Storm surge is the deadliest part of a hurricane. Discover what causes this effect, and which regions are most at risk.
Storm surge is produced by water being pushed toward the shore by the force of the winds moving cyclonically around the storm. The impact on surge of the low pressure associated with intense storms is minimal in comparison to the water being forced toward the shore by the wind. Wind and Pressure Components of Hurricane Storm Surge
The maximum potential storm surge for a particular location depends on a number of different factors. Storm surge is a very complex phenomenon because it is sensitive to the slightest changes in storm intensity, forward speed, size (radius of maximum winds-RMW), angle of approach to the coast, central pressure (minimal contribution in comparison to the wind), and the shape and characteristics of coastal features such as bays and estuaries.
It’s hard to believe it’s been five years since I made my first Vorticity film. The one goal I had that year was to get a tornado on time-lapse for the first time ever. That happened and it’s been a wild, incredible ride since. The storms I’ve witnessed have been moving, stunning and a few of them, legendary (at least to us chasers!).
The 2021 season was no different. The number of supercells we saw and the level of structure was absolutely amazing. From Sudan, Texas to Malta, Montana…the chases were a blast and the time-lapses I caught were just fantastic fun. So many supercells, so many chases…I think I counted about 27 days we chased from late April to late June. Definitely one of the more active springs in recent years. It was good enough that I felt I could put out another worthy entry in the Vorticity series, so hopefully you agree!
Climate change has made extreme rainfall events of the kind that sent lethal torrents of waterhurtling through parts of Germany and Belgium last month at least 20% more likely to happen in the region, according to an international study published Tuesday (August 24).
Clean drinking water is vital – but for many people, accessing it is difficult and expensive. A pastor in an Indonesian village encourages people to make use of a dependable water supply that comes free of charge: rainwater.
The state is increasing funding and preventative measures, but it may not be enough. A year after one of the worst wildfire seasons in California’s history, the state is taking more preventive measures to reduce wildfire risks. But experts worry it still doesn’t have the firefighting and land management resources to adequately fight worsening blazes. Photo: Noah Berger/AP
00:00 The death toll from Germany’s devastating flood disaster has risen to more than 160, as emergency workers continue to search for dozens of people still unaccounted for. German authorities insist their flood warnings worked, even though there was massive loss of life. Some experts say Germany’s flood warning system failed and has led to such widespread devastation. They say authorities knew what was coming, but failed to prepare.
