analysis of upper level fronts, using wet-bulb potential temperature, layer thickness and geostrophic horizontal wind shear as parameters. ... -
Goodness of Fit of a Markov Chain Model for Sequences of Wet and Dry Days
(American Meteorological Society, 1967)Evidence from locations in the north central region of the United States indicates that a rainy spell is more likely to terminate after at least two wet days than after one wet day during early spring. However, the departure ... -
Use of Probability Forecasts to Maximize Various Skill Scores
(American Meteorological Society, 1967)Whereas categorical forecasts designate a specific category of weather as the predicted future condition, probability forecasts express the uncertainty attending a forecast by giving estimates of the probability of occurrence ... -
The Verification of Probability Forecasts
(American Meteorological Society, 1967)Brier's scoring procedure for the evaluation of probability statements is analyzed to show two important aspects of the forecasting process. The first is a sorting process in which the forecaster assigns each prediction ... -
Verification of Probabilistic Predictions: A Brief Review
(American Meteorological Society, 1967)The evaluation process is considered in some detail with particular reference to probabilistic predictions. The process consists of several ordered steps at each of which elements (of the process) are identified. Consideration ... -
Verification to Determine and Measure Forecasting Skill
(American Meteorological Society, 1967)Three distinct purposes for the verification and scoring of forecasts have been generally recognized: determination of the accuracy of the forecasts, their operational value, and, lastly, the skill of the forecaster. ... -

An Airborne Precipitation Collector
(American Meteorological Society, 1967)A high-volume airborne precipitation collector is described. The device, installed in the nose of a twin-engine aircraft, has a 30-cm diameter intake that extends ahead of the aircraft nose. Both air and rain enter the ...
