How does subgrid-scale parametrization influence nonlinear spectral energy fluxes in global NWP models?

How Does Large-scale Wind Power Generation Affect Energy and Reserve Prices?

Intermittent nature of wind power faced ISO and power producers with new challenges. Wind power uncertainty has increased the required reserve capacity and deployment reserve. Consequently, large-scale wind power generation increases ISO costs and consequently reserve prices. On the other hand, since wind power producers are price taker, large-scale wind power generation decreases residual dema...

Numerical analysis of the nonlinear subgrid scale method

This paper presents the numerical analysis of the Nonlinear Subgrid Scale (NSGS) model for approximating singularly perturbed transport models. The NSGS is a free parameter subgrid stabilizing method that introduces an extra stability only onto the subgrid scales. This new feature comes from the local control yielded by decomposing the velocity field into the resolved and unresolved scales. Suc...

Data-based stochastic subgrid-scale parametrization: an approach using cluster-weighted modelling.

A new approach for data-based stochastic parametrization of unresolved scales and processes in numerical weather and climate prediction models is introduced. The subgrid-scale model is conditional on the state of the resolved scales, consisting of a collection of local models. A clustering algorithm in the space of the resolved variables is combined with statistical modelling of the impact of t...

Data-driven stochastic parametrization for subgrid-scale tropical convective area fraction

How Does Energy Intake Influence the Levels of Certain Steroids?

The influence of steroid hormones on food intake is well described. However, there are only a few studies on the effect of food intake on steroid levels. The study involved eight non-smoker women (average age 29.48±2.99 years; average BMI 21.3±1.3 kg/m2); they did not use any kind of medication affecting steroidogenesis. We analysed the influence of four various stimuli on the levels of steroid...
