What contributes the storm surge?
"Storm surge" is the above-normal water level caused by tropical storms, especially by the high winds. The storm surge can be higher or lower than otherwise might be the case depending on the tides; a storm surge at high tides can be far more destructive than the storm at low tides.
Are high wind called storm surge?
No, high winds and storm surge are two different weather phenomena. High winds refer to the movement of air at high speeds, while storm surge is an abnormal rise in sea level during a storm that can cause flooding in coastal areas. Storm surge is typically caused by the strong winds and low pressure of a storm pushing water towards the shore.
How will high tide and a full moon affect storm surge with Hurricane Sandy?
When the storm surge of a hurricane comes in at high tide the affect is worse, as the height of the high tide is added to the storm surge to produce a storm tide. The high tide is highest during the full and new moon phases.
What causes a hurricane's storm surge other than a combination of high winds?
Low pressure also contributes to the storm surge.
What is storm tide?
Storm tide occurs when the storm surge of a hurricane comes in on top of high tide. The heights of the storm surge and high tide are added together, resulting in worse flooding than if they same storm had struck at low tide.
