prettygoodwordhyetograph (hai-ET-uh-graf, HAI-i-tuh-graf) - n., a graphical representation of rainfall over time.
Can be a chart or a map, and the timescale can be a specific storm or over the year. Useful for measuring storm intensity, depending on how fast that rain is coming down. Contrast with a hydrograph, which shows the rate of water flow out of a system, while a hyetograph shows flow into it. Coined from scientific vocabulary hyeto- (from Ancient Greek huetós, rain) + -graph (from Ancient Greek graphḗ, writing/drawing).
