Isohyet

An isohyet is a line on a weather map that connects points receiving the same amount of rainfall over a specified period. Think of it as a contour line on a topographic map, but instead of elevation, it shows equal rainfall levels. These lines help meteorologists visualize how rainfall varies across an area, highlighting regions of heavy or light precipitation. By analyzing isohyets, weather patterns, drainage planning, and flood risks can be better understood and managed.
