Title
It's not you, it's me: dipole dynamics in the atmosphere and ocean

Abstract
The Heton Model is a two-layer system, seeded with dipoles consisting of point geostrophic vortices. These vortices display a range of complex interactions and can effect a heat transport – hence the name Heton. Here we will show that this idealised framework can be applied to both the atmosphere and ocean. In the atmosphere, Heton dynamics can reproduce a number of features of the large-scale spatio-temporal variability of the meridional heat transport by transient motions. In the ocean, Hetons can be used to investigate the origin and dynamics of isolated sub-surface anticyclones which are often observed in the Arctic region.
