The role of stratified shear instability in maintaining the deep cycle of
turbulence immediately below the equatorial mixed layer is examined by means of
linear stability analysis. The Taylor-Goldstein equation is solved numerically, using
observed currents and stratification from the Tropical Instability Wave Experiment
(TIWE). Multiple unstable modes are found,...
We report the first measurements of CO₂, CH₄,
N₂O, CO₂, and H₂O(g) in the exhaust trails of T-39, B-757, and
DC-8 aircraft at cruise conditions. Emission indices (El)
derived from these in-situ measurements are presented.
Results are in agreement with ground-based tests indicating
aircraft act as a net sink for...
Harvesting costs were determined for commercial thinning of young stands to
achieve vegetation and wildlife objectives. This included replicated comparisons of
thinning treatments. Treatments were defined based on residual tree stocking after
thinning. Study procedures were developed and evaluated to improve statistical
relevance. Multiple linear regression models were used to...
