Climate change: Linear and nonlinear signatures

  title={Climate change: Linear and nonlinear signatures},
  author={Klaus Hasselmann},
It seems likely that the warming of the Earth's atmosphere is caused by anthropogenic emissions of greenhouse gases, and that the warming trend will continue long into the future. What have been, and will be, the consequences for the occurrence of extreme events such as storms, floods and droughts? There are no straightforward answers, but climate models employing nonlinear analysis may be a way forward.

Is Climate Predictable
Two forms of climate prediction are considered: the forecast of natural climate fluctuations such as El Nino, and the determination of the effect of human activities on the future climate. AlthoughExpand

Recurrent climate winter regimes are examined from statistically reconstructed and modelled 500 hPa geopotential height fields over the North Atlantic/European sector for the period 1659–1990. WeExpand
Reduction of deterministic coupled atmosphere–ocean models to stochastic ocean models: a numerical case study of the Lorenz–Maas system
Our starting point is the Lorenz–Maas coupled atmosphere–ocean model which was proposed by van der Schrier and van Veen and couples the ocean model by Maas with the Lorenz-84 model of the atmosphere.Expand


Signature of recent climate change in frequencies of natural atmospheric circulation regimes
A crucial question in the global-warming debate concerns the extent to which recent climate change is caused by anthropogenic forcing or is a manifestation of natural climate variability. It isExpand
