Research Abstract |
In this study, parameter experiments on structures of moist atmospheres on synchronously rotating planets are performed, and model infrastructure needed for realistic simulations are developed. Parameter experiment with various planetary rotation rate show existence of oscillating north-south asymmetric states and occurence of multiple equilibrium. Parameter experiment with various solar constant show that the value of solar constant at which the runaway greenhouse states occur changes about 100W/m^2 according to the value of planetary rotation rate. Moreover, radiation scheme for hydrogen atmospheres and a data input/output library are developed.
