On the face of it, this would seem an extremely welcome capability to operational forecasters. Recent experience is discussed whereby using the LINUX port of the FSL D3D in an operational environment has convinced the author that many forecasters will need to rethink and refine their three dimensional conceptual models of atmospheric processes. Several questions are examined, including: 1) why do some operational forecasters have difficulty in interpretation of three dimensional displays of traditional meteorological variables? 2) how deeply has the classical two dimensional way of thinking of the past been ingrained into the psyche of operational forecasters? 3) does three dimensional (and four dimensional) visualization represent a true paradigm shift in viewing the atmosphere? 4) what can be done in the operational environment to ease the transition to three (and four) dimensional visualization? 5) how can academia and other teaching and training organizations facilitate this shift in visualization paradigms, and why must they? 6) what does the future of three dimensional visualization hold for the operational meteorologist?
