The number of bioclimatic or agro-climatic classifications and regionalization approaches is quite high. Some of them are of general use, while others are related to specific regions. As factors that cause micro- and mesoclimate formation serve: proximity to large water bodies, elevation and slope changes etc. Temperature and precipitation are determined by elevation, latitude and orographic barriers that lead to the appearance of characteristic macro and microclimatic patterns. The given regionalization is bioclimatic in nature, identifying areas with similar climatic conditions that influence the potential of vegetation and the distribution of ecosystems.
