Abstract The Twentieth Century Reanalysis (20CR) project is an international effort to
produce a comprehensive global atmospheric circulation dataset spanning the twentieth …

The most pronounced warming in the historical global climate record prior to the recent
warming occurred over the first half of the 20th century and is known as the Early Twentieth …

Because of global warming, high‐latitude ecosystems are expected to experience increases
in temperature and drought events. Wood formation will have to adjust to these new climatic …

Climatic variations at decadal scales such as phases of accelerated warming or weak
monsoons have profound effects on society and economy. Studying these variations …

Data assimilation is a promising approach to obtain climate reconstructions that are both
consistent with observations of the past and with our understanding of the physics of the …

Over the last 300 years, countless climatic variations at different places and times have been
witnessed, some affecting millions of people and changing the course of history, some going …

This study spanning the period 1851–2015 explores the spatial and temporal characteristics
of dry and wet periods in Europe as well as their variability and changes. It is based on up to …

To better understand variability in weather and climate, it is vital to address past atmospheric
circulation. This need requires meteorological information not just from the surface but also …

A simple closed contour object identification scheme has been applied to the zonal mean
monthly mean zonal wind fields from nine global reanalysis data sets for 31 years of the …

The statistical significance of Global Atmospheric Oscillation (GAO), whose main element is
the well-known El Niño–Southern Oscillation in the equatorial Pacific, was assessed from …
