Title: A 2D climate energy balance model coupled with a 3D deep ocean model Authors: J. Ildefonso Diaz (Univ. Complutense de Madrid, Spain) Lourdes Tello (Univ. Politecnica de Madrid, Spain) Abstract: We study a three dimensional climate model which represents the coupling of the mean surface temperature with the ocean temperature. We prove the existence of a bounded weak solution by a fixed point argument. Published May 15, 2007. Math Subject Classifications: 35K55, 35K57, 58J32.
