The Assessment of the Agro-climatic Parameters and Coefficients Employed in the Drought Evaluation

The theme of the article is of theoretic and didactic nature, providing the systematization of agro-climatic parameters and coefficients, necessary for the explanation and evaluation of the drought phenomenon, within a precise geographic region. Through interactions and consequences on a social level, economical and political, the drought phenomenon represents an environmental problem, which implies analyses on a global scale, regional, national and local, with the purpose of establishing some specific measures of prevention and control. Therefore, the correct employment of climatic data (elements, parameters and coefficients) represents an effective way of approaching the organization, management, analysis and contrasting of elaborated studies which have as a subject the characterization and detection of the aridity and/or drought phenomenon. The article is based on professional literature, acting as an inventory of the main agro-climatic parameters and coefficients utilised in the assessment of the drought phenomenon, on a national and international scale.
