A quasi-one-dimensional numerical mode1 containing a prognostic turbulent kinetic energy parameterization and simplified approximations to horizontal gradients is used to study interactions of thermally induced nocturnal slope flows with following and opposing ambient winds. It is found that a following ambient wind causes the peak perturbation wind to be weaker and to be realized at a greater ...

Kolmogorov second-order structure functions are used to quantify and compare the small-scale information contained in near-surface ocean wind products derived from measurements by ASCAT on MetOp-A and SeaWinds on QuikSCAT. Two ASCAT and three SeaWinds products are compared in nine regions (classified as rainy or dry) in the tropical Pacific between 10 S and 10 N and 140 and 260 E for the period...

This paper investigates the steps necessary to achieve accurate simulations of flow over steep, mountainous terrain. Large-eddy simulations of flow in the Riviera Valley in the southern Swiss Alps are performed at horizontal resolutions as fine as 150 m using the Advanced Regional Prediction System. Comparisons are made with surface station and radiosonde measurements from the Mesoscale Alpine ...

Seasonal changes and vertical mixing processes in the upper layers of the North Atlantic Ocean are simulated with a basin-scale sigma coordinate ocean model that uses the Mellor-Yamada turbulence closure scheme. The cause of insufficient surface mixing and a too shallow summertime thermocline, common problems of ocean models of this type, is investigated in etail by performing a series of sensi...

Agent adaptability – the ability of agents to change behavioral strategies when it is beneficial to do so – is presumed to be an important part of the robustness of complex adaptive systems (CAS). But, determining when changing behaviors is advantageous for agents has proven quite challenging in CAS research, as sometimes behavioral change is necessary, but other times it can impose costs that ...

Internal wave packets propagating vertically in the oceanic thermocline are investigated with numerical simulations. For a typical set of environmental and packet parameters, it is shown that linear dispersion will have a significant effect on the spreading and decay in amplitude of these packets. Sufficiently strong packets are shown to generate turbulence that forms a continuous ‘scar’ of sma...

model that examined the effects of socialization rate, turnover, and environmental turbulence (or uncertainty) on sharing of beliefs. March’s model did not incorporate organizational features such as structure, tasks, and members’ interactions. Harrison and Carrol (1991) developed a model that examined organizational culture diffusion. Although

We demonstrate a method of representing a firm’s strategy as its position and movement within an n-dimensional strategy space. We explore this space through the use of an agent-based model and provide preliminary results as to the appropriateness of different strategies under differing levels of environmental turbulence.
