What causes hurricanes?
Synopsis
Winds in hurricanes can exceed 200 miles per hour, causing extreme rainfall and devastating storm surges when they make landfall.
Synopsis
Residents along the Florida coast prepare for the arrival of a hurricane, recalling past disasters and the devastation these storms can bring. Hurricanes, known for winds over 200 miles per hour, form from tropical waves that travel across the Atlantic. Conditions such as sea surface temperatures of at least 26.5 degrees Celsius and converging winds are crucial for their development. The documentary features insights from Oliver Morton, a senior editor at The Economist, who discusses the connection between hurricanes and climate change.
