New theory for radiatively driven shallow circulations

In a new study recently accepted in the Journal of Atmospheric Science, Ann Kristin Naumann, Bjorn Stevens, Cathy Hohenegger and Juan Pedro Mellado from the Max Planck Institute for Meteorology (MPI-M) show that shallow circulations driven by radiative differences can be as strong as those driven by surface temperature differences.

The scientists...

New study: Why European winters were so cold during the Little Ice Age

Our common conception of the Little Ice Age (LIA), the relatively cold climate period that climaxed in the 16th-18th centuries, is strongly influenced by painters like Brueghel the Elder or Avercamp and their famous genre scenes of winter hardships and pleasures in icy landscapes. These idealized representations of daily life are nonetheless...

Why are shallow cumuli bigger and stronger over land than over ocean?

In a new study appearing in the Journal of Atmospheric Sciences, Dr. Mirjana Sakradzija and Dr. Cathy Hohenegger, both scientists in the group "Clouds and Convenction" at Max Planck Institute for Meteorology (MP-M) in the department "The Atmosphere in the Earth System", identified key processes influencing the size of clouds. The questions why...

The Max Planck Institute for Meteorology

The Max Planck Institute for Meteorology (MPI-M) is an internationally renowned institute for climate research. Its mission is to understand Earth's changing climate.

The MPI-M comprises three departments and, together with the University of Hamburg, an international PhD programme:

The Atmosphere in the Earth System

The Land in the Earth System
The Ocean in the Earth System
PhD Programme IMPRS-ESM

In addition the institute hosts independent research groups focused on the following topics:
