Meteorological conditions of Enteromorpha Prolifera outbreak and its movement in Qingdao seashore from 2008 to 2010
Based on the monitoring information of Enteromorpha Prolifera from 2008 to 2010,characteristics of at-mospheric circulation,hydro-meteorological elements during Enteromorpha Prolifera outbreak period were ana-lyzed and dynamics mechanism of movement of Enteromorpha Prolifera to the seashore of Qingdao was ex-plained.The results show that the high over the sea instead of the high over the land controlling the Yellow Sea is the key for Enteromorpha Prolifera movement to the north.Sunshine duration increases sharply after continuous rain and fog weather,which is favorable to the blooming of Enteromorpha Prolifera.Surface current is driven and controlled by sea surface wind at offshore of Qingdao in summer.Wind becomes a key element for Enteromorpha Prolifera movement and accumulation at Qingdao seashore after Enteromorpha Prolifera drifts to the south of Qingdao.The change of wind can lead to different drift tracks of Enteromorpha Prolifera.In 2008 and 2010,Enter-omorpha Prolifera moves to the Qingdao seashore along the northwest direction under the situation of lasting southeast wind and ashore current along southeast-northwest direction,and then Enteromorpha Prolifera accumu-lates at the seashore driven by wind southerly.On the other hand,there is largely part of westerly wind and surface current paralleling with the coastline in 2009,and Enteromorpha Prolifera at the south of Qingdao turns to the east.As a result,Enteromorpha Prolifera causes little impact to Qingdao.
