アブストラクト	Idealized set-ups offer a great laboratory to explore the most fundamental aspects of climate dynamics. In this lecture, I will describe a series of idealized GFD experiments with a numerical model of the coupled ocean-atmosphere-sea ice system. To focus on the coupling of the two fluids in its most elemental form, we avoid the complication arising from a realistic representation of geography/land-sea distributions. We use Aquaplanet set-ups where narrow continents are absent are reduced to narrow land barriers. Moving land barriers allows, for example, to turn on/off various components of the ocean circulation (gyre, circumpolar current, inter-hemispheric meridional overturning...). I will discuss some of the key findings of these experiments in an Earth-like configurations, as well as applications in an exoplanet context.
