Characteristics and Causes Analysis of Storm Surges under the Effect of Cold Air Outbreaks in the Bohai Sea
Lei Huang and Wenhai Xiong
Abstract—Based on the synchronous tidal data observed
from 12 tide stations of the Bohai Sea in a year, the
characteristics and causes of storm surges under the effect of
cold air outbreaks have been analyzed using the method of
harmonic analysis. The results show that the phenomena of
abnormal sea-level events are affected remarkably by strong
winds due to landform of the Bohai Sea. Under the effect of
north and northwest winds, negative storm surges appear
successively in the northern part of the Bohai Sea, and in the
southern part of the Bohai Sea, first positive storm surges
appear and then negative storm surges appear successively.
After the wind direction has changed into southerly, the values
of negative storm surges decrease gradually, until positive
storm surges appear at the tide stations of the Bohai Sea. In the
final analysis, maximum negative storm surges or maximum
positive storm surges appeared at the tide stations in the
southern part of the Bohai Sea lag than that in the northern
part. Therefore, in order to provide beneficial service for
marine activities, the mariners should pay attention to the
positive storm surge on the high water and to the negative storm
surge on the low water.
