Algorithms for three-dimensional visualization of atmospheric front surfaces have been developed. Previously, the technology of visualization of intersections of atmospheric fronts with isobaric levels was implemented. These are curves that show the intensity and type of the atmospheric front in color. At this stage, it was necessary a) to find out which curves at different levels correspond to the same two-dimensional surface in three-dimensional space; b) to build approximations of these surfaces. A significant problem for constructing the algorithm: the curves are not submitted analytically, but by pixels on a rectangle. Curves can branch. The developed algorithms use spline-approximation of curves and approximation by Bezier surfaces. The resulting surfaces can be "viewed" on the screen at different spatial scales and at different angles, i.e. simulated "exploration" of the surfaces of atmospheric  fronts. The initial information for this technology is the prognostic output of the COSMO-ru scheme. Therefore, the user will be able to monitor the dynamics of the surfaces of atmospheric fronts and their intensity to make operational decisions to optimize the flight trajectory.
