Question 1.
What is the minimum number of rain gauges recommended for flat regions?
Show hintHide hint
Think about how many square kilometers a flat region covers.
Question 2.
What does WMO stand for?
Show hintHide hint
It's an international organization focused on weather science.
3Question 3.
What is the density of rain gauges recommended for mountainous regions?
- 1 per 250 km²
- 1 per 625 km²
- 1 per 100 km²
Show hintHide hint
Recall the specific recommendations set forth by WMO.
4Question 4.
True or False: Urban areas need less density of rain gauges than flat regions.
- True
- False
Show hintHide hint
Remember the density requirements stated in the guidelines.
Question 5.
A region has been urbanized significantly, and data shows that the rainfall variability is now 0.5. If planners originally wanted a density of 1 gauge per 500 km², how should they adjust their gauge placement?
Show hintHide hint
Make sure to recalculate the density based on the new coefficient of variation.
Question 6.
In a flat region of 1000 km², how many rain gauges would be necessary according to WMO guidelines? How does that change if you consider urbanization?
Show hintHide hint
Calculate the number of gauges based on the area and the guideline provided.
