Harold F. Dvorak

Harold F. Dvorak was a meteorologist who developed a system to estimate the strength and potential danger of tropical cyclones, like hurricanes. His method involves analyzing satellite images to identify specific cloud patterns, such as the shape and structure of clouds around the storm's center. By recognizing these features, meteorologists can quickly determine if a hurricane is strengthening or weakening, improving early warnings and preparedness. Dvorak's approach revolutionized how storms are assessed from space, making forecasting faster and more accurate, ultimately helping communities better prepare for severe weather events.
