An empirical method for estimating probability density functions of gridded daily minimum and maximum temperature
The presented work focuses on the investigation of gridded daily minimum (<i>TN</i>) and maximum (<i>TX</i>) temperature probability density functions (PDFs) with the intent of both characterising a region and detecting extreme values. The empirical PDFs estimation procedure...

The presented work focuses on the investigation of gridded daily
minimum (<i>TN</i>) and maximum (<i>TX</i>) temperature probability density functions
(PDFs) with the intent of both characterising a region and detecting extreme
values. The empirical PDFs estimation procedure has been realised using the
most recent years of gridded temperature analysis fields available at ARPA
Lombardia, in Northern Italy. The spatial interpolation is based on an
implementation of Optimal Interpolation using observations from a dense
surface network of automated weather stations. An effort has been made to
identify both the time period and the spatial areas with a stable data density
otherwise the elaboration could be influenced by the unsettled station
distribution. The PDF used in this study is based on the Gaussian
distribution, nevertheless it is designed to have an asymmetrical (skewed)
shape in order to enable distinction between warming and cooling
events. Once properly defined the occurrence of extreme events, it is possible
to straightforwardly deliver to the users the information on a local-scale in
a concise way, such as: <i>TX</i> extremely cold/hot or <i>TN</i> extremely cold/hot. |
