STUDY ON RELATIONSHIP BETWEEN RED TIDE OF YEAR 2002 IN GUANGDONG COASTAL WATER AND THE MARINE HYDROMETEOROLOGY
摘要
Abstract
Relationship between the onset of red tide and the marine hydrometeorology was studied based on .the in-situ data of red tide and the measurement of marine hydrometeorology elements in Guangdong coastal water during January 2001 to December 2002. It was found that red tide could still take place even under the existence of scale 6 wind field in Dawanshan marine area. The fastest propagation of Skeletonema costatum and Gyrodinium instriatum occurred under the following conditions: water temperature 27.51 ~ 29.81 ℃, salinity 20.06 ~ 31.94, air temperature 22.7 ~30.4 ℃, wind speed 0.3~ 12.0 m/s, air pressure 995.9 ~1 002.0 hPa and the relative humidity 72% ~ 98%. Reduce of wind speed and air pressure, increase of water temperature and salinity, and the decrease of precipitation were found to be the marine environmental inducement of red tide onset. It was also revealed that the El Ni(n)o event in 2002 in the Equatorial Pacific, which induced the abnormal change of water temperature, salinity, wind speed, relative humidity and air pressure in the southeast coastal water of China and the precipitation of Guangdong Province, had an important impact on the red tide occurrence and development.关键词
