用海岸和星载雷达观测的风暴潮：不列颠哥伦比亚省的个例研究
Storm Surges as Seen by Coastal and Spaceborne Radars: Case Studies in British Columbia
摘要：
大气突变引起的短期海平面波动对沿海地区可能是危险的现象。我们报告了2020年发生在加拿大不列颠哥伦比亚省海岸的两次这样的风暴潮。地面和空间传感器的罕见一致性使得有可能用各种仪器观测这些事件：（1）沿海海洋学雷达;（2）哨兵-1 B号卫星上的合成孔径雷达;（3）海岸验潮仪网络。根据这些案例研究，我们展示了如何卫星雷达数据可以用来补充观测和解释的地面测量的背景下，"海啸般“的海平面振荡。
英文摘要：
Short-term sea level fluctuations prompted by abrupt atmospheric changes can be hazardous phenomena for coastal regions. We report on two such recent storm surges that occurred in 2020 on the shores of British Columbia, Canada. A rare concordance of ground-based and spaceborne sensors made it possible to observe these events with a variety of instruments : (1) a coastal oceanographic radar; (2) the synthetic aperture radar onboard satellite Sentinel-1B; and (3) a network of shoreside tide gauges. In the light of these case studies we show how satellite-based radar data can be used to complement the observation and interpretation of ground-based measurements in the context of ``tsunami-like'' sea level oscillations.
