Orbital parameters (eccentricity, obliquity and precession) play important roles in determining glacial climate changes. We investigate the sensitivity of atmospheric GCM coupled to slab ocean and dynamical vegetation model (MIROC-LPJ; O’ishi and Abe-Ouchi, 2011) to changes in orbital parameters. We examine various orbital parameters to set eccentricity to 0, 0.01671, 0.03 and 0.0493, obliquity to 22.079, 23.439 and 24.480, and precession angles to every 30 degrees from 0 to 330 under different CO2 levels. We will discuss the dependence of seasonal and latitudinal temperature and precipitation on orbital parameters. We will also examine the role of dynamical vegetation change on temperature response to orbital parameters.
