P2C2:Collaborative Research: Data-Model Comparison of Holocene Pacific Hydroclimate Variability on the Hawaiian Islands Using Geochemical Records and SynTraCE-21 Simulations

这一奖项的目的是重建夏威夷群岛全新世期间区域水文气候条件的变化，以调查这些变化可能如何与太平洋气候变化的主要模式的变化有关。该项目的主要目标是探讨北太平洋环流如何对外部强迫作出反应，以及是什么导致夏威夷群岛周围平均气候状态的低频变化和高频变化的变化。这一目标将通过使用新获得的水文气候古气候数据和来自SynTraCE-21的现有的瞬变古气候模型模拟来实现。开发新的替代数据是填补热带海洋古气候记录与周边大陆档案之间空白的重要一步。这个项目将有助于更好地了解风暴路径的强度和位置，并为博士后学者和研究生提供支持。夏威夷群岛是进行这项研究的好地点，因为它们位于哈德利环流的下降分支之下，该地区提供了对热带-热带外气候联系的见解，并有可能为热带外风暴活动提供新的见解。这一模式数据比较的结果可能是评估中全新世期间重建北太平洋气候的信心的关键组成部分。

The objective of this award is to reconstruct changes in regional hydroclimatic conditions during the Holocene from sites on the Hawaiian Islands to investigate how these changes might be related to variations in the dominant modes of climate variability over the Pacific. The primary goal of the project is to explore how the North Pacific circulation responded to external forcing and what caused low-frequency variations of the mean climate state and changes in the high-frequency variability around the Hawaiian Islands. This goal will be addressed by using newly derived hydro-climate paleoclimate data and existing transient paleoclimate model simulations from SynTraCE-21. The development of new proxy data is an essential step towards filling the gap between tropical marine paleoclimate records and archives from the surrounding continents. This project will aid in a greater understanding of storm track strength and location, as well as providing support for post-doctoral scholars and graduate students.The Hawaiian Islands are a good site for this research because they are located under the descending branch of the Hadley circulation, a region that offers insights into the tropical-extra-tropical climate connection and has the potential to provide new insights into extra-tropical storm activity. The results from this model-data comparison could be a critical component in assessing the confidence in the reconstruction of the North Pacific climate during the mid-Holocene.
