STORMS


Storms have the potential to harm lives and property via storm surge, heavy rain or snow causing flooding or road impassibility, lightning, wildfires, and vertical and horizontal wind shear. Systems with significant rainfall and duration help alleviate drought in places they move through. Heavy snowfall can allow special recreational activities to take place which would not be possible otherwise, such as skiing and snowmobiling.


Storms are created when a centre of low pressure develops with the system of high pressure surrounding it. This combination of opposing forces can create winds and result in the formation of storm clouds such as cumulonimbus. Small localized areas of low pressure can form from hot air rising off hot ground, resulting in smaller disturbances such as dust devils and whirlwinds.


Storms can cause huge damage, not only to property, infrastructure, but also to sea beds.

Scientists studied the return of life to the Lyme Bay Marine Protected Area (MPA), damaged in 2013 and 2014.

The zone, which runs from near Exmouth in Devon along the Dorset coast, was monitored by underwater cameras.

They said "extreme" storms are increasing in strengthen and frequency because of climate change.

 

The storms which struck the south coast of England in the winter of 2013 and 2014 were the most powerful since 1948.
