太阳入射辐射总量的计算与地球轨道参数对气候变化辐射项的影响

CALCULATING TOTAL AMOUNT OF INCOMING SOLAR RADIATION AND THE INFLUENCE OF THE EARTH’S ORBITAL PARAMETERS ON THE RADIATION TERM IN CLIMATIC CHANGE

中文摘要:

      本文给出的计算地球日射总量公式,在极圈内精度与Milankovitch公式一致,在极圈外仍具有极高的精度,而Milcnkovitch公式则不能应用。据此讨论了气候变化中地球轨道参数对辐射项的影响。结果表明,距今最近一次间冰期和冰期的日射分布特征与地质考古发现的新事实基本吻合,因而有可能在气候的未来变化中对辐射项进行预测。

英文摘要:

      In any latitude within the polar circle,the aceuracy of the formyla in the paper used for calculating the total amount of the astronomical insolation is similar to Milankovitch's formula,in the latiudes outside the polar circle the formula in the paper has a ligh aceuracy,but Milankovitch's formula is not fit for calculation because of its high erroe.Accordingly,the influence of the earth's orbital parameters on the radiation term in the climatic change is also discussed.The result is shown that the characteristics of the insolation distribution in the last glacial and interglacial periods over the Northern Hemisphere correspend to many of new facts in the geological evidence in the present time.Thus,it is possible to estimate the radiation conditions in future change of the climate.
