Question 1.
What does the Arithmetic Mean Method entail?
Show hintHide hint
Think about how you calculate an average.
Question 2.
When do we use the Normal Ratio Method?
Show hintHide hint
Consider the percentage difference.
3Question 3.
What does the Arithmetic Mean Method primarily use to estimate missing rainfall data?
- Surrounding station values
- Weather patterns
- Historical data
Show hintHide hint
Think about how averages work.
4Question 4.
Does the Normal Ratio Method rely on the uniformity of rainfall?
- True
- False
Show hintHide hint
Consider what 'normal' means.
Question 5.
A station recorded 120 mm while two nearby stations recorded 100 mm and 130 mm. Calculate the missing rainfall using the Arithmetic Mean Method.
Show hintHide hint
Add the values and divide by the total number of stations.
Question 6.
You have stations A, B, C reporting 50 mm, 100 mm, and 150 mm respectively. How would you estimate the missing data using the Inverse Distance Method assuming A is 1 km away, B is 3 km away, and C is 5 km away?
Show hintHide hint
Ensure to calculate contributions based on inverse distance.
