Abstract
  • Warm, high pressure systems are measured from a weather station on a high elevation peak in the Oregon Coast range during the winter months. Temperature observations on Mary’s Peak show abnormally warm air in relation to the surrounding areas. The goal of this study was to characterize the frequency and duration of these warm events around the Oregon Coast range during the cold season between November and February, determine how widespread they were, and to determine the background meteorological conditions which give rise to them. Temperature, relative humidity, height and wind were the main variables of data collected from radiosonde soundings, satellites and various weather stations. These sources showed wind directions, pressure systems, cloud formation and possible inversions which furthered the understanding of how and where the warm air formed. Analyses of the vertical structure of temperature and wind from the National Center for Atmospheric Prediction’s (NCEP) North American Regional Reanalysis (NARR) provided high resolution depictions of what occurred during these warm periods. The anomalous warm events that were observed affecting the summit of Mary’s Peak are likely caused by strong subsidence of warming air in the centers of high pressure ridges. These subsidence inversions may be originating from the semi-permanent North Pacific High pressure system at lower latitudes.
