Record models for temperature and rainfall

Event details

A record is an entry in a time series that is greater or smaller than all previous entries. The public perception of weather extremes is particularly sensitive to record-breaking events, which often receive extensive media coverage. As a consequence, a number of recent studies have been aimed at detecting and quantifying the
effects of a warming climate on the frequency of temperature records.

In comparison, the effects of climatic trends on precipitation records are more complex and have generally received less attention. After a brief introduction to the classic theory of records, the talk will describe two simple models describing the occurrence statistics of record-breaking daily temperatures and precipitation amounts, respectively. In the latter case our main finding is that the presence of dry days of zero precipitation induces nontrivial correlations between record-breaking events that can be detected in empirical data.

About Condensed Matter lunchtime seminars

This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
