一系列的年度和季节性降水量从32个站，分布在整个意大利领土，分为两组气候均匀，进行了研究，为1833年至1996年期间。检查系列的同质性，并根据Sneyers（1990）采用Mann Kendall检验及其逐步应用进行时间序列分析。结果表明，不同的季节和地区有相当大的不同趋势。意大利全境每年都呈现下降趋势，但只有中南部地区的下降趋势具有统计学意义。在季节性基础上，下降趋势仅在中南部的春季和北部的秋季显着。
Series of annual and seasonal precipitation from 32 stations, distributed over all Italian territory and divided in two groups climatically homogeneous, were studied for the period 1833–1996. The series were checked for homogeneity and the time series analysis was performed with the Mann Kendall test and its progressive application according to Sneyers (1990). The results show considerably different trends for different seasons and zones. On a yearly basis a decreasing trend is present over all Italy, but it is statistically significant only in the Central-South. On a seasonal basis a decreasing trend is significant only for spring in Central-South, and for autumn in the North.
