Inversions

Inversions

In Central Washington where the mountains fall to the Columbia River and the Columbia Plateau rises several thousand feet or more to the East there is a a weather phenomenon called, “Inversions” which can remain in place for days, weeks, and even months at a time resulting in cold, sunless days, and impenetrable fog sometimes thousands of feet thick and with it below normal temperatures, air stagnation, and ground level precipitation while simultaneously weather above the inversion layer at higher elevation in the atmosphere is often sunny and warmer. The normal atmospheric conditions generally in place become inverted as the graphics below indicate…

 

This is part of living in a topography of mountains and valleys and is astonishing to experience especially when you ascend up out of the inversion into blue skies, sunshine, and warm temperatures. The size, duration, and frequency of these inversions vary year to year but make for some interesting scenery resulting from freezing fog and it is surreal as you hike through the inversion and break on through to the other side especially when it’s into blue skies and sunshine with clear crisp mountain views. I have included some photographs from trips below, within, and above the inversions from over the years.
