• Tropical cyclones have - spiral rain bands, eye wall, and eye
• The spiral rain bands surround the eye
• Eye - are with the lowest air pressure and its wind speed is also low. Served as a reference point in plotting the typhoons location.
• Eye wall - surrounds the eye, where the severe weather occurs. innermost ring of convection near the center of the typhoon, packing the fiercest rains and most intense winds.
• Spiral rain bands - found outside the eye wall, long bands of clouds and thunderstorms that spiral out of the eye wall. "also referred to as "buntot ng bagyo"
