### Instruction: There are two definitions currently used for subtropical cyclones depending on which two geographic locations?
### Input: There are two definitions currently used for subtropical cyclones depending on their location. Across the north Atlantic and southwest Indian Ocean, they require some central convection fairly near the center surrounding a warming core existing in the mid-levels of the troposphere. Across the eastern half of the northern Pacific however, they require a mid-tropospheric cyclone to be cut off from the main belt of the westerlies and with only a weak surface circulation. Subtropical cyclones have wider wind fields with the maximum sustained winds located further from the center than typical tropical cyclones, and have no weather fronts linked into their center.
### Response: Subtropical cyclones are defined differently between the north Atlantic/southwest Indian Ocean area and the northern Pacific.
