Climatology of the NAO and North Atlantic hurricanes from 1950 to 2008: an analysis of physical and spatial comparisons
Tropical cyclones (TCs) are responsible for the destruction of millions of dollars in property and potentially the loss of hundreds of lives each year. Although essentially a stochastic meteorological phenomena, they owe their genesis, existence and fate to many natural modes of climate variability....

Tropical cyclones (TCs) are responsible for the destruction of millions of dollars in property and potentially the loss of hundreds of lives each year.
