Open exercise |

The attached file contains long term mean precipitation in autumn (September, October and November).

- Calculate autocorrelogram from the total autumn precipitation amount depicting spatial relationship in 10 km distance zones up to distance 500 km and add the autocorrelogramm to the answer.
- At which distances is the autocorrelation statistically significant (p < 0.01)?
- Add the correlogram and some thoughts how to climatically interpret the relationship.

The calculator of spatial data offers convenient ways to calculate spatial autocorrelation and to graph it (see Autocorrelation). Set parameters, press Calculate and see the results.
