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.

山气象过程涵盖了广泛的相互作用量表，这些量表引入了数值天气预测的挑战。实际上，在山区，在标准理论，测量技术，分析技术和参数化的意义上，例外通常是规则。在这个项目中，我们将尝试通过利用新的测量技术来攻击其中的一些现有困难，我们的团队将部署这些技术来研究物理过程，从微观尺度（即湍流的耗散量表，O（1mm））中的尺度上进行研究，以了解中等量表。我们将利用现场实验，新开发和最先进的仪器以及坡度流和吹雪的数值模拟的多方面方法来提高人们对山区流量物理的了解。
