interpretation
1

basis: The oldest part of the reconstruction is characterized by a prolonged period of relatively wet conditions (1360a€“1450), followed by a period of drier conditions until 1600. Another wet period until 1760 follows, with a short increase to relatively drier conditions around 1720. The most marked trend in the reconstruction is the shift to dry conditions from 1760 to 1850. The late 20th century is characterized by increasingly dry summers, but these SPEI values are not unprecedented in the record.
