Summer heat waves over Eastern China: dynamical processes and trend attribution

Autor: Nicolas Freychet, Simon Tett, Jun Wang, Gabriele Hegerl

Publikováno v: Environmental Research Letters, Vol 12, Iss 2, p 024015 (2017)

Recent trends in summer heat waves (HW) over Central-Eastern China and their atmospheric drivers are investigated using the ERA Interim re-analysis. A composite analysis shows that these events are preceded by an increase in 500 hPa geopotential heig

Linear precipitation response to increasingly strong volcanic eruptions and its emergence from internal variability

Autor: Claudia Timmreck, Dirk Olonscheck, Andrew Ballinger, Roberta D'Agostino, Shih-Wei Fang, Gabriele Hegerl, Andrew Schurer

Large explosive volcanic eruptions are a potential source of uncertainty in future climate projections as they cannot be predicted in advance, but eventually will occur, causing short-term climatic impacts on both local and global scale. Still, an op

The Global Energy and Water Cycle Exchanges (GEWEX) project was created more than 30 years ago within the framework of the World Climate Research Programme (WCRP). The aim of this initiative was to address major gaps in our understanding of Earth’s
