外文摘要：An extratropical cyclone reported to have the largest wind speed in Newfoundland in more than a decade landed on the island of Newfoundland on 11 March 2017. The oceanic responses in Placentia Bay on the southeast coast of Newfoundland to the winter storm were examined using observed data and the Finite-Volume Community Ocean Model (FVCOM). The peak non-tidal water level increase, i.e., storm surge, reached 0.85 m at St. Lawrence and 0.77 m at Argentia on Placentia Bay. Sea surface temperature slightly decreased after the storm passage according to buoy and satellite measurements. Root mean square differences (RMSD) of the magnitude of storm surge between model results and observations are 0.15 m. The model sea surface temperature showed a small decrease, consistent with observations, with RMSDs from 0.19 to 0.64 degrees C at buoy stations. The simulated surface current changes agree with buoy observations, with model-observation velocity difference ratios (VDR) of 0.75-0.88. It was found that, at Argentia (St. Lawrence), the peak storm surge in Placentia Bay was dominantly (moderately) associated with the inverse barometric effect, and the subsequent negative surge was mainly due to the wind effect at both stations. The sea surface cooling was associated with oceanic heat loss. In the momentum balance, the Coriolis, pressure gradient, and advection terms were all important during the storm, while the first two terms were predominant before and after the storm.
