    Notes: Abstract A quasi-wavelet based numerical method was introduced for solving the evolution of the solutions of nonlinear paritial differential Burgers' equations. The quasi wavelet based numerical method was used to discrete the spatial derivatives, while the fourth-order Runge-Kutta method was adopted to deal with the temporal discretization. The calculations were conducted at a variety of Reynolds numbers ranging from 10 to unlimited large. The comparisons of present results with analytical solutions show that the quasi wavelet based numerical method has distinctive local property, and is efficient and robust for numerically solving Burgers' equations.

    Notes: Summary  In the central region of Taiwan, ozone episodes occur most often during autumn. Two field experiments were conducted during the autumns of 1998 and 1999 to analyze the vertical profile of the boundary layer and determine its effects on ozone concentration over the region. The vertical virtual potential temperature and wind profiles were derived from tethersonde data. The NOx, NMHC and O3 concentration vertical profiles were monitored up to a height of 500 meters using black-covered Teflon tedler sampling bags. During the experimental periods, nighttime terrestrial long wave radiation could cause the inversion height to reach 500 meters by the following morning. It was shown that these types of synoptic structures suppress the vertical diffusion of NOx, NMHC and O3. During the daytime, measurements indicate that pollutants were well mixed in the upper portion of the mixing layer. At night, the ground level ozone concentration was on the decrease but increased with altitude to a height of 500 m. The NOx decreased with altitude whereas the NMHC showed no significant variations.
