A Semi-Lagrangian Contouring Method for Fluid Simulation From the paper by Bargteil, AW, Goktekin, TG, O'Brien, JF, Strain, JA, "A Semi-Lagrangian Contouring Method for Fluid Simulation." ACM Transactions on Graphics, 25(1):19--38, January 2006. The authors present a semi-Lagrangian surface tracking method for use with fluid simulations. Their method maintains an explicit polygonal mesh that defines the surface, and an octree data structure that provides both a spatial index for the mesh and a means for efficiently approximating the signed distance to the surface. At each timestep a new surface is constructed by extracting the zero set of an advected signed-distance function. Semi-Lagrangian backward path tracing is used to advect the signed-distance function. One of the primary advantages of this formulation is that it enables tracking of surface characteristics, such as color or texture coordinates, at negligible additional cost. The video includes several examples demonstrating that the method can be effectively used as part of a fluid simulation to animate complex and interesting fluid behaviors.

Real Time 3D Fluid and Particle Simulation and Rendering This application uses a GPU based 3D fluid solver with a moving domain to seamlessly advect hundreds of thousands of particles. We use a globally second-order accurate fluid simulation method which takes constant calculation time, leading to a highly turbulent but stable simulation suitable for use in a real-time situation. In this demo our solver is used to simulate the turbulent wake behind a car, and we render smoke transported through that wake with a hardware-based volume renderer. The simulation domain is at a fixed position relative to the car, and we exploit Galilean invariance to transform the moving simulation domain into a motionless domain with inflow and outflow boundary conditions. Particles are advected through this fluid, but seamlessly transition to simple Newtonian dynamics as they leave the simulation domain. After simulation, the particles are sorted using a GPU-accelerated radix sort, and then rendered as alpha blended sprites with motion blur and volumetric shadows.

Meteorology Tutorial- Synoptic Scale Baroclinity Synoptic Scale Baroclinity *Keep in mind that the northern hemisphere polar front is the one that I am using as an example in the following. Cold air advection from the poles moves southward and adiabatically warmed sinking air advecting northward, helps create a substantial temperature gradient along the polar front. Albeit there is a strong temperature gradient along the polar front and the ITCZ, the temperature gradient anatomy is quite different. At the ITCZ, the temperature is lower at both sides and is the highest at the ITCZ itself, causing air from both sides to converge into it and rise evenly. At the polar front however, the temperature to the south of the baroclinic boundary is higher than the one to the north. As a result, the colder air from the north slides beneath the warmer air, forcing the more buoyant warmer air aloft. This induces thermodynamic fluxes incessantly hither and thither at the mid latitude regions. That is the primary reason why the majority of mid latitude cyclones form in close proximity to the polar front. And as many of you know, a significant synoptic scale cyclone is often associated with anomalously high temperatures at its right side and cooler than temperatures at the left side due to the counterclockwise rotation. Part II B) The Polar front and the Jet stream The polar front also affects the thickness of the atmosphere—the side with the higher temperatures have higher thickness values, while the side with the lower temperatures has ...
