Climate Change Modelling and Application (CCMA)

Research programme Leader: Dr Pushp Raj Tiwari

The overarching goal of our research group is to shed light on mechanisms and physical processes controlling climate change at different spatial and temporal scales. We focus on aerosol-cloud–climate interaction and work towards reducing the current uncertainty related with them. We aim at comprehensively investigating the relationships with other anthropogenic forcing agents (eg greenhouse gases, land-use changes, etc.) and with the underlying natural climate variability. We are interested in conducting studies in a multidisciplinary framework, in which the interactions between climate and other disciplines (eg air quality and health, water and energy management, agriculture) are also investigated. To achieve these goals, we use a variety of tools, from observations to a range of state-of-the-art climate models of various complexities, data driven approaches (Machine learning) supported by a solid theoretical analysis.

As part of our research, we have an extensive collaboration network including UK Met Office, ECMWF, University of Reading, University of Leeds, University of Cambridge,  Rothamsted Research Centre, Stockholm University, Finnish Meteorological Institute, IRI Columbia University, NCAR, CIRES/University of Colorado NOAA, ICTP Italy, IIT Delhi, IIT Bhubaneswar and NCMRWF.

Our current projects include:

  • Regional Climate change over South Asia and Africa
  • Weather, climate and air quality extremes over South Asia and Africa
  • Climate change and its impact on food, energy and water security
