Abstract. An Analysis of the Hydrometeorological Hazards and Their Impact on the Environment in Târgovişte Plain.  Through their impact on the environment and on the socio-economic activities hydrometeorological hazards trigger natural and ecological imbalances, having a negative influence on the geosystems evolution. The analysis of the main hydrometeorological elements allows for a characterization of the geographic area of Târgovişte Plain based on the data recorded at the meteorological stations from Târgovişte and Titu during the interval 1961-2007. In the present analysis, we took into account the thermo hazards (heat waves and cold waves), pluviometric hazards (periods of too much or too little rain) and their impact on the environment of Târgovişte Plain.

The most intense cold/heat occurrences are considered the moments when the extreme monthly temperatures go over certain threshold values: the absolute maximum monthly temperature ≥35°C or the absolute minimum monthly temperature ≤-20°C.

In point of the study of the periods with too much/too little rain, we calculated and interpreted the annual, seasonal and monthly values of the Standardized Precipitation Anomaly (ASP).

Key words: Târgovişte plain, hydrometeorological hazards, standardized precipitation anomaly.
