Theoretical Paleoclimate Research at Texas A & M University

在气候动力学领域，一个长期争论的科学问题是极地冰盖的不稳定性。本研究的重点是利用能量平衡模型（EBM）和动态冰盖模型研究季节性雪线的稳定性。EBM将用于研究地理变化与季节变化雪线的相互作用。这个问题很重要，因为它可能与冰期开始时冰原的形成有关。此外，将EBM与动态冰盖进行比较，以模拟导致冰盖突然生长衰减的条件，从而再现可与地质时间尺度上观测到的气候进行比较的长期模式气候行为。

A long debated scientific problem in the area of climate dynamics is the instability of polar ice caps. This work focuses on investigating the stability of seasonal snow lines using an energy balance model (EBM) and a dynamic ice sheet model. The EBM would be used to study the interaction of geography variations and a seasonally varying snow line. This problem is important because of its possible relevance to the initiation of ice sheets during the onset of an ice age. In addition, the EBM would be compared to a dynamic ice sheet to simulate conditions leading to sudden growth decay of the ice sheet, thereby reproducing a long term model climate behavior that can be compared to the observed climate over the geologic time scale.
