Which statement about HySplit is NOT true?

Which statement about HySplit is NOT true?

• A. It is a computer model
• B. It computes air parcel trajectories
• C. It performs simple linear dispersion simulations only
• D. It models complex dispersion simulations

Answer: (C)

HySplit is a flexible dispersion modeling tool that combines trajectory calculations with puff-based dispersion to simulate how a release spreads in the atmosphere. It uses wind fields from meteorological data to move air parcels and to represent how a plume evolves, including vertical structure, turbulence, and interactions with terrain. Because of this, HySplit can handle not only simple scenarios but also complex dispersion cases. It can perform trajectory calculations and run puff-based simulations that account for varying winds, vertical mixing, and other atmospheric processes. Saying it only does simple linear dispersion misses what HySplit is built to do. So the statement claiming HySplit performs simple linear dispersion only is not true, since HySplit supports more advanced, complex dispersion modeling in addition to basic trajectory computation.
