扼要介绍了天文古气候学的创立和发展简史。太阳是地球大气运动的第一驱动力,地球气候的长期演变在很大程度上受到入射太阳辐射变化的影响。入射太阳辐射的变化主要和三个地球轨道参数有关,即地球绕太阳运行的椭圆轨道偏心率、地球自转轴倾角及岁差。太阳辐射的长期振荡主要集中在与这三个参数有关的频率上,这些频率通常被称为米兰柯维奇频率,数值模拟和地学记录都证实地质时间尺度的古气候的演化大多位于米兰柯维奇频率带上。这样,在一定程度上可以用太阳系天文轨道参数的变化来解释古气候演变。
Briefly introduced a brief history of the creation and development of astronomical climatology. The sun is the first driver of the Earth’s atmospheric movement and the long-term evolution of the Earth’s climate is greatly affected by changes in incident solar radiation. Changes in incident solar radiation are mainly related to three orbital orbital parameters, that is, the elliptical orbital eccentricity of the earth around the sun, the inclination of the Earth’s rotation axis, and the precession. The long-term oscillations of solar radiation mainly focus on the frequencies associated with these three parameters, which are often referred to as Milanovic frequencies. Numerical simulations and geoscientific records confirm that the evolution of palaeoclimate at the geologic time scale is mostly located in the Milanovic frequency band . In this way, to some extent, the evolution of palaeoclimate can be explained by the changes in solar system astronomy orbit parameters.
