Abstract



The paper explores the link between water temperature of the subtropical part of the Atlantic Ocean (the belt of 25 to 40° N), atmospheric pressure and air temperature in Belgrade and Serbia. The main point of the research is to examine the linkage between the Azores air pressure maximum with the changes of water temperature in the subtropical belt of the Atlantic (given in the net 5x5°). Using the hierarchical cluster analyses, 10 clusters of water temperature of the subtropical part of the Atlantic Ocean were selected. Their linkage between the position and the intensity of the Azores maximum was examined by multiple-linear regression. It was established which of the clusters influenced most the geographical latitude, geographical longitude and the intensity of the Azores maximum, as well as which of the grid cells represented the most significant predictors within each of the clusters. Examining the relation between the position and the intensity of the Azores maximum with the air temperature in Belgrade, i.e. Serbia, it was established that the linkage with the geographical latitude of this action centre was the most significant.
