Time series of water temperature and salinity in the Azov Sea


1. Maps of the vertical distribution of climatic standards of water temperature and salinity


Vertical distributions of temperature and salinity, averaged for the period of 1891-2010 (climatic standards), are constructed for sections of the Sea of Azov. Their location by the vertical corresponds to standard horizons of 0, 5, and 10 m. Along the section they are located within 10 km of each other. Tables of vertical distribution of water salinity in August for the Don Delta – the Kerch Strait section are presented in Figure 1.

2. Maps of the vertical distribution of climatic anomalies of water temperature and salinity


To calculate the anomalies, inter-annual variability of average salinity data from the period of 1922-2010 was considered (Figure 2). Calculations following the mathematical model of Matishov et al., 2006 were made. The period of 1922-2010 was subdivided into 8 time intervals (1922-34, 1935-41, 1946-49, 1950-57, 1958-1970, 1971-81, 1982-2000, and 2001-2010), and temperature and salinity anomalies for the Sea of Azov were calculated within the ranges of these intervals. An example of the distribution of salinity is presented in Figure 1.
