South Asian precipitation, a seamless assessment

The full title of this project is South Asian precipitation, a seamless assessment (SAPRISE).

Background to the project

The Indian summer monsoon provides about 80% of annual rainfall to around a billion people in South Asia and variations in its timing, intensity and duration have a dramatic impact on society. The weather and climate in the South Asian region is influenced the Indian and remote ocean basins via teleconnections to phenomena such as El Niño. Aerosol particles are also key component of the South Asian atmosphere due to the prevalence of cooking fires over the Indo-Gangetic Plain and dust blown from local and remote deserts. Key tools to understand variations in S. Asian precipitation are new climate models that simulate the interactions between the different teleconnections and aerosols, and new observations, especially those from satellites.

Objectives

The main aims of the project are to advance our understanding of the physical processes that control the Indian monsoon and its variations on time scales from seasons to centuries. We will utilize the latest numerical model simulations and hindcasts, particularly those from CMIP5, and integrations with the latest version of the Met Office Hadley Centre model, HadGEM3. A seamless approach will link seasonal, decadal and centennial variability and change via understanding of physical processes.
