Orbitally-Induced Variations in the Diurnal Cycle of Radiation

近几十年来，对地球轨道机制变化的气候影响的解释取得了进展，现在已经可以获得每月中期的卡路里日照总量。对这些日照变化的每一次改进都对地球轨道机制对地球气候的影响产生了新的见解。这一点很重要，因为对于当前的米兰科维奇气候变化轨道理论解释某些气候代理记录中发现的相互矛盾的信号的能力存在分歧。与这一理论相关的问题可以通过进一步改进轨道影响到白天的水平来评估和可能解决。这项研究通过计算机模拟模型定义了特定月中日晒总量的日(日)循环变化，从而继续了这一精炼过程。这些结果应该有助于解决古气候替代数据记录中过去的差异。通过将以前的米兰科维奇日照研究扩展到日尺度，该项目开辟了新的调查途径，并建议重新检查以前的气候变化研究。特别是，可以建立关于冰期终止、古季风事件发生和海平面上升波动的更准确的记录。

Interpretation of the climatic impact of variations in the earth's orbital mechanisms has progressed in recent decades to the point where individual mid-monthly caloric insolation totals are now available. Each refinement of these insolation variations has produced new insights into the influence of the earth's orbital mechanisms on the climate of the planet. This is important because disagreement exists about the ability of the current Milankovitch orbital theory of climatic change to explain conflicting signals found in certain climate proxy records. The problems associated with this theory can be evaluated and possibly resolved through further refinements in the orbital influence down to the diurnal level. This study continues that process of refinement by defining the variations in the diurnal (daily) cycle of specific mid-monthly insolation totals by means of a computer simulation model. The results should help to resolve past discrepancies in the paleoclimatic proxy data record. By expanding previous Milankovitch insolation studies to the diurnal scale, this project opens new avenues of investigation and suggests the need for re-examination of previous studies of climatic change. In particular, a more precise record can be established regarding the termination of glacial periods, the occurrence of paleomonsoon events, and the fluctuations in sea- level rise.
