Michigan modelling sends storm warning

The theoretical link between storms and climate change has been bolstered with a new mathematical model from the University of Michigan that shows atmospheric phenomena like water spouts, tornadoes, hurricanes and cyclones develop from warmer and moister air.

These are the very factors that will increase as climate change warms the Earth.

Atmospheric and planetary scientist Dr Nilton Renno told MJ that there are implications for maritime events, saying, 'Small increases in the sea surface temperatures of these areas would produce relatively large increases in storm intensity.'

Dr Renno and research scientist Natalia Andronova predict that for every 3.6°F that the Earth's surface temperature warms, the destructive force of an intense storm could rise by as much as 10%.

This has an obvious impact on shipping and coastal defences, where some routes will become more prone to sudden and violent atmospheric changes. In the UK, the Marine Climate Change Impacts Partnership (MCCIP) has already noted that marine air and sea surface temperatures have been rising at a similar rate to land air temperature, but with strong regional variations.
