The warm pool region of the western tropical Pacific is of particular interest to atmospheric dynamics because it represents a significant source of energy to the atmosphere. A better understanding of heat transfer driven by mesoscale and turbulent circulations within this region could lead to improved global circulation models, and...
The climate and the exchange of heat between atmosphere and
ocean are examined in a region adjacent to Washington and Oregon,
and in two sub-regions adjacent to Oregon. The sub-regions are
chosen such that one contains the nearshore upwelling region and the
other borders it on the seaward side.
The...
Atmospheric boundary layers become stably stratified at night over land when the surface becomes colder than the air layer above. In stable nocturnal boundary layers (SNBL), turbulence becomes weak and intermittent, terrain-induced phenomena such as drainage currents or gravity-waves emerge and the surface heterogeneity is enhanced. Because of their complexity...
A thermal infrared (TIR) camera is used to remotely sense the foliage temperature in a mountain valley. The foliage temperature is used as a proxy for air temperature and can be used to study and map the dynamics of the nocturnal, weak-wind boundary layer in this valley. All radiative flux...
Two tributaries of the south fork of the Burnt River, near Unity Oregon were studied
during the summers of 2000 and 2001 to determine water heating and cooling
patterns. Hourly temperature data were recorded for air, water, and soil parameters
at four elevations 150m apart on Barney and Stevens Creeks....
Air temperatures at i m and soil temperatures at 2C cm are reported for
twenty-one forest stands in the central Western Cascader of Oregon. Records
began in 1970 for some stands, in 1971 or 1972 for most. Temperature Growth
Index for a stand, based on temperature effects on Douglas-fir seedling...
Since plants utilize CO₂ as the substrate for photosynthesis, terrestrial plants
may be directly affected by increasing levels of CO₂ in the atmosphere. Plants native to
the sagebrush steppe are predicted to increase in growth in response to elevated CO₂
through increased water use efficiency and higher photosynthetic rates. This...
In a steady state, the Earth's absorbed solar radiation (ASR) balances the outgoing
longwave radiation (OLR) at the top of the atmosphere (TOA). In response to a radiative
forcing, that is, an external perturbation to the top of the atmosphere energy balance, the
Earth's climate system adjusts until reaching a...
This report presents observations from a single mooring of velocity, temperature, conductivity, and pressure, made as part of the Ocean Storms experiment, conducted in the N.E. Pacific Ocean (47° 25.4' N, 139° 17.8' W) from August 1987 to June 1988. The mooring contained a total of 14 current meters, 4...
