Global climatology of explosive cyclones

Feb 11, 2013

Explosive cyclones, which have rapidly intensifying winds and heavy rain, can seriously threaten life and property.

These "meteorological bombs" are difficult to forecast, in part because scientists need a better understanding of the physical mechanisms by which they form. In particular, the large-scale circulation conditions that may contribute to explosive cyclone formation are not well understood.

Black and Pezza analyzed broad-environment energetics in creating a global climatology of explosive cyclones.

They identify global hotspots for explosive cyclones and find that explosive cyclones in different geographical locations share a similar characteristic energy-conversion signature that can easily be identified in .

The study could help improve storm track prediction.
