FAQ
The 24-hour hyetograph displays hourly precipitation volumes recorded over the past 24 hours in a chronological bar sequence.
Key takeaways for reading this chart: 1. [Persistent Inflow]: Steady, uniform bars across multiple consecutive hours indicate continuous frontal rainfall, monsoon troughs, or typhoon outer rainbands. 2. [Flash Downpours]: A solitary spike towering over 1 to 2 hours reflects sudden convective thunderstorms, signaling immediate localized drainage strain. 3. [Rainfall Momentum]: Comparing the recent bars on the far right shows whether rainfall is easing off (shortening bars) or escalating (growing bars).
