The average latitude at which tropical cyclones attain their maximum intensity has undergone a significant shift towards the poles over the last three decades, according to new research led by James Kossin at University of Wisconsin.
The research, which studied historical storm data, discovered that the rate per decade at which tropical cyclones have been moving towards both the North and South poles is between 53 and 62 kilometres.
When observed in conjunction, the trends in the north and south depict an average global migration away from the tropics at approximately one degree of latitude every ten years.
