The objective of this research is to analyse temporal changes in historic rainfall variability across Scotland using
different measures of variability. The CUSUM and sequential Mann-Kendall test applied to records from 28 weather
stations with up to 80 years of daily precipitation data reveal the occurrence of abrupt changes in the rainfall trends.
Most weather stations show a turning point between 1978 and 1985, although some stations situated in Eastern
Scotland have more than one turning point. The temporal changes in rainfall variability across Scotland are presented
using a number of measures of variability.
