This thesis develops a technique for the three-dimensional (3-D) display of clouds, topography and atmospheric surfaces on an image and graphics analysis system. Cloud heights were estimated from infrared satellite imagery. Software was written to translate two-dimensional gridded data height fields into gray shade images. Existing 3-D display software was modified to use the data images as input. Potential temperature and 500 mb surfaces are presented as examples of possible fields for analysis in 3-D. The software was further modified to expand the geographical area enclosed in the final 3-D images. These images were used to produce 3-D displays of topography, clouds and atmospheric parameters. The relationships between atmospheric surfaces and cloud structures can be more clearly seen in the 3-D representations. With modifications to increase the resolution of the 3-D displays, improved understanding of the atmosphere can be expected.
