Jack Barth and collaborators have published a recent journal article entitled “Widespread and increasing near-bottom hypoxia in the coastal ocean off the United State Pacific Northwest”. This article shows that ocean oxygen concentrations have tended to decline over the historical record, with the summer of 2021 in particular featuring large areas with values low enough to be harmful to many marine animals.

Read moreThe Diurnal Cycle in Summer Temperatures in Washington State
Summer visitors to WA state are sometimes struck by how cool it is during the late night and early morning hours, and how late in the day it stays warm. This can be especially the case during our hottest weather, when peak temperatures often occur at 5 to 6 PM local time.

The Summit at Snoqualmie Pass has the lowest base elevation (2,840’) of any ski resort in the western US. Given its low elevation and proximity to the Pacific Ocean and hence maritime air masses – the mean 850 hPa flow during winter is from the southwest at about 5 m/s – how is it cold enough to stay in business?
