Abstract : Climatological records show that the number of tropical cyclones originated in the individual formation areas varies appreciably from year to year. These fluctuations do not appear to be completely random and there are periods as long as ten years when the average activity in given areas may be significantly above or below the long term average. Although these fluctuations appear as rather prominent features on the longer records, attempts to establish recurrent patterns were not very rewarding. (Author)
