Numerical reanalysis through proportional differences
Glaes, Roger Burton
MetadataShow full item record
A new approach to numerical analysis is presented. In stead of providing conventional data one essentially pre scribes the desired pattern and the analysis is performed through proportional differences. If satellite or other data indicate a synoptic system in a numerical analysis should be reanalyzed, a three dimensional manual analysis is performed. Particular attention is given to the adjustment of the location and orientation of the synoptic pattern. No changes are per mitted on the borders of the finite area containing the synoptic system. Orientation axes for the patterns of the numerical and manual analyses are defined by sets of key points. Using the space difference between these orientation axes, the boundaries and the amount of development specified at the key points this scheme guarantees a reanalysis which smoothly blends with the original analysis and retains the new location and orientation of the synoptic system.
