FILTERING RESPONSES OF SELECTED DISTANCE-DEPENDENT WEIGHT FUNCTIONS
Publisher: American Meteorological Society
Abstract: The filtering response of the Cressman weight functions and a truncated low-pass filter are presented as functions of influence radius.
VARIATIONAL RESOLUTION OF WIND COMPONENTS
Publisher: American Meteorological Society
Abstract: A variational formulation minimizing the square of velocity differences is used to determine boundary conditions for determination of velocity potential and stream function for the horizontal wind. The boundary velocity ...
Distance Distributions for Randomly Distributed Data
Publisher: American Meteorological Society
Abstract: Probability density distributions are derived and verified for the distance from an arbitrary point to stations randomly distributed in the plane. These distributions are essential to the analysis of the filtering properties ...
On Definable Scale Reduction by Simultaneous Observations
Publisher: American Meteorological Society
Abstract: A two-dimensional extension of the Sampling Theorem with the inclusion of derivative samples is presented. It is shown that simultaneous sampling of geopotential and horizontal wind components on a mesh with elements ?x, ...
Variational Initialization with the Balance Equation
Publisher: American Meteorological Society
Abstract: Diagnostic relations are derived whose satisfaction yields a unique adjustment of observational data such that the balance equation is satisfied. In this formulation both the observed geopotential and velocity fields are ...
RADAR CROSS-SECTIONS FOR WATER AND ICE SPHERES
Publisher: American Meteorological Society
Abstract: Radar cross-sections for water and ice spheres, evaluated by using the complete Mie theory and the method of Aden, are presented for wavelengths ranging from 0.43 to 16.23 cm. The validity of the Rayleigh approximation is ...
