Rainfall Variability and Trend Analysis of Multiannual Rainfall in Romanian Plain
Abstract The IPCC climate models predict, for the Central Europe, are for climate changes, being seen variability of temperature, with a growing trend of 1-2,5° C (with 1° C for alpine zone – Carpathians and 2-2,5° C for plains). Current observations in the Romanian plain are not consistent, with an...
