Abstract |
---|
The thinness of Earth?s atmosphere introduces two different ways of exploiting the turbulence characteristics. A first approximation is to study two-dimensional turbulence, which is interesting on its own, due to decades of theoretical development but lagging numerical support. Another approximation is to treat the problem as quasi-3D, with a stretched vertical coordinate. Accordingly, a number of simulations have been performed at a variety of computer clusters in Sweden. The talk will give a short introduction to 2D- and QG3D-turbulence, but the main focus will be on the numerical methods. |
