A region has five rain gauges measuring rainfall of 50mm, 70mm, 90mm, 30mm, and 110mm respectively. If the gauges have equal area influence, what is the average precipitation using the Thiessen Polygon Method?
💡 Hint: How do you calculate the average of a series of numbers?
Given a rain gauge influenced polygon area of 400 km², how much weight would a rainfall measurement of 80mm contribute to the total mean precipitation calculation if there is another gauge with 200 km² influencing its measurement of 100mm?
💡 Hint: Consider how to balance weighted contributions based on area.
