Controlling the Global Weather
The key factor enabling control of the weather is that the atmosphere is sensitive to small perturbations. That is, it is the very instability of the atmosphere’s dynamics that makes global weather control a possibility. The Earth’s atmosphere may be chaotic, and very likely is very sensitive to small perturbations. Certainly very simple nonlinear dynamical models of the atmosphere are chaotic,...
متن کامل4DVAR for Global Atmospheric Numerical Weather Prediction
The long-term goal of this RTP project is to provide the warfighter with superior battlespace environmental awareness in terms of high fidelity four-dimensional (4D) depiction of the global atmospheric state. This situational awareness is a key aspect of information superiority in the DoD’s strategic plan to ensure battlespace dominance in the 21 century. This goal is to be accomplished by prov...
متن کاملParallel geometric multigrid for global weather prediction
The subject of this work is an optimal and scalable parallel geometric multigrid solver for elliptic problems on the sphere. The use of fast elliptic solvers is crucial to the forecasting and data assimilation tools used at the UK Met Office, and the preconditioned Krylov subspace solvers currently used do not perform well for large problem sizes due to the ill-conditioned nature of the problem...
متن کاملGlobal climate change: predicting the weather.
In Greek mythology, Prometheus stole fire from the gods and gave it to humans. His action infuriated Zeus, who then chained the giant to a rock in the ocean where he was lashed by the seas and burned by the sun. Today, humans' ability to capture energy and use it as we wish may be leading us toward a similar fate. Records from glacial ice cores and direct air sampling confirm that since the ind...
متن کاملEstimating and Correcting Global Weather Model Error
The purpose of the present study is to explore the feasibility of estimating and correcting systematic model errors using a simple and efficient procedure, inspired by papers by Leith as well as DelSole and Hou, that could be applied operationally, and to compare the impact of correcting the model integration with statistical corrections performed a posteriori. An elementary data assimilation s...
