Different terms are used for a storm depending on where it forms. In the Atlantic, tropical cyclones are called hurricanes, which are most likely to occur after surface temperatures peak and large amounts of moisture are already in the atmosphere. That season lasts from June to November, with the most perilous period from mid-August to mid-October.

Tropical cyclones in the northwestern Pacific, called typhoons, can form year-round because of warmer waters, but they most commonly occur from May to October.

And global warming has increased the amount of energy absorbed by oceans, which scientists believe has resulted in stronger storms.
