It is remarked that typhoons often arrive in quick succession followed by intervals without typhoons, but during the height of the typhoon-season there is generally a typhoon to be found some- where at any time. The following table exhibits the number of typhoons that occurred during the past three years within squares of 2° extent in longitude and latitude :-
