STATISTICAL CHARACTERISTICS OF PROGNOSTIC METEOROLOGICAL FIELDS AND THEIR USE IN OBJECTIVE ANALYSIS

O. A. Aldukhov, A. N. Bagrov, and V. A. Gordin

The estimates are made for three dimensional fields of biases and variances of deviations of prognostic fields from upper air sounding data. A procedure of variational adjustment of geopotential and temperature profiles in hydrostatic sense is developed. The corresponding corrections introduced to the first guess fields in objective analysis result in an improved objective analysis of geopotential.
