Abstract

Abstract

Based on wind field diagnostic model and atmospheric diffusion experimental data in winter and summer seasons of 1993 at Wentouzi region in the east of Liaoning Province, the horizontal wind field pattern at nuclear-power station is analyzed. The results indicate that there are three kinds of the horizontal wind fields in winter season: 1) southerly wind fields; 2) northerly wind fields; and 3) the nuclear-powered site is located between high pressure and low pressure, or the whole region is located in an averaged pressure field, while system wind flows weakly, mountain-valley wind flows obviously, and the surface wind field in this area is not obvious. There are four kinds of the horzontal wind fields in summer season: 1) southerly wind field; 2) land-sea wind field; 3) shear of wind field; 4) northerly wind field. This study provides the basic parameters and theoretical guidance for evaluating air-pollution in this region.
- Wind field diagnostic model;
- Horizontal wind fields;
