Appendix 2: Conference Sessions
and Abstracts
In the following appendix, the Calls for Abstracts and the
abstracts of the oral and poster presentations of each session
of YOUMARES 8 are listed. The appendix chapters here are
ordered according to the corresponding proceedings chapters of the book, not according to the session numbers during the conference. While the appendix chapters 1 to 12
have a corresponding proceedings chapter, the chapters 13
to 15 do not.
1 Physical Processes in the Tropical
and Subtropical Oceans: Variability, Impacts,
and Connections to Other Components
of the Climate System

1.1 Call for Abstracts
The tropical-subtropical oceans are key regions of the global
climate system and affect livelihoods across the globe. We
invite research that is concerned with understanding and predicting variability, or dealing with its regional and global
impacts. Possible contributions include, but are not limited
to, observational and modeling studies about the El NiñoSouthern Oscillation, the Indian Ocean dipole, tropical
Atlantic variability, equatorial and eastern boundary upwelling systems, tropical monsoons, and tropical cyclones. While
we wish to focus the session on physical processes, we
strongly encourage researchers from other disciplines to submit studies that link biological, chemical, and other research
to the tropical oceans.

1.2.1 El Niño and Its Little Sister in the Tropical
Atlantic: Similarities, Differences and Interaction

*invited speaker, corresponding author: jluebbecke@geomar.de
In this talk, the main modes of climate variability in the
equatorial Pacific and Atlantic Ocean, namely the El Niño –
Southern Oscillation (ENSO) and the Atlantic Niño mode
will be compared to each other and their interaction will be
discussed. It will be shown that while both modes involve the
Bjerknes feedback, they exhibit differences with respect to
strength, timing and symmetry. As an example, the Atlantic
Niño mode is more strongly damped than ENSO, mainly due
to a weaker thermocline feedback that favors the growth of
SST anomalies in response to wind stress forcing. Also,
while ENSO is asymmetric for warm and cold events with
respect to amplitude, spatial patterns and temporal evolution,
in the equatorial Atlantic, cold events are effectively mirror
images of warm events. This behavior is rationalized by
means of the individual Bjerknes feedback components.

The response of the climate system to past and possible
future anthropogenic emissions has been one of the guiding
questions for several decades. The previously investigated
responses to anthropogenic climate change can be grouped
into changes of the mean state and changes of variability.
Both types of questions are difficult to answer, mainly
