CliSAP successfully finished in 2018. Climate research continues in the Cluster of Excellence "CLICCS".

Visiting CliSAP: Amos Winter


Amos Winter, a paleoclimatologist/ paleoceanographer from Puerto Rico, has been visiting CliSAP as a guest researcher for a seven-week period now since early July. During this time he supports the work of Uwe Mikolajewicz in the research area “Arctic and Permafrost Regions”. He is a professor in the Department of Marine Sciences at the University of Puerto Rio where he has been for nearly 30 years. Originally hailing from Zurich, Switzerland, Winter will contribute his broad experience to the Cluster. During his stay, his goal is to support climate models by adding observation data from the tropics.

Guest researcher Amos Winter

CliSAP: How long have you been interested in climate research? And why does it fascinate you?

Winter: I have been working in the field for over 20 years now. I feel climate variability can be compared to the physiology of the human body, in that there are many interconnections.  Therefore, disruptions in one part of the system can have a rippling effect throughout the system. That’s what is so fascinating about the climate system.

CliSAP: What made you choose to visit the Cluster of Excellence CliSAP?

Winter: CliSAP offers an ideal community of researchers and expertise to work with and contribute to, that I hope I can do in the paleoclimate field.

CliSAP: Not everybody at the Cluster of Excellence is familiar with paleoclimatology. Could you explain in layman’s terms what you want to work on while you are at CliSAP?

Winter: Climate models have developed rapidly over the last few years, but still need to be refined with the help of observations. I hope that the observations that I bring from the paleo proxy community can ground the models in concrete facts to help make them more accurate.

CliSAP: Who are you working with at CliSAP, and where?

Winter: I am working with Uwe Mikolajewicz at the MPI.  I usually work in room 216 in the ZMAW building

CliSAP: How will CliSAP benefit from your experience in the field of mathematical models? And what will you take with you when you go back home?

Winter: I work on many different types of (mostly) carbonate proxies (corals, sclerosponges and speleothems) that provide high-resolution information on past environmental conditions primarily from the Holocene (the last 10,000 years). These will improve our understanding of the past boundary conditions that are so critical to model development. And I will take home a much better appreciation of these models.

CliSAP: What is the goal of your trip?

Winter: A new collaboration, improved models, a better understanding of Earth system dynamics, and collaborative proposals.

CliSAP: Thank you for your time, and have a good stay in Hamburg!
