About Ida Bülow Gregersen and her project:

I’m an environmental engineer from DTU and initiated my PhD study entitled “Statistical Modeling of Climatic Extremes in Relation to the Hydrological Cycle” in May 2010. During my study, to become an engineer, I have had several courses in statistics and hydrology and both my bachelor and master thesis, entitled “Development in Extreme Precipitation over Europe due to Climate Change” and “Statistical Trend in Observed Extreme Rainfall”, respectively, have been within the area of extreme rainfall.

The objective of my PhD is to develop and apply non‐stationary time series models of extremes with the aim of identifying changes in key hydrologic design variables and thus the timing and severity of changes in risk to urban infrastructure. The developed models must both account for short and long term natural and inherent variation together with the spatio‐temporal correlation structures for the extreme rainfall characteristic. The planned analysis includes both historical time series from a Danish high resolution rain gauge network and transient Regional Climate Model (RCM) simulations from the ENSEMBLES project, aiming for an identification of the differences/similarities between the RCM output and the observations with respect to the modeled parameters.
