If the precipitation data of the last twelve months (from March 1, 2021 to February 28, 2022) are analyzed, we can speak of “a situation of meteorological drought in the whole of Spain”as well as in most of the representative basins of Aemet (similar, but not the same, to the hydrographic basins), except in those of the Júcar and the Segura.
