Variation of the radiation
field in the northern area of Azov see
Abstract
The statistical methods were
used for the fluctuations analysis of a radiating field in the northern part of
the Azov sea during 1987–2002. The purpose of the Spectral (Fourier) analysis
was to decompose a complex time series with cyclical components into a few
underlying sinusoidal functions of the particular wavelengths. It was
established, that the gamma– background changes from time to time under the
complex law including, monotonous drift of a base line, white noise, processes
with intermittency, such as Flikker-noise, numerous seasonal and cyclic
fluctuations. Model of autoregressive and moving average was offered, its
parameters were designed and was carried out forecasting.
