Severe weather is any dangerous meteorological phenomenon with the potential to cause damage, serious social disruption, or loss of human life. [1][2][3] These vary depending on the latitude, altitude, topography, and atmospheric conditions. High winds, hail, excessive precipitation, and wildfires are forms and effects, as are thunderstorms ...
t. e. A storm surge, storm flood, tidal surge, or storm tide is a coastal flood or tsunami -like phenomenon of rising water commonly associated with low-pressure weather systems, such as cyclones. It is measured as the rise in water level above the normal tidal level, and does not include waves. [1]
Coastal areas are sometimes flooded by unusually high tides, such as spring tides, especially when compounded by high winds and storm surges. This was the cause of the North Sea flood of 1953 which flooded large swathes of the Netherlands and the East coast of England. When humans modify the coastal environment this can make coastal flooding worse.
Wind fetch. In oceanography wind fetch, also known as fetch length or simply fetch, is the length of water over which a given wind has blown without obstruction. [2][3] Fetch is used in geography and meteorology and its effects are usually associated with sea state and when it reaches shore it is the main factor that creates storm surge which ...
Wind shear is a microscale meteorological phenomenon occurring over a very small distance, but it can be associated with mesoscale or synoptic scale weather features such as squall lines and cold fronts. It is commonly observed near microbursts and downbursts caused by thunderstorms, fronts, areas of locally higher low-level winds referred to ...
Coastal erosion. Heavy marine erosion: cliff fall at Hunstanton in the east of England. Sea erosion at Valiyathura Kerala, India. Tunnel-like structures formed by erosion in Jinshitan Coastal National Geopark, Dalian, Liaoning Province, China. Coastal erosion is the loss or displacement of land, or the long-term removal of sediment and rocks ...
The wind stress is the component of this wind force that is parallel to the surface per unit area. Also, the wind stress can be described as the flux of horizontal momentum applied by the wind on the water surface. The wind stress causes a deformation of the water body whereby wind waves are generated. Also, the wind stress drives ocean ...
Derecho. A derecho (/ ˈdɛrətʃoʊ /, from Spanish: derecho [deˈɾetʃo], 'straight') [1] is a widespread, long-lived, straight-line wind storm that is associated with a fast-moving group of severe thunderstorms known as a mesoscale convective system. [2] Derechos cause hurricane-force winds, heavy rains, and flash floods.
