Final answer:
In the Northern Hemisphere, low-pressure systems like hurricanes rotate in a counterclockwise direction, and high-pressure systems rotate in a clockwise direction, all due to the Coriolis force.
Step-by-step explanation:
In the Northern Hemisphere, swirling wind patterns around low-pressure zones, such as hurricanes, rotate in a counterclockwise direction due to the Coriolis force. This deflection is caused by the Earth's rotation, which affects large-scale motion such as wind patterns. Conversely, wind patterns around high-pressure zones move in a clockwise direction. However, these high-pressure zone patterns are less visible from space since they are associated with sinking air and thus, clearer skies.
To answer the student's question directly:
- How many swirling wind patterns travel in a clockwise direction? High-pressure systems.
- How many swirling wind patterns travel in a counterclockwise direction? Low-pressure systems such as tropical cyclones and hurricanes.
