Climate models predict a gradual weakening of the North Atlantic meridional overturning circulation (MOC) during the twenty-first century due to increasing levels of greenhouse gas concentrations in the atmosphere. Using an ensemble of 16 different coupled climate models performed for the Fourth Assessment Report (AR4) of the Intergovernmental Panel on...
Studies using International Satellite Cloud Climatology Project (ISCCP) data have reported decreases in cloud optical depth with increasing temperature, thereby suggesting a positive feedback in cloud optical depth as climate warms. The negative cloud optical depth and temperature relationships are questioned because ISCCP employs threshold assumptions to identify cloudy pixels...
Isopycnal slope spectra were computed from thermistor data obtained using a microstructure platform
towed through turbulence generated by internal tidal motions near the Hawaiian Ridge. The spectra were
compared with turbulence dissipation rates ε that are estimated using shear probes. The turbulence subrange
of isopycnal slope spectra extends to surprisingly...
Horizontal tow measurements of internal waves are rare and have been largely supplanted in recent
decades by vertical profile measurements. Here, estimates of isotherm displacements and turbulence dissipation
rate from a towed vehicle deployed near Hawaii are presented. The displacement data are interpreted
in terms of horizontal wavenumber spectra of...
A timber sale is the culmination of many years
of forest management. For many woodland
owners, it is the most significant opportunity
for return on their forestry investments. It also
may be a significant departure from their normal
sphere of operations. Owners may be accustomed
to planting, managing weeds, thinning...
