Marys Peak Meteorology:
Marys Peak summits at 1250 meters and is the highest peak in Oregon's Coast Range. Marys Peak is often above the boundary layer of the surrounding terrain, although summer daytime boundary layers may reach heights of 2 km, in which case Marys Peak may generate a local boundary layer. When summer marine air penetrates from the Pacific Ocean 60 km to the west, it is usually confined to the lowest 500 m or less, such that Marys Peak is well above the marine air. Exceptions include marine air penetration with synoptic support (weak summer cold front). In these cases, marine stratus can be seen "flowing" over the top of the peak.
This webcam was funded by the National Science Foundation and installed by the Ocean Mixing Group on the roof of Burt Hall at Oregon State University as a part of experimental investigations into the physics of form drag in geophysical flows. The Biomicrometrology Group maintains the site as part of ongoing studies to understand and quantify interactions between the air, vegetation, and the land surface. The images obtained here are intended to complement studies of controlled flows over topographic obstacles in ocean and atmosphere.
