Abstract: This paper summarizes the development of a convergent weighted-averaging interpolation scheme which can be used to obtain any desired amount of detail in the analysis of a set of randomly spaced data. The scheme is based ...

Abstract: Procedures for tuning a successive corrections objective analysis scheme, described in Part I, are applied to the array of North American rawinsonde stations. Tuning is investigated for three types of Barnes schemes (two-, ...

Abstract: Two recently published objective analysis schemes improve derivative estimates obtained from observed field variables. Achtemeier proposed a hybrid successive-correction scheme that uses a very low pass Gaussian weight ...

Abstract: An empirical approach is employed to investigate the accuracy of the Barnes successive corrections objective analysis scheme for discrete samples obtained from a simple sinusoidal function in a two-dimensional domain. Mean ...

Abstract: The accuracies of algorithms used to compute quasi-geostrophic diagnostic parameters such as Hoskins' Q-vector and its divergence are evaluated. Analytically-determined height values are invoked at grid points representing ...

Abstract: Data collected at the National Severe Storms Laboratory reveal the mesogamma-scale (2.5?25 km) features of two severe thunderstorms that struck Oklahoma City within 1 h of each other. This paper discusses the surface, upper ...

Abstract: National Severe Storms Laboratory radar film reveals twin hook echoes on the southeast flank of a tornadic thunderstorm (Storm G) that struck Oklahoma City on 30 April 1970. Only one mesocyclone is apparent in surface wind ...

Abstract: Newspaper accounts and damage tracks surveyed by National Severe Storms Laboratory staff reveal characteristics of three tornadoes that struck the Oklahoma City area shortly after midnight on 30 April 1970. Few details ...

Abstract: Using reported height data at mandatory pressure levels, a version of Hoskins' Q-vector analysis is computed for two layers, producing contoured patterns of vertical motion and other diagnostics at two levels. This analysis, ...
