Are hurricanes/cyclones/typhoons in the Pacific Ocean usually larger than in Atlantic Ocean?
Typhoons in the western North Pacific ocean can be larger than hurricanes, because the great expanse of ocean water in the Pacific gives them more time and space to develop. Typhoon Tip in 1979 produced gale winds or higher over a diameter of 1400 miles. This is to my knowledge the largest western Pacific typhoon of record (it was also one of the most intense --- near-all-time-record maximum sustained winds of 190 mph, minimum barometric pressure an all-time record low of 25.6 inches of mercury). Typhoon Tip's 1400-mile diameter of gale-force or higher winds is almost double that of the largest hurricanes of record.
