Subtropical storm is a type of weather system that has characteristics of both tropical and extratropical cyclones. They typically form in the subtropics, between the tropics and the mid-latitudes, and are most common in the western North Pacific Ocean and the South Atlantic Ocean.

Subtropical storms have wind speeds of less than 74 miles per hour (119 kilometers per hour), and they do not have the well-defined eye that is characteristic of tropical cyclones. However, they do have a warm core and a low-pressure center, and they can produce heavy rainfall and strong winds.

Subtropical storms are different from tropical cyclones in several ways. First, they are typically larger in size than tropical cyclones. Second, they have a less symmetric wind field, with stronger winds on one side of the storm than the other. Third, subtropical storms typically move more slowly than tropical cyclones.

Subtropical storms are also different from extratropical cyclones. Extratropical cyclones are typically larger in size than subtropical storms, and they have a more complex wind field. They also typically move faster than subtropical storms.

Subtropical storms can be dangerous, and they can cause significant damage. However, they are not as intense as tropical cyclones, and they are not as common.
