Looking for good test cases for RR_24 redistribution algorithm

Plan:

1. Review 24hr precipiation charts from http://senorge.no/
2. Classify each day if it is
   1. No rainfall
   2. Convective Rainfall
   3. Frontal/uniform precipitation
3. If possible do this based on regions

Initial test regions:

Later will iterate to better region split based on learning … where is that AI neural net when you need it ?

Suggestion: Precipitation regions is used for rainfall and for runoff. Data for these regions can be used to make trends in accumulated precipitation, see met.no - the trend diagram here is made for geographical regions, but the same has been done for the precipitation regions.

Precipitation regions:

The attached file identifies each station with its particular precipitation region (number in the NR_NO nedbør region column) as illustrated by the following excerpt:
