Suppose you have three rain gauge stations with the following data: Station A: 100 mm, Station B: 150 mm, Station C: 200 mm. If their corresponding polygon areas are 10 km², 20 km², and 30 km², respectively, calculate the average areal rainfall.
💡 Hint: Use weighted averages based on the area.
Consider a scenario where two rain gauges are located at different elevations (100 m and 200 m) but within close distance. Discuss how you would apply the Thiessen Polygon Method and what additional factors you might need to consider.
💡 Hint: How does elevation impact rainfall data?
