What would happen if such an ETC ripped through London?

Transcript of keynote speech by Donald Burfitt-Dons continued

All intense cyclones are accompanied by heavy rainfall and flooding and we are fortunate today to have with us Tim Reeder from Thames 2100 Project to explain our first line of defence for this, the largest cause of deaths.

Flying debris is also a major cause of casualties and we would see tiles and other objects sailing through the air at lethal speeds, Windows are normally sheeted over in areas which are accustomed to tropical cyclones. In our case injuries from shattering glass windows are likely to be severe.

Infrastructure damage is hard to assess because experience has shown that it is highest with a first event and lowers as the population adjusts its buildings and habits to the new conditions, but we would expect there to be severe collateral damage to occur in a first event.

On the same rationale we expect many rollovers from high sided vehicles in superwinds. Continued Donald Burfitt-Dons explains how superwinds form

the planet's way of recycling heat energy/ the first Brazilian hurricane/cyclones outside the tropics/how the GWA monitors hurricane activity/the rising tropopause/ETC activity since the 50s/l ETC activity since 1990/ the effect of an ETC on London /how superwinds form/ the impact of ETCs on aircraft/data from 21 recent storms/ UK as a breeding ground for tornadoes/ the impact on the insurance industry/ future implications /threat of ETCs to Europe and UK
