Winter precipitation trends for two selected European regions over the last 500 years and their possible dynamical background
Summary: We analyse winter (DJF) precipitation over the last 500 years on trends using a spatially and temporally highly resolved gridded multi-proxy reconstruction over European land areas. The trends are detected applying trend matrices, and the significance is assessed with the Mann-Kendall-trend...
