Abstract:

Mathematical modelling of hydrometeorological extremes and their impacts was discussed.An introduction to the notion of modelling is proposed. Annual extremes in temperaturerecords were examined, also on the basis of qualitative indices, when quantitative data are notavailable due to cost restrictions. Trends in long time series of records were studied. Concepts asregards projections of risk of extreme events (such as floods) are also discussed; including synthesisof projection models for a range of climate impacts. The facets of uncertainty are also dealtwith. A conceptualization of the risk in the load-resistance framework is proposed.

Abstract:

The climate change projections for Poland are consistent in foreseeing overall temperatureincrease in the coming decades. Precipitation is projected to decrease in summer (thoughthis finding is not robust, being model-dependent) and to increase in winter. It is expected thatthe occurrence of climate extremes over Poland may change in the future, warmer climate.In this study, daily temperature and precipitation data from the Hadley Centre HadRM3-PRECIS regional model simulations (for the SRES A2 scenario in three model experiments)in Poland were used to study temperature and precipitation extremes defined according to thespecification made in the Integrated Project entitled “Extreme meteorological and hydrologicalevents”. Climate extremes in the control period, 1961–1990, were compared with those in theprojection period, 2071–2100.
