How cold is it under thunderstorms? Measuring cold pools in Hamburg

Scientists at the Universität Hamburg and the Max Planck Institute for Meteorology (MPI-M) are measuring a weather phenomenon that we all know well, especially these days: thunderstorms. The weather is warm and nice, and suddenly a thunderstorm pops in the sky and produces extreme downpours for a brief instant. During such events, the air...

Multiple drivers of the North Atlantic warming hole

A new study in Nature Climate Change, led by Paul Keil of the Max Planck Institute for Meteorology, uses climate model simulations to identify additional drivers of the so-called North Atlantic warming hole.

Internal variability dominates short-term surface temperature trends

A new study by Dr Nicola Maher, Dr Flavio Lehner and Prof Jochem Marotzke demonstrates that in the coming 15 years any individual point on the globe in climate models could observe a cooling (or lack of warming) trend even under increasing greenhouse gas emissions.

Extreme summertime heat in a warmer world: where does it come from, and can we avoid it?

In two new publications, scientists at the Max Planck Institute for Meteorology (MPI-M) studied the current and future development of extreme heat events. They identified major risk hotspots for different forms of extreme heat under different global warming levels, and disentangled the drivers of increasingly intense European heat extremes.

Multi-year forecasts can predict natural atmospheric CO2 variations

In a new study Aaron Spring and Dr. Tatiana Ilyina, researchers at the Max Planck Institute for Meteorology (MPI-M), were able to show that the atmospheric CO2 concentration is predictable for three years in advance [Fig. 1 c] and that the land carbon cycle limits longer predictability.
