One of the computationally intensive tasks in the numerical simulation of dynamic systems discretized on an unstructured grid over the sphere is to find a number of spherical minimum covering polygons of given locations, whose vertices are chosen from the grid points. Algorithms have been proposed attempting to perform this task efficiently. However, these algorithms only reduce the linear search time for each polygon vertex candidate by a constant factor, and their polygon search algorithms…

A Vertically Flow-Following Icosahedral Grid Model for Medium-Range and Seasonal Prediction. Part I: Model Description

AbstractA hydrostatic global weather prediction model based on an icosahedral horizontal grid and a hybrid terrain-following/isentropic vertical coordinate is described. The model is an extension to



Geometric Properties of the Icosahedral-Hexagonal Grid on the Two-Sphere

This paper presents an analytical analysis of several geometric properties of the icosahedral grids based on two basic constructions: recursive and nonrecursive construction and points out that these geometric properties can be improved with modified construction procedures.

Optimal Expected-Time Algorithms for Closest Point Problems

Algorithms for solving a number of closest-point problems in k- space, including nearest neighbor searching, finding all nearest neighbors, and computing planar minimum spanning trees can be implemented to solve practical problems very efficiently.

Near Neighbor Search in Large Metric Spaces

A data structure to solve the problem of finding approximate matches in a large database called a GNAT { Geometric Near-neighbor Access Tree} is introduced based on the philosophy that the data structure should act as a hierarchical geometrical model of the data as opposed to a simple decomposition of theData that does not use its intrinsic geometry.
