Over Salem, Oregon there is a marine polar airmass most of the year including May
Air masses form as air gathers in a specific area, and all the air has stable conditions such as a similar temperature and humidity. Air masses are often large as they cover multiple kilometers.
Moreover, the air masses can be:
- Marine
- Continental
- Tropical
- Polar
- Arctic
Salem, Oregon is in the west coast of the United States, in this area, the air masses are Marine due to the location near the ocean and Polar because the air is cold. Moreover, the location of this air mass is quite constant, this makes it likely the Marine Polar mass is over Oregon most of the days of the day.

Explanation:
The deformation of sedimentary strata in the American West during the Jurassic Period was caused by the Farallon plate subducting beneath the North American plate.
<h3>What purpose served the Farallon plate?</h3>
About 100 million years ago, the Farallon oceanic plate was placed between the diverging Pacific & North American plates, which later united to form the San Andreas fault. The Farallon was subducted beneath North America and then plunged deep into the mantle when those plates clashed, causing a significant component of the structure to disappear.
<h3>When did the Farallon plate go under the ocean?</h3>
50 million years ago, at the start of the series, the Farallon plate started to press against the North American continent, sinking beneath it and forming mountain ranges like the Rocky Mountains. The Farallon plate was subducting as a single unit along the entire length of North America, from Alaska down past Mexico.
