Probabilities of Pressure Heights Forecast by Graphical and Numerical Methods
Publisher: American Meteorological Society
Abstract: A statistical theory developed previously is applied to two prediction techniques: graphical integration of Estoque's baroclinic model and numerical integration of a barotropic model. In both instances, synoptic observations ...
Computed Probabilities of 500-mb Heights Predicted by Graphical Integrations of a Barotropic Model
Publisher: American Meteorological Society
Abstract: A statistical theory developed previously is applied to graphical predictions of the 500-mb surface, using a barotropic model. Synoptic observations are regarded as samplings of the initial state. Probabilities of initial ...
On the Theoretical Predictability of Extrapolation Methods
Publisher: American Meteorological Society
Abstract: By use of a statistical theory developed previously, five extrapolation formulas are generalized to take into account uncertainties of initial states, due to lack of information between observing stations. This furnishes ...
ON THE THEORY OF CROSS-VALLEY WINDS ARISING FROM DIFFERENTIAL HEATING OF THE SLOPES
Publisher: American Meteorological Society
Abstract: By means of equations of horizontal motion and astronomical considerations, expressions are derived for a cross-valley wind caused by differential solar heating on opposite slopes. Friction, inertia, the Coriolis force, ...
EFFECTS OF VARIOUS FACTORS ON VALLEY WINDS
Publisher: American Meteorological Society
Abstract: A relation is derived for the periodic valley wind as a function of time and elevation, in terms of the diurnal temperature variation, slope of the valley floor, eddy viscosity, the Coriolis force, and a pressure force ...
Statistical-Dynamical Predictions
Publisher: American Meteorological Society
Abstract: By analogy with Gibbs' statistical mechanics, a statistical-dynamical theory is described which can be applied to the problem of atmospheric predictions from synoptic charts. The m variables and constants whose measurement ...
Probability Predictions of Geostrophic Winds
Publisher: American Meteorological Society
Abstract: A network sampling theory developed previously is used to obtain limiting probabilities of geostrophic wind components predicted at 500 mb in several synoptic cases. Analogous probabilities are calculated for the kinetic ...
A THEORY OF ANNUAL TEMPERATURE VARIATIONS
Publisher: American Meteorological Society
Abstract: Solutions for the differential equation of heat flow as applied to the atmosphere and to the ground are related by surface boundary conditions. One condition represents a vertical energy balance involving annual variations ...
