Realizations – Do They Matter?
Yes if there is
- Geographic variation. Effect because of wind meander
- Time effects, such as for
- Human decisions or responses (e.g., warning and reporting, simulation-based training)
- Automated responses (e.g., detectors)
Dispersion scales with distance
- Structure of dispersion far downwind cannot be ignored
The Gaussian ensemble average is not a plausible realization
- Suitable for hazard assessment applications
- Inappropriate for some M&S applications
