Modeling of the Tropical Atmosphere-Ocean System

这项研究涉及热带大西洋地区气候变率的模拟研究。工作假设是，大西洋和周围陆地的气候变率是由内部变率之间的相互作用决定的，内部变率将大气耦合到海洋，外部强迫来自热带大西洋地区以外。 工作的第一部分将处理厄尔尼诺/南方涛动的远距离影响对热带大西洋区域的具体影响。PI旨在了解整个ENSO生命周期的热带太平洋强迫如何影响热带大西洋部门的降水，风和海面温度。这项工作将侧重于热带大西洋大气和海洋相互作用造成气候多变性的耦合机制。PI将研究这些内部耦合机制如何与ENSO和北大西洋涛动提供的外部强迫相互作用。这项研究将使用大气、海洋和耦合的大气环流模式进行。这项工作很重要，因为它将增加我们对热带大西洋气候变化和可预测性的了解。这可能具有重要的社会效益。

This research involves a modeling study of climate variability in the tropical Atlantic sector. The working hypothesis is that climate variability over the Atlantic Ocean, and the surrounding land masses, is governed by an interaction between internal variability which couples the atmosphere to the ocean and external forcing from outside the tropical Atlantic region. The first part of the work will address the specific impact that the remote effects of ENSO have on the tropical Atlantic region. The PIs intend to understand how the tropical Pacific forcing throughout the ENSO lifecycle impacts the precipitation, winds and sea surface temperature in the tropical Atlantic sector. This work will focus on coupled mechanisms by which the tropical Atlantic atmosphere and ocean interact to create climate variability. The PIs will examine how these mechanisms of internal coupling interact with the external forcing provided by ENSO and the North Atlantic Oscillation. The research will be undertaken using atmosphere, ocean, and coupled general circulation models. The work is important because it will increase our understanding of climate variability and predictability in the tropical Atlantic. This could have important societal benefits.
