Abstract
In the present paper, modelling extreme temperature to assess risk of
global warming in Ireland is addressed. The approach used is a combination of
peak-over-threshold (POT) – generalised Pareto distribution (GPD) in which
the parameter of distribution is allowed to vary with a dominant feature of
climate at the location. The dominant climatic feature at a location is
approximated by climatic variables derived from the National Centre for
Environmental Prediction (NCEP) reanalysis data. Data from six stations were
used to develop seasonal models for winter, spring, summer and autumn.
Future changes in extreme temperature values are generated by using climate
variables derived from (HadCM3) GCM for the A2 emissions scenario. The
software extRemes was used to develop the models as it serves the proposed
modelling approach. Results indicate that significant changes in extreme
temperature events are projected to occur in Ireland over the course of the
present century. These include hotter summers and mild winters.
