What is a hyetograph? A hyetograph is a graphical representation of rainfall intensity over time. It helps meteorologists, hydrologists, and environmental scientists understand precipitation patterns and predict flooding or droughts. By plotting rainfall data on a graph, a hyetograph shows how much rain falls during specific time intervals, making it easier to analyze weather events. This tool is crucial for designing stormwater management systems, agricultural planning, and studying climate change impacts. Whether you're a student, a weather enthusiast, or a professional in the field, understanding hyetographs can provide valuable insights into our planet's water cycle and weather patterns.
