Animation of Clouds Based on the Interpolation of Weather Forecast Data

Abstract

We present a novel algorithm for interpolating discrete cloud data of numerical weather forecasts over time. The interpolation provides a continuous natural transition of the cloud properties over time intervals of several hours. A diffusion-free advection scheme transports cloud properties through the wind field. The algorithm is designed to be embedded in a rendering loop and provides the basis for employing cloud modeling techniques for creating temporal cloud animations of the future weather.
