Summary of the Video
• Hurricane Formation and Season: Hurricanes, also known as tropical cyclones, form in the Northern Hemisphere near the equator, primarily off the coast of West Africa. The official hurricane season runs from June 1st to November 30th because ocean surface temperatures must reach at least 79°F, along with high-pressure systems and low wind shear, conditions frequently met during these months. • Hurricane Fuel and Mechanics: Hurricanes function like giant engines fueled by warm, moist air rising from warm ocean waters. This rising air creates a low-pressure system, drawing in surrounding high-pressure air, which then warms, moistens, and rises, forming clouds and wind. The Coriolis effect, due to Earth's rotation, causes the hurricane to spin counter-clockwise in the Northern Hemisphere. • Hurricane Strength and Peak Season: Hurricane strength is measured by wind speed and barometric pressure, with Category 5 hurricanes exceeding 157 mph. September typically sees the most hurricanes due to peak warm ocean surface temperatures during that month.
