Influence of different daily mean formulas on monthly and annual averages of temperature

Theoretical and Applied Climatology Aims and scope Submit manuscript

Summary

For eight Swiss stations with daily records available since the turn of the century, daily mean temperatures are computed in two ways. The long term behaviour of the resulting monthly and annual averages is compared for the two different daily mean formulas. Qualitatively both types of daily means show similar interannual variations. There are however changes in the quantitative description like a linear trend analysis. The daily mean obtained from extremum readings seems to be more stable with respect to station dependent influences. The analysis of monthly mean values shows that most of the observed warming in this century occurred in autumn.
