Understanding and Modeling the Role of Horizontal Heterogeneity on the Dynamics of the Nocturnal Boundary Layer Across Scales

本研究旨在了解的作用，表面差异，在确定平均表面通量在夜间边界层（NBL）。 这些见解将用于开发新的基于物理的模型和参数化，这些模型和参数化可以适当地解释自然地表差异与地表附近大气最低层湍流之间的相互作用。 这项研究将包括一个数值天气预报（NWP）模块，作为夏令营的一部分，称为Hi-GEAR（女孩工程能力实现）和一个推广计划，称为发现工程。 本研究的关键假设是，在NBL的分层条件下，表面异质性将本地化湍流通量水平和垂直，并将增强不同的表面状态，如温度区域之间的通量对比。 所提出的研究的独特性在于这样一个事实，即目前的表面通量参数化模型不考虑这些相互作用。

This study seeks to understand the role of surface differences in determining average surface fluxes in the nocturnal boundary layer (NBL). Insights will be used to develop new physically-based models and parameterizations that can properly account for the interaction between natural land surface differences and turbulence in the lowest layer of the atmosphere near the surface. This study will incorporate a numerical weather prediction (NWP) module as part of a summer camp called Hi-GEAR (Girls Engineering Abilities Realized) and an outreach program called Discover Engineering. The key hypothesis of this study is that under the stratified conditions characteristic of the NBL, surface heterogeneity will localize turbulent fluxes horizontally and vertically, and will enhance the flux contrast between regions with different surface states, such as temperature. The uniqueness of the proposed research rests with the fact that current surface flux parameterizations in models do not account for these interactions.
