Analysis on characteristics of pollution layer on the North Coast of Liaodong Bay
By using meteorological data in the pollution boundary layer which was observed in two ground observation sites:coast and land on the north coast of Liaodong bay during January-February in 2007,the daily change characteristics of pollute boundary layer in winter in the area were discussed.The results showed that the pollute boundary layer on the north coast of Liaodong bay was affected by the sea and land.In the certain weather condition,maybe the sea-land breeze appeared in the low altitude which was below 200 m in the coastal zone.The stability change in the different height in the coastal zone was more stable than in the land zone,and the wind field change in the area was mainly in 300 m low altitude.At night,the temperature inversion often appears in the area,and the thickness of temperature inversion layer is stably during 200-300 m.The thermal internal boundary layer penetrated deeply into the land about 10 km,and the height could reach 800 m.The atmospheric diffusion ability in the coastal area was weaker and stronger in the land area.
