Investigation of Mountain Waves in the Mesosphere over the Andes Mountains
… purpose of investigating the atmospheric gravity waves generated when low level wind blows over the high mountains (referred to as Mountain Waves). These types of waves are a special case of atmospheric gravity waves, which carry significant momentum and exert strong forcing to the background …

Two Problems in Computational Wave Dynamics: Klemp-Wilhelmson Splitting at Large Scales and Wave-Wave Instabilities in Rotating Mountain Waves
… instabilities in nonhydrostatic and rotating mountain waves. The use of Klemp-Wilhelmson (KW) time splitting for large-scale and global modeling is assessed through a series of von Neumann accuracy and stability analyses. Two variations of the KW splitting are evaluated in particular: the …

Dynamic and Thermodynamic Controls on the Amount and Distribution of Orographic Precipitation
… the amount and distribution of precipitation in mountainous terrain. In Chapter 2, linear theory and numerical simulations are used to investigate how the tropopause affects the vertical structure of mountain waves, and in turn orographic precipitation. In idealized numerical simulations, …

Modification of Precipitation in Mid-Latitude Cyclones Passing over a Coastal Mountain Range
As mid-latitude cyclones pass over a coastal mountain range, the processes producing their clouds and precipitation are modified, leading to considerable spatial variability in precipitation amount and composition. Surface, radar, and aircraft observations from the 2015-16 Olympic Mountains …
