Computing for Climate (part 2): How Modern Climate Models Work
Zukunftsblog

In our previous blog we drew an arc in time from the first theoretical weather computation to present-day climate calculations on massively-parallel computer systems. This follow-up post deals with the climate models and addresses the basic question: How can we simulate the evolving condition of the atmosphere?

The desire to foresee the weather and climate probably goes back to early mankind. Whereas experience in reading the signs of weather changes has long helped for short-term predictions of a few hours, it is only for a few decades that we have been able to forecast weather over several days – and simulate the future climate.
