Most meteorologists probably use the climate data produced, not the program that produced the data. So the data producing program’s natural interface is simply the command to run it and the file system for storing results. The separation between simple interface for launching a big calculation vs. friendly software for using the results is sensible and common in at least two cases. 1. The data is calculated infrequently using lots of computing power & time. After which it is the data that is primarily used. 2. The data is calculated by one group. Many other groups just use the produced data. In climate calculations, I expect both cases apply.
