Investigating a Possible New Source of Modeling Error for Estimates of Continental Surface Temperatures in Paleoclimate Studies

9627795斯隆这项研究的目的是从模型结果与代用数据解释始新世大陆温度之间差异的可能模型来源的角度，调查大陆(即与大片陆块有关的温度)的问题。大陆内部气候特征问题一直是古气候学的主要问题和最活跃的争论之一。在模型计算中加入正确的纬向温度廓线以及年周期，可能会导致冬季冻结线位移较大，以及其他温度参数的相关变化。这项工作将侧重于(I)模型预测的全年冻结线的位置和位置(包括对应于各种生物容忍限度的+2、0、-2和-5摄氏度的等温线)，(Ii)大陆温度的年变化幅度，(Iii)大陆内陆地区的夏季最高温度值。

9627795 Sloan The purpose of this study is to investigate the issue of continentality (i.e., temperatures associated with large land masses), from the perspective of possible model sources for discrepancies between model results and proxy data interpretations of Eocene continental temperatures. The issue of continental interior climate characteristics persists as one of the major questions and most active debates of paleoclimatology. Inclusion of the correct zonal temperature profile, along with the annual cycle in model calculations, may result in large winter freeze line displacements, and associated changes in other temperature parameters. This work will focus on (i) the position and locations of the model-predicted freeze line throughout the year (including isotherms for +2, 0, -2 and -5 degrees C, corresponding to various biologic tolerance limits), (ii) the annual amplitude of temperature change over the continents, (iii) the summer maximum temperature values in continental interior regions.
