THE PLUVIOMETRICAL EXCEEDING AND DEFICIENT PERIODS IN THE SOMEŞAN PLATEAU
V. SOROCOVSCHI, CS.HORVATH
ABSTRACT.- The pluviometrical exceeding and deficient periods in the Someşan Plateau. In the following paper is analyzed the short time periods (season and month) with pluviometrical exceeding and scarcity in a region with predominant western climatic influences, but also with nuances determined by its geographic position and by its morphometrical conditions in the area and around it. For this there were used data for a period of 40 years (1970-2009) from 2 meteorological stations and 10 pluviometrical posts. From the large range of methods to evaluate scarcity periods, we used the method of WASP Index (Weighted Anomaly Standardized Precipitation). These exceeding and deficient periods were determined for periods of three months (seasons) and one month (February and June), because they better highlight the torrential rainfalls characteristics. Also, they allow better exposure of risk situations determined by exceeding and scarcity pluviometrical periods.
