What does a mean annual precipitation map fail to show us?

Answer 1

The map fails to show us whether the rain falls in a fine drizzle over a l ong period of time or if it comes in sudden, quick thunderstorms.

In case that doesn't make sense, here's an example:If the mean annual precipitationmap for Coeur d'Alaine, Idaho, records 150 inches that year, then we are not sure if it rained 150 inches in January and February thunderstorms or if it lightly drizzled for eight months.

I hope this makes sense!

Answer 2

A mean annual precipitation map fails to show us the variability and distribution of precipitation throughout the year, as well as extreme weather events like storms or droughts. It also doesn't provide information on the intensity or duration of individual precipitation events.
