Abstract

The refractivity structure parameter C_n² characterizes the strength of refractive index fluctuations in the propagation path of electromagnetic waves and specifies the magnitude of the spatial power spectral density of turbulence-induced phase aberrations. In addition, the integrated value of C_n² along the propagation path determines the performance of the adaptive optical system. In this study, we explore the statistical relationship between the refractivity structure parameter and synoptic scale meteorological measurements. To this end, we have employed simultaneous measurements of the structure constant and meteorological data associated with fronts and jet streams at the synoptic scale. Using linear regression techniques, the degree of association between the meteorological data and radar-observed structure parameter values was computed. The parameters most strongly related to the structure constant are indicated; however, further research is needed to define the exact relationship between the refractivity structure constant and synoptic-scale meteorological data.
