项目摘要

Expeditious advances in our understanding of tropical weather systems have been made during the last decade. However, there is still much to be learned, and many climate models still struggle to simulate the tropical weather systems. The goal of this project is to leverage recently developed theories to develop a series of criteria aimed at identifying the key physical processes that govern the tropical systems. These criteria will be used to evaluate the representation of the Madden-Julian Oscillation and tropical depression-like disturbances in climate models. The outcome of this study will elucidate the importance of water vapor-cloud interactions in the tropical weather systems, interactions that are currently not well-captured in climate models, and will identify opportunities to improve our current theoretical thinking of tropical weather systems. Along with training students and a postdoc, the work will also create high-quality educational resources for Spanish speakers in the form of a layperson-friendly podcast titled “Tiempo, Clima y Tierra” and educational online workshops for undergraduate students. Free-tropospheric water vapor plays an important role in the occurrence and organization of tropical convection. This realization has led to numerous advances in our understanding of tropical weather systems. One such advancement is the recognition that “moisture modes” may exist, a type of tropical system in which water vapor plays a central role in its evolution. Furthermore, there is evidence that horizontal moist static energy advection can play an important role in the development and growth of tropical depression-like systems, leading to “moisture-vortex instability.” This proposal will leverage these recent advancements in our theoretical understanding of tropical weather systems to develop a series of criteria aimed at identifying moisture modes and moisture-vortex instability in observations. Budget equations for the systems that are identified as moisture modes or growing from moisture-vortex instability will be compared with those from linear theory. The results of this analysis will be used to evaluate the representation of the Madden-Julian Oscillation and tropical depression-like waves in the various model simulations. The proposal will also produce high-quality educational resources for Spanish speakers in the form of a layperson-friendly podcasts and educational online workshops for undergraduate students. Even though Spanish is one of the most widely spoken languages in the world and one of the fastest-growing spoken languages in the US., there is a lack of high-quality educational resources that cover different topics of the geosciences in Spanish.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在过去的十年中，我们对热带天气系统的理解迅速发展。但是，仍然有很多东西可以学习，许多气候模型仍然很难模拟热带天气系统。该项目的目的是利用最近开发的理论来制定一系列标准，旨在确定控制热带系统的关键物理过程。这些标准将用于评估在气候模型中Madden-Julian振荡和热带抑郁症状的表示。这项研究的结果将阐明热带天气系统中水蒸气云相互作用的重要性，当前气候模型中目前尚未得到充分捕捉的相互作用，并将确定改善我们当前对热带天气系统的理论思维的机会。与培训学生和博士后一起，这项工作还将为西班牙使用者提供高质量的教育资源，形式为外行友好的播客，名为“ Tiempo，Clima Y Tierra”和本科生的教育在线研讨会。自由层水蒸气在热带结构的发生和组织中起重要作用。这种认识导致了我们对热带天气系统的理解的许多进步。这样的进步之一就是认识到可能存在“水分模式”，这是一种热带系统，其中水蒸气在其进化中起着核心作用。此外，有证据表明，水平水分静态能量广告可以在热带抑郁症状系统的发展和增长中发挥重要作用，从而导致“水分涡流不稳定性”。该建议将利用我们对热带天气系统的理论理解中的这些最新进步，以开发一系列旨在识别观测中的水分模式和水分涡流不稳定性的标准。将被识别为水分模式或从水分涡流不稳定性增长的系统的预算方程与线性理论的预算方程将进行比较。该分析的结果将用于评估各种模型模拟中Madden-Julian振荡和热带抑郁样波的表示。该提案还将以对外行友好的播客和本科生的教育在线研讨会的形式为西班牙语者提供高质量的教育资源。即使西班牙语是世界上口语最广泛的语言之一，也是美国增长最快的语言之一。但缺乏高质量的教育资源，涵盖了西班牙语中的地球科学的不同主题。该奖项反映了NSF的法规任务，并认为通过基金会的知识优点和广泛的cribia criperia crigatia crigitia crigitia criperia cripitia the Issportiation the奖项。
