Description
Observations show that tropical Atlantic modes of variability are related to variability in the extratropics, such as the North Atlantic Oscillation. In the tropical Atlantic, low-frequency variability is characterized by anomalous cross equatorial meridional SST gradients and SST variations in the eastern cold tongue. We propose to study changes in the tropical Atlantic variability and its teleconnections due to CO2 rise in the atmosphere. We will use a new coupled ocean atmosphere model for this purpose (SPEEDO: the atmosphere model Speedy and the Micom ocean model). Unlike many other coupled models, this model shows relatively small biasses in the mean state and annual cycle of tropical Atlantic climate. It will be studied how the tropical Atlantic variability changes. We will focus on tropics-extratropics interaction. That is, it will be studied how the extratropical climate changes in response to changes in the tropical Atlantic through atmospheric bridges. Also, we will study whether these extratropical changes feed back on the tropical Atlantic through atmospheric and oceanic teleconnections. The SPEEDO model has a flexible set up which allows us to perform many targeted sensitivity studies to clarify the different feedbacks. Novel aspects of this proposal are the use of a new coupled climate model and the subject of changes of tropical Atlantic variability and its teleconnections due to CO2 rise.
