What does it mean when the weather reports that there was 1” rainfall?
In: 3
It’s measured with a rain gauge which is a funnel or cyclindrical shaped container placed outside. When it rains it collects some rain water and measures how much water was collected. So if rains for 2 hours and fills up with 16mm of water at the end then it meant the average rate of rain was 8mm/hour which is considered heavy rain
