Method and apparatus for rating geographical areas using meteorological conditions

摘要

A method and apparatus for rating geographical areas based on the severity and/or frequency of different meteorological conditions. To determine the rating of a geographical area, raw data information from meteorological charts is gathered. The raw data scale for each meteorological condition is divided into ranges. The distribution of the geographical areas over the entire scale is determined. Individual rating factors are assigned to each of the ranges based on the distribution of the geographical areas throughout the scale. The individual rating factors are preferably selected such that the incremental change in the individual rating factors between ranges is preferably proportional to the incremental change in the number of geographical areas between the same ranges. All the individual rating factors for a single geographical area are used to calculate a cumulative rating factor for the geographical area. The cumulative rating factors of all the geographical areas are compared to provide a ranking of the geographical areas. The ranking relates to the risk potential in each geographical area based on the meteorological conditions. The resulting ranking of geographical areas is used to determine the insurability of a structure in a geographical area.
