Posibilități de estimare a variabilității climatice prin intermediul unor noi indici elaborați la nivel regional

Abstract

The essential climatic variability in the structure of thermal extremes, the minimum and maximum values, the temperatures in the coldest and warmest month of the year and their thermal amplitudes, respectively, conditioned the elaboration of the Thermal Variability Index (IVT) and the Singularity Thermal Variability Index (IVST). Rainfall excesses and their consequences have contributed to the elaborated of the Rainfall Excess Index (IP) and the Rainfall Hazard Index (PPI). In order to highlight the impact (negative or favorable) on the agricultural sector, the Index of Dry Periods (Izu) and the Nedealcov-Rapcea Coefficient of climate pretability for grape quality (CNR) were elaborated. The negative impact that the increased hot days have on the state of the forest ecosystem determined the elaboration of the Forest Stress Aridity Index. We believe that, although a multitude of climate indices are known to contribute to complex climate estimates, the development of regional indices (some of which are applicable abroad) highlights the regional peculiarities of the current climate and the impact of climate variability and change for different daily activities.
