The seasonal cycle in a coupled ocean-atmosphere model

Abstract

These experiments include changing the longitude of perihelion, increasing the heat capacity of land, and changing the length of the solar year. The results demonstrate that the date of perihelion and land heating do not, by themselves, control the annual cycle. A experiment addresses the factors determining the season in which upwelling occurs. In this experiment the sun is maintained perpetually over the equator (simulating March or September conditions). In this case the atmosphere and ocean move toward September conditions, with a southern Hemisphere cold tongue and convection north of the equator. -from Authors
