【摘要】 在文[1]的基础上,假定下垫面全为海洋,大气和海洋之间存在热量交换,而海洋中只考虑热量的湍流输送过程。在这种情况下,本文指出,考虑或不考虑海洋湍流输送对全球平均纬向分布以及冰界纬度与太阳常数的依赖关系影响不大。文中还进一步分析了各种参数变化对冰界与太阳辐射依赖的敏感性,并给出了一个简单的物理解释。分析表明,当各种参数在允许范围内变动时,可以得到与实况相近的现代气候。这时,欲要出现冰河期,太阳常数应减小14—19％,不会像一维模式那样只要减小2％。说明现代气候对太阳常数的变化是处于相当稳定的状态。这是二维模式中相互制约的物理过程在起作用的结果。更多还原

【Abstract】 On the basis of paper (1),an atmso-ocean coupling model which takes account of the turbulent transport process only in the ocean and of the exchange of heat between atmosphere and ocean was developed. The distribution of temperature of sea surface was recalculated. The sensibility of climate evolution to the change of solar radiation was examined. It was concluded that the results with or without considering ocean are identical.更多还原
