The atmospheric stability and its classifying schemes in terms of the Pasquill A-F classes have been analyzed by using the data obtained from a 100m tower located in the coastal area of Guangdong Province, China. Wind and temperature sensors were mounted on the tower at 10, 25, 50, 75, 100m levels respectively. Radiation sensors were mounted only at the ground level. Hourly averaged values of total radiation, net radiation, wind speed and standard deviation of horizontal wind direction, as well as temperature and vertical temperature difference were obtained over the period from December 1, 1992 to November 30, 1993. The results indicate that the atmospheric stability in the coastal region should be considered in terms of ground level stability (GS), vertical stability (VS) and horizontal stability (HS). The GS can be determined by the Pasquill-Turner method, the VS determined by the temperature lapse-rate and the HS determined by the - method.
