Abstract:

A version of the correction objective map analysis scheme is developed and tested for the surface meteorological elements and the upper-air winds in the Caribbean region. In order to overcome the difficulty of getting reasonable analysis over the oceanic area devoid of data, a successive vertical differential analysis technique is employed for the upper wind analysis. Surface map analysis serves to obtain a reliable base for the upper wind analyses. Analysis of wind fields both at the surface and at upper levels is independent from pressure or height of constant-pressure surface-- observations. A statistical adjustment process is introduced to improve the surface pressure analysis with assistance from the independent wind analysis. For the upper wind analqses, vertically averaged winds over 50-or 100-mb pressure intervals are used. Besides a general description of the correction method employed, some technical problems in handling operational data are mentioned. In upper wind analysis, special caution is needed to insure a reasonable analysis over wide open areas without stations. It is found that the correction method tends to build a peculiar distortion of analyzed pattern in these areas. The results based on the experimental computations are illustrated with charts and discussed with some statistical results. Author
