Mountain meteorological processes cover a wide range of interacting scales that introduce challenges for numerical weather prediction. In fact, in mountainous regions, exceptions are often the rule in the sense that standard theories, measurement techniques, analysis techniques, and parameterizations are usually not strictly valid. In this project, we will attempt to attack some of these existing difficulties by taking advantage of new measurement techniques that our team will deploy to study physical processes over scales ranging from the microscale (i.e., dissipation scales of turbulence, O(1mm)) into the meso-gamma scale. We will gain improved understanding of flow physics in mountainous terrain through a multifaceted approach utilizing field experiments, newly developed and state-of-the-art instrumentation and numerical simulations of slope flows and blowing snow.

山区气象过程涵盖了广泛的相互作用的规模，引入数值天气预报的挑战。事实上，在山区，标准理论、测量技术、分析技术和参数化通常不是严格有效的，在这个意义上，例外往往是规则。在这个项目中，我们将试图利用新的测量技术来解决这些现有的困难，我们的团队将部署这些技术来研究从微观尺度（即，湍流耗散尺度，O（1mm））到中伽马尺度。我们将通过多方面的方法，利用现场实验，新开发的和最先进的仪器和斜坡流和吹雪的数值模拟，提高对山区流动物理学的理解。
