In this paper we present some aspects of the fog classification and forecasting possibilities in autumn - winter in the Oltenia. To obtain significant results in terms of climatological, study of this phenomenon is necessary for a number of years, but this work is limited to the analysis of 2010, which, in winter there were 55 days with persistent fog Oltenia, representing the 21 cases. The analysis of synoptic situations in which the phenomenon was produced has been able to establish a number of baric structures that generate persistent fog and its type (inside the air masses and frontal), resulting in that warm anticyclones type determines fog advection-radiation and depressions occur in a front fog type, two physical processes are essential in producing this phenomenon: air cooling and evaporation. Finally we analyzed the case of advection-radiation fog type in the region of Oltenia, taking into account parameters and factors that proceeded kept phenomenon which led to its dissipation.

Systematic observations of weather and record of meteorological parameters in an interval of time (on the order of decades) allow the establishment of a climatic enviroment to which a certain meteorological event and it can be told if it is close or not. September, which is a hybrid between warm and cold season, may have features of both periods. In September 2008, the circulation of air masses over Oltenia led its division into two very different periods, producing thermal change abruptly. In this context, the synoptic analysis is relevant and can thus explain the evolution of temperature during this month.
