Klaus WolterResearch Scientist
My main research interests lie in empirical climate research, in particular the application of statistical methods to climate problems, such as the impact of ENSO (El Niño/Southern Oscillation) on world-wide climate. I have developed and refined a “Multivariate ENSO Index” (MEI) based on tropical Pacific ship-based observations of sea level pressure, near-surface wind fields, sea – and air surface temperatures, as well as total cloudiness. The MEI is more robust than conventional indices in monitoring the ENSO phenomenon. Visit the 'Related Link' below for monthly updates and discussions of the MEI as well as relevant publications.
In the last decade, I have been able to devote more attention to the analysis and prediction of U.S. climate, being involved in the Western Water Assessment (WWA) project at CU and, more recently NIDIS (National Integrated Drought Information System). In this context, I have developed statistical tools that allow me to make seasonal climate predictions, such as documented at the Colorado Water Conservation Board.
I have been involved in recent regional and national assessments of extreme climate events as well as overall climate change, and was a co-author of a 2008 report to the Colorado Governor.
I am also part of the 'Climate Scene Investigation' team here at the NOAA/ESRL Physical Sciences Division that attempts to sort out how much if any of recent climate and weather extremes can be attributed to anthropogenic forcing (such as the March 2012 ‘heat wave’, Dole et al., 2014).
