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

该奖项的目的是从夏威夷群岛的地点重建全新世期间区域水文气候条件的变化，以研究这些变化与太平洋气候变率的主要模式的变化之间的关系。该项目的主要目标是探索北太平洋环流如何响应外部强迫，以及是什么导致了平均气候状态的低频变化和夏威夷群岛周围高频变化的变化。这一目标将通过使用SynTraCE-21新导出的水文气候古气候数据和现有的瞬态古气候模式模拟来解决。开发新的代理数据是填补热带海洋古气候记录与周围大陆档案之间空白的重要一步。该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。夏威夷群岛是这项研究的一个好地方，因为它们位于哈德利环流的下降分支之下，这个区域提供了对热带-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。这种模式数据比较的结果可能是评估全新世中期北太平洋气候重建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.
