The morphological and morphometric relief features, diversity of the active surfaces influencing air temperature distribution, especially the active influence of the Black Sea, position towards the Carpathian Orogen and large latitudinal extension of the studied aria, represent elements that compel towards a detailed study upon how air temperature is distributed and about the positive or negative thermal anomalies within the area under study. Therefore in order to determine thermal anomalies, 19 meteorological stations were used, stations running both within the area under study but also in its proximity. For the determination of air temperature anomalies, vertical thermal gradient for the whole Moldova region was computed and used, sequently the mean annual, of the January and July month air temperature was lowered according to sea level. Then, we used the horizontal thermal gradient range specific of the interval between 40°-50° North latitude of the continental area, to bring to a common latitude, for evidence the thermal anomalies. They are produced by local factors of the active surface, especially by the general routes of the general circulation of the atmosphere in this area, trails that are influenced by the major relief of the studied area and from greater distances and by the major baric activity centers. In the south of the studied area was revealed the role of wetlands and of the Black Sea. The results were mapped using, the residual kriging method.
