During the well-known "Little Ice Age" (LIA, ca. 1450–1850 C.E.), Europe experienced the coldest winters over the last ten thousand years. This interval was suggested to have been caused by major volcanic eruptions and periods of low solar activity. However, the detailed climate pattern in Europe remains unclear. By conducting high-precision...

Abstract The Little Ice Age (LIA; ca. 1450–1850 C.E.) is the best documented cold period of the past millennium, characterized by high-frequency volcanism, low solar activity, and high variability of Arctic sea-ice cover. Past studies of LIA Atlantic circulation changes have referenced the North Atlantic Oscillation (NAO), but recent studies...

Abstract The variability of the northern westerlies has been considered as one of the key elements for modern and past climate evolution. Their multiscale behavior and underlying control mechanisms, however, are incompletely understood, owing to the complex dynamics of Atlantic sea-level pressures. Here, we present a multi-annually resolved...
