<human>:  What's the difference between a hurricane and a typhoon?
<bot>: The primary difference between a hurricane and a typhoon is that hurricanes form in the Atlantic and eastern Pacific Oceans and typhoons form in the western Pacific and Indian Oceans. In addition, hurricanes usually have a lower wind speed than typhoons. Hurricanes are also characterized by a large circular wind pattern, whereas typhoons have a spiral wind pattern. Finally, the name for a storm is determined by the region it occurs in; hurricanes occur in the Atlantic and eastern Pacific and are called hurricanes, while storms occurring in the western Pacific and Indian Oceans are called typhoons.
