Climate models

Cumulus clouds in trade-wind regions cover nearly 20 percent of our planet, producing a cooling effect. Until recently, it was assumed that global warming would reduce the surface covered by these clouds, amplifying the warming. However, a team around Dr. Raphaela Vogel from Universität Hamburg...

The new supercomputer Levante was inaugurated on September, 22, 2022 at DKRZ with high-ranking representatives from politics and science. The welcoming speeches were followed by two panel discussions on the challenges of climate research, which highlighted Hamburg's excellent reputation as a...

Even though our weather apps often promise otherwise, reliable weather forecasts can only be made for the next few days. That’s not good enough to predict hot summers. Conversely, even though good climate models can predict several decades into the future, they’re too imprecise for such...

What will the weather be like tomorrow, or the climate be like 20 years from now? Today, these questions are answered using complex computational models that spit out lists of numbers as long as your arm. These tremendous amounts of data often have to subsequently be transformed into graphics...

An ongoing research project at Universität Hamburg is intended to achieve a quantum leap in the quality of climate modeling. For the first time, all available measuring and observational data gathered worldwide over the past 50 years will be integrated. The German Research Foundation (DFG) has...

Klimaneutralität heißt das Ziel und die Debatten über den Weg dorthin sind in vollem Gange. Um es zu erreichen, sind tiefgreifende Veränderungen notwendig. Warum dies wichtig ist, zeigen Klimasimulationen. Ohne sie bleibt Klimapolitik blind. Wie Klimamodelle funktionieren und warum sie...

The Atlantic is generally considered to be Europe’s “weather kitchen” – bringing heat from the tropics to our coasts, it plays a critical role in predicting the weather. Nevertheless, it usually takes a backseat when it comes to forecasting: though atmospheric processes are closely monitored...

What will the climate be like two years from now – or ten? Though these medium-term predictions don’t have a particularly good track record, they are extremely important for policymakers and the agriculture and energy sectors, not to mention insurers. As an innovative new approach shows...

A team of researchers has mapped out how much waves are likely to change around the globe under climate change and found that if we can limit warming to 2 degrees, signals of wave climate change are likely to stay within the range of natural climate variability. The study was just published in...
