| Zusammenfassung |
| Recent trends (1979-2010) in summer heat waves (HW) over Central-Eastern China and their atmospheric drivers are investigated using the ERA Interim re-analysis. We focus on regional scale (105E-125E,30N-40N) and persistent events (more than 5 days), thus threatening for a large population.
A composite analysis is used to highlight the main dynamical processes associated with such events, and lag-composites show the evolution of the circulation before and after the heat waves. A particular attention is made on the possible feedbacks that can extend the length of the events.
The trend in the occurrence of such events is analysed and we conducted a simple attribution analysis to separate the changes in the background temperature and the possible changes in the atmospheric anomalies. |
