Hurricanes can create tornadoes primarily due to changes in surface friction and wind shear when their rain bands make landfall, increasing the potential for severe weather.
While tornadoes accompanying hurricanes are typically weak and short-lived, those spawned by Hurricane Milton were observed to be slightly more intense than usual, indicating a shift in conditions.
Meteorologists emphasize that interaction with land leads to an increase in surface friction, which can slow winds and create significant changes in wind speed and direction, vital for tornado formation.
Dr. Jana Houser explains that the process starts with a change in wind patterns caused by surface friction, creating spinning air that can be intensified by strong updrafts.
