A mathematician has developed a piracy prediction model based on wind, waves, currents, as well as on the ground intelligence that could help predict the probability of a pirate attack on a given day; the system would function like a tornado warning system using weather data to project high risk areas on a map; the map could be further refined by adding in real time shipping traffic to indicate which ships are most likely to be attacked; piracy has grown worse in the last year, despite stepped up naval patrols; 80 percent of the world’s cargo still travels by sea
