Patterns of low-frequency climate variability: a model-paleodata comparison
Abstract niet beschikbaar Patterns of temperature variability on interdecadal and longer timescales are derived from empirical and simulated data for the region centered around the North Atlantic ocean. The empirical dataset consists of long early-instrumental records and high-quality proxy data. Th...
