HYDROMETEOROLOGICAL HAZARD Flashcards
is the abnormal rise in seawater level during a storm, measured as the height of the water above the normal predicted astronomical tide.
It is caused primarily by a storm’s winds pushing water onshore.
the intensity, size, and speed of the storm; and the local bathymetry
STORM SURGE
Three basic ingredients are required for a thunderstorm to form: moisture, rising unstable air (air that keeps rising when given a nudge), and a lifting mechanism to provide the “nudge.”
THUNDERSTORM
Shape of the Coastline:
The shape of the coastline and the underwater topography play a role in amplifying or reducing the impact of storm surge. Narrow bays or estuaries can funnel water, amplifying the surge, while gently sloping coastlines may experience less surge.
Tides:
The timing of the storm’s arrival relative to the natural tidal cycle can significantly influence the height of the storm surge. If the storm coincides with high tide, the surge can be much more severe.
Storm Intensity:
The intensity and size of the storm also play a crucial role. Larger storms with stronger winds tend to produce higher storm surges.
