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取得了迅速进展，但仍有很多东西需要学习，许多气候模型仍然难以模拟热带天气系统。该项目的目标是利用最近开发的。理论来制定一系列有针对性的标准，以确定控制热带系统的关键物理过程。这些标准将用于评估气候模型中马登-朱利安涛动和热带低压类扰动的表现。将阐明水的重要性热带天气系统中的蒸汽与云的相互作用，目前气候模型中尚未很好地捕捉到这种相互作用，并且将找到改进我们当前对热带天气系统的理论思维的机会，除了培训学生和博士后外，这项工作还将创造机会。以名为“Tiempo, Clima y Tierra”的通俗易懂的播客形式为西班牙语使用者提供高质量的教育资源，并为本科生举办在线教育研讨会。自由对流层水蒸气在热带对流的发生和组织中发挥着重要作用。这种认识已经。导致我们对热带天气系统的理解取得了许多进展，其中一个进步是认识到“水分模式”可能存在，这是一种水蒸气在其演化中发挥核心作用的热带系统。此外，有证据表明水平。潮湿的静态能量平流可以在热带低气压类系统的发展和增长中发挥重要作用，从而导致“水分涡不稳定性”。该提案将利用我们对热带天气系统的理论理解的最新进展来开发一系列旨在识别湿度模式的标准和观测中被识别为湿度模式或由湿度涡不稳定性增长的系统的预算方程将与线性理论的结果进行比较，该分析的结果将用于评估 Madden- 的表示。该提案还将以通俗易懂的播客和面向本科生的在线教育研讨会的形式为西班牙语使用者提供高质量的教育资源。世界上使用最广泛的语言西班牙语是美国增长最快的口语之一，但缺乏涵盖地球科学不同主题的高质量教育资源。该奖项反映了 NSF 的法定使命，并被认为值得通过以下方式提供支持：使用基金会的智力价值和更广泛的影响审查标准进行评估。
