We investigated the climate of the water-rich terrestrial planets systematically under various obliquities and semi-major axis, with a negative feedback mechanism of carbonate-silicate geochemical cycle. We use a one-dimensional energy balance climate model (1D-EBM) with a simple model of carbonate-silicate geochemical cycle in order to understand characteristic behaviors of the climate system of water-rich terrestrial planets. The major results obtained in this study are as follows; 1) "Permanent ice-cap mode" (the planet is partially covered with ice throughout the year) and "Seasonal ice-cap mode" (the planet is covered partially with ice seasonally) exist stably at low obliquities, but they cannot exist at high obliquities. This is because latitudinal gradient of annual mean insolation becomes smaller with an increase of obliquity. 2) "Ice-free mode" (there is no ice-cover throughout the year) can exist at the outer orbit and at high obliquities than that at low obliquities. This is because a decrease of meridional temperature gradient. 3) When carbonate-silicate geochemical cycle is taken into account, the range of semi-major axis for all the climate modes expand at any obliquities, compared with the cases without carbon cycle, indicating that the carbon cycle make the climate habitable for the planets with any obliquities and broad range of semi-major axis inside the habitable zone. |
