3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Astronomical wave
Tides caused by the tidal forces of the moon, sun and other celestial bodies.
[GB/T 15920-2010, definition 2.5.20]
3.2
Storm surge
Local sea surface oscillations caused by strong winds and sudden pressure changes associated with storm transits such as tropical cyclones, temperate weather systems, and sea squall lines
Or non-periodic abnormal increase (decrease) phenomenon.
Note. The phenomenon of local sea surface oscillation or non-periodic anomalous rise during storm surge is called storm surge, which is referred to as water augmentation.
The reduction phenomenon is called storm water reduction, or water reduction for short.
[GB/T 19721.1-2017, definition 3.1]
3.3
Maximum storm surge peaksurge
The maximum value of hourly water increase during a storm surge is also called maximum storm water increase.
[GB/T 19721.1-2017, definition 3.2]
3.4
Storm of disaster disasterofstormsurge
Disasters caused by flooding along the coast caused by the superimposition of storm surge, astronomical tide and ocean waves are collectively referred to as.
