Probability density of hurricanes (times 1000) computed from storm data in the Asian Pacific basin for the period 1960–2007 shown as a function of the variable z defined in terms of the sea surface temperature and the latitude according to with C, and with Southern Hemisphere data artificially displayed as having negative -values. represents the probability of having a storm per month for a given -interval. The size of the horizontal and vertical error bars is discussed in the text. The data is consistent with the power law curve.
