The department investigates climate and Earth-system variability on all timescales from seasonal to millennial. The main research tools are coupled ocean-atmosphere and Earth-system models, but observations, statistical analysis, and data assimilation are also employed to improve the understanding of past, current, and future climate variability. A particular focus lies on the role of the ocean in climate variability and change. The department is the home of the ocean component of…

Three fellowships for George Datseris

Dr. George Datseris, a scientist previously working in the department “The Atmosphere in the Earth System” at the Max Planck Institute for Meteorology, was recently granted a Marie Skłodowska-Curie Actions Postdoctoral Fellowship. This honor follows on two other successful postdoctoral fellowship applications, one from the Royal Society International Newton Fellowship, and the second from the German Research Foundation (DFG) Walter Benjamin postdoctoral fellowship, which cap a very productive…

Fairweather cumulus are here to stay after all!

“Eureka!” That is what the Greek scholar Archimedes is said to have exclaimed in delight upon discovering buoyancy. More than 2,000 years later, the similarly named meteorological field campaign EUREC4A has studied some of the implications of buoyancy, and in so doing provided some welcome news: cumuli in the subtropics diminish less with warming than the most sensitive models predict. Climate change need not necessarily be amplified by enhanced absorption of solar radiation.

Research ships

Around 70 % of the Earth are covered by oceans. The significance of the interaction between ocean and atmosphere cannot be overestimated. Yet, the vast majority of measuring stations are located on land. Satellite observations can compensate to some extent for the lack of measurements over the oceans. However, it is often difficult to obtain high-resolution data close to the surface which is precisely the region where exchange between ocean and atmosphere takes place and which is therefore…

Observations

Observations are data records collected with the help of scientific measuring instruments. There are, for example, countless weather stations around the world that measure temperature on land, in the air and in the sea as well as satellites, ships and aircraft that also take measurements of various variables. Observations are enjoying a renaissance at the Max Planck Institute for Meteorology. There are two main reasons for this. One is that the main tools we use to study the climate…

The effect of climate perturbations on the timing of Heinrich events

Throughout the last glacial period (ca. 65,000-15,000 years before present) periodic ice discharge events from the North American ice sheet, known as Heinrich events, shaped the climate evolution of the northern Hemisphere. However, the driving mechanisms behind these events remain elusive to this day. In a new study, Schannwell et al. investigate the sensitivity of Heinrich events to different climate perturbations. They find that changes in snowfall and surface temperature can pace the timing…

AMOC sensitivity to icebergs

AMOC sensitivity to iceberg forcings The last glacial cycle was characterized by a number of abrupt cooling events in the North Atlantic known as Heinrich events. Heinrich events are associated with massive ice sheet surges from the former Laurentide ice sheet and subsequent predominantly eastward transport of icebergs across the North Atlantic. Paleo records also indicate that ice discharge events coincided with a weakening of the Atlantic Meridional Overturning Circulation (AMOC). Typically,…

Self-sustained AMOC oscillations

AMOC response to different forcing and self-sustained AMOC oscillations State-of-the-art coupled climate models produce very different states of the Atlantic Meridional Overturning Circulation (AMOC) in simulations of the Last Glacial Maximum (LGM). Many of them fail to capture the shoaling of the North Atlantic Deep Water (NADW) cell, as indicated by paleo records. The mechanisms that control the shoaling are not yet well understood. Changes in the AMOC have also been linked to past abrupt…

Fully coupled climate-ice sheet simulations

Fully coupled climate-ice sheet simulations of the last deglaciation The climate system has undergone dramatic changes during the last deglaciation from 21,000 years before present to present day. For example, the Laurentide ice sheet over North America and the Fennoscandian ice sheet over Northern Europe have completely disappeared. This collapse of the ice sheets was accompanied by a global sea-level rise of ~120 m. The individual climate components and their responses to changing conditions…
