What I do

My main research is focused on developing and improving hydroclimate forecasting systems at medium-range, sub-seasonal and seasonal time scale for maximizing societal benefits. It consists of applying numerous approaches on

Ensemble post-processing of numerical models
Statistical downscaling
Multi-Model Ensemble

Before joining UFZ, I have contributed in policy advice and analysis pertinent to water resources management in semi-arid regions in Southwest Asia to establish a national water observatory.

In UFZ, I am currently developing an operational near real-time hydroclimate forecasting system over Germany at sub-seasonal to seasonal (S2S) time scales. In addition, I am investigating the reliability of early warning of hydrological extremes, and heatwave forecasts and their compound effect.

Modular Observation Solution for Earth Systems (MOSES)

Novel observing systems will improve understanding of the complex interactions across scales and Earth compartments. My research is part of the MOSES project, a joint facility in the research field “Earth and Environment” proposed and implemented by the Helmholtz Centres.

Online forecast information out of my research will provide information for conducting new event-oriented observation campaigns and contributing to progress in Earth observation. Forecast information of weekly precipitation, maximum air-temperature and soil moisture over Germany contributed to MOSES by UFZ will be disseminated online via the HS2S weblink.

Aug 20, 2021

Open house days of the Swabian MOSES Campaign received large public interest. A research consortium of several Helmholtz centers, universities and the German Weather Service, investigates the cause and effects of hydro-meteorological extremes such as heavy thunderstorms, high precipitation and floods as well as heatwaves and droughts. The MOSES initiative is coordinated by the UFZ.

Start of the third phase of Collaborative Research Centre AquaDiva, investigating the links between surface and subsurface signals in the earth critical zone. Two projects are lead by researchers of CHS. They will investigate with modeling and observations how temporal and spatial variation of surface input and processes during subsurface transit drive the water flow and element transport to groundwater and rivers.

We are happy to announce the next release of mHM: v5.11.2 .

May 19, 2021

In October 2020 a new Helmholtz Young Investigator group ( link ) led by Jakob Zscheischler started in CHS. The group will work on compound weather and climate events with a particular focus on using novel ideas from explainable machine learning to identify compounding weather drivers of extreme impacts such as vegetation mortality, crop failure and floods. Recently the group was awarded a Helmholtz AI project called CausalFlood, in which compounding drivers of floods will be identified based on causal inference in collaboration with the group of Jakob Runge from DLR.
