Local wind patterns and global wind patterns are main causes for cyclonic storms.
<u>Explanation</u>:
Tornadoes are formed over the land, while hurricanes are formed on the water. Hurricanes are formed as of a storm in a tropical area or warm area, on the other hand hurricanes are formed due to different situations in various places. When large masses of air of different temperature and densities meet together, cyclone storms are caused. As the lower density air mass rises and the cooler descents, what is formed is called a weather front, and the coriolis effect makes the front to start spinning and form a funnel. The biggest fuel system is water vapor from the oceans in a tropical storm. The water releases heat and surrounds the air as the water vapor rises and condenses, causing a low pressure, hence the cooler air masses moves to the region with low pressure as the warm air goes up. The spiral begins and a tropical storm is formed. This is how local and global wind patterns affects the formation of tornadoes and hurricanes.
