A calculation method is considered that it is able to simulate atmospheric dispersion of ship exhaust. This calculation method is structured the following these elements: (1) estimation model of two dimensional wind based on SIMPLE (Semi-Implicit Method for Pressure-Linked Equation) with observed data, (2) calculation formula for amount of exhaust NOx based on total volume control manual and (3) discretized advection-diffusion equation based on Cell Automaton method. This simulation runs that diffusion of ship exhaust that sail inside Osaka Bay by using this calculation code which is combined these elements. The result confirms that ships move shipping route as time progresses and ship exhaust diffuse downwind while convect one. It is, consequently, exposed that this calculation method is available diffusion simulation of ship exhaust.
