 | The detailed development of two climatological data bases are presented. The first is a photographic sky cover data base from Columbia, Missouri consisting of the Regis College Research Center's interpretations of over 2800 photographs of the whole sky. It also contains point information taken from the photographs and concurrent NWS sky cover observational information. An analysis of the content of the data base, the derivation of sky cover frequency density ... |

|
| This program is an attempt at a large scale, multi-level general circulation model of the atmosphere. The original conception was to implement a very flexible program. The major programs are: INITE (Since a typical problem will require more storage than can be accomodated, this program parcels the data and codes information as to how it is partitioned.); GEX (A solution program to step the fields ahead in time.); and DISPLY ... |

|
| A program description for a large scale multi-level general circulation model of the atmosphere is presented. Several time integration scheme algorithms are discussed, and a linear stability analysis of finite difference approximation to a meteorological equation of motion is given. In addition, experiments involving the numerical solution of the non-divergent barotropic general circulation problem, using overlapping grid systems, are described and evaluated. Problems involving the numerical solution, via relaxation, of ... |

|
| Program environments suitable for the investigation of a large number of different grid systems and algorithms relevant for the solution of large scale meteorological circulation problems are presented. One of them employs a mixed grid system to solve the barotropic problem. Inconsistencies arising from linear interpolation between the grids followed by numerical differentiation are examined. Also, a spherical grid system with flexibility of definition on the globe is described and ... |
