Coastal marine environments are regions of significant meteorological interest as a result of the direct impact of atmospheric processes on, for example, commerce and trade, naval operations, and civilian activities. Because the coastal topography of the Western United States acts as a lateral boundary for the marine layer over the Northeastern Pacific Ocean, it plays a critical role in the life cycle of various marine boundary layer (MBL) processes. The work presented here will investigate two MBL phenomena - namely hydraulic jumps and coastally trapped disturbances (CTDs) - that are strongly influenced by coastal terrain and highlight the influence of large-scale meteorological conditions on meso- and micro-scale processes. The first portion of this research focuses on a case study of an atmospheric hydraulic jump offshore California on 24 May 2012. Observations from the University of Wyoming King Air are compared with simulations using the Weather Research and Forecasting (WRF) model. A sharp thinning of the upstream MBL and the downstream development of a hydraulic jump was captured by both the aircraft and the WRF model. Numerical simulations reveal that a strongly divergent wind field, consistent with expansion fan dynamics, is present upwind of the hydraulic jump. Results from large-eddy simulations show a large increase in the turbulent kinetic energy field in the jump region. Part two of this study investigates 23 CTD events - spanning the years from 2004 to 2016 - from a climatological perspective using several data products, including model reanalyses, buoys, and satellites. For the first time, satellite retrievals suggest that CTD cloud decks may play a unique role in the radiation budget due to a combination of aerosol sources that increase cloud albedo by ∼2% on average. Three of the 23 CTD cases are examined in more detail using aircraft and satellite measurements in addition to the WRF model. A set of WRF configurations suggests that the treatment of model physics strongly influences CTD cloud field evolution. Moreover, cloud water-soluble ionic composition analyses conducted for two of the CTD cases indicate that continental aerosol sources may impact CTD cloud decks.
