Summertime low clouds are common in the Pacific Northwest (PNW), but spatiotemporal patterns have not been characterized. We show the first maps of low cloudiness for the western PNW and North Pacific Ocean using a 22‐year satellite‐derived record of monthly mean low cloudiness frequency for May through September and supplemented...
In common with much of the western United States, the Pacific Northwest (defined in this paper as Washington and Oregon) has experienced an unusual number of droughts in the past decade. This paper describes three of these droughts in terms of the precipitation, temperature, and soil moisture anomalies, and discusses...
The physical controls of snowmelt in the Pacific Northwest (PNW) are poorly
understood. While there have been numerous field and modeling investigations at the
plot and watershed scale, few studies have identified how the snow energy balance
(EB) components vary in importance both spatially and temporally. The identification
of how...
This research is concerned with the current debate among Oregonians on how to improve the standard of living and accelerate economic development in Oregon. The main question is what economic activities make Oregon, and regions within Oregon grow? To find out where Oregon's economic strength and weaknesses lie, first we...
We investigated the effects of climate on the growth of red alder across a broad latitudinal gradient and over a wide range of growing conditions in the Pacific Northwest of North America (PNW). Data for this study came from a study established in 1988 that includes 31 research installations located...
Both the structure and composition of naturally generated early-seral forests in the Pacific Northwest (PNW) can be profoundly different than that of more developed forest seres, especially in the period after a major disturbance but before conifers re-develop a closed canopy. While it is reasonable to suggest that the unique...
The spread of invasive species into the Pacific Northwest (PNW) of the United States poses a serious threat to the valuable forest resources of the region. Many insects and diseases that are a threat to these forest resources can be transported inside firewood. When campers transport their firewood across borders...
Increased temperatures and changes in precipitation will result in fundamental changes in the
seasonal distribution of streamflow in the Pacific Northwest and will have serious implications for water
resources management. To better understand local impacts of regional climate change, we conducted
model experiments to determine hydrologic sensitivities of annual, seasonal,...

Across the western US, the two most prevalent native forest insect pests are mountain pine beetle (MPB; Dendroctonus ponderosae; a bark beetle) and western spruce budworm (WSB; Choristoneura freemani; a defoliator). MPB outbreaks have received more forest management attention than WSB outbreaks, but studies to date have not compared their...
