The Evolution, or Seasonal and Interannual Variability, of the Diurnal Variation of Hydrometeorological Fields in the Southern Baltic SeaAbstract
We present the results of an analysis of field observations of the air temperature Ta, the dew point Td (relative humidity f), the sea-level atmospheric pressure P0, and the wind speed W. The data were obtained by a Mini- KRAMS-4 hydrometeorological facility installed within Russia’s exclusive economic zone in the southeastern Baltic Sea on the LUKOIL-KMN (D6) offshore ice-resistant fixed platform and at MARNET monitoring stations of the German Oceanographic Datacentre (BSH / DOD (M41)) in 2002—2016. Alongside meteorological elements, we studied the temperature Tw and the salinity S of the upper sea layer. Using our own time series model, we estimated the contributions of each mode to the total temporal variability. In the article, we examine the intrannual and interannual variability of the specific contribution of the daily component of hydrometeorological elements. We show that the time series structure (including the daily component) for the hydrometeorological elements in the southern Baltic Sea depends both on the location of the station and on the nature of each meteorological element.
