Changes in daily and nightly day-to-day temperature variability during the twentieth century for two stations in Switzerland
| Résumé |
An analysis of day-to-day variability was performed on two
century-longs daily minimum and maximum temperature series from
Switzerland. Warmer temperatures during the 20(th) century have
been accompanied by a reduction in day-to-day variability,
particularly for minimum temperatures and for winter. There is a
significant negative correlation between day-to-day variability and
the skewness of the temperature distribution, particularly in winter
and for minimum temperatures. Lower variability is linked to a
reduced number of cold days and nights. Higher NAO index values
tend to be associated not only with warmer temperatures but also
with lower day-to-day variability. This paper confirms that the
temperature warming during the 20(th) century has happened mainly
through the loss of the coldest part of the series, not only in the
24-hour or yearly cycle, but also through the loss of the coldest
episodes in each month. |
