| Abstract | The objective of this study is to identify advection schemes with more desirable properties for air quality modeling. The performances of the following eight schemes are evaluated: (1) Smolarkiewicz' scheme, (2) piecewise parabolic method, (3) Bott's scheme, (4) Yamartino's schemes, (5) flux-corrected transport, (6) the semi-Langrangian method, (7) chapeau function scheme, and (8) accurate space derivative scheme. The evalaution cases are selected from idealized problems with known analytic solutions, Problems relevant to air quality modeling are preferred such as one-dimensional advection with uniform velocity, rotation of a cone-shaped puff, skew advection of a point-source plume, shear flow tests and rotation of chemically reactive puffs. Quantitative measures are used in the evaluation so that properties of different schemes can be compared readily. |
