What is the primary purpose of IMD normals?
Think of the duration used in climatology.
How long is the rainfall data period for IMD normals?
It's a common duration used in climatology.
What do IMD normals provide?
Focus on the specific timeframe mentioned.
True or False: The Normal Ratio Method uses current rainfall to estimate missing data without considering historical records.
Think about how historical trends influence current estimations.
Given the normals of three nearby stations: Station A (200 mm), Station B (180 mm), Station C (160 mm) and observed rainfall of 190 mm at Station D, estimate the missing rainfall at Station D using the Normal Ratio Method.
Focus on how ratios are derived from the normals.
Evaluate a scenario where normals of a station have changed significantly over the years. How would you approach estimating missing data under this condition?
Think about how historical consistency impacts current data.
