7.3. Density of Rain Gauge Network

Try these first

1. 1.

   What is the minimum number of rain gauges recommended in flat regions?

   Hint

   Think about large flat lands.

2. 2.

   Which organization provides density guidelines for rain gauge networks?

   Hint

   Think of the world weather organization.

3. 3.

   What is the minimum recommended gauge density for flat regions according to WMO?

   • 1 per 625 km²
   • 1 per 250 km²
   • 1 per 100 km²

   Hint

   Recall the flatland considerations.

4. 4.

   Is it true that the IMD has more stringent requirements than the WMO for rain gauge density?

   • True
   • False

   Hint

   Think about how regional factors influence guidelines.

5. 5.

   A mountainous area of 1500 km² needs to be surveyed. According to WMO guidelines, how many rain gauges are necessary?

   Hint

   Use the formula where you divide total area by coverage area per gauge.

6. 6.

   Evaluate the potential impacts of implementing the WMO density guidelines in an urban coastal region that's experiencing climate change.

   Hint

   Consider how changing weather patterns affect rainfall.
