In this thesis, we investigated modes of intraseasonal variability (ISV) observed in the Indian monsoon rainfall and how these modes modulate rainfall over India. We identified a decreasing trend in the intensity of ...

Arctic geoengineering wherein sunlight absorption is reduced only in the Arctic has been suggested as a remedial measure to counteract the on-going rapid climate change in the Arctic. Several modelling studies have shown ...

Using a 50-year (1951-2000) gridded (1-degree) daily rainfall data set over the Indian land region, we study two main aspects of the Indian monsoon. The first aspect deals with the changing nature of the rainfall annual ...

An accurate seasonal prediction of Indian summer monsoon rainfall (ISMR) holds immense importance for the socio-economic well-being of South-Asian countries, as it directly impacts agricultural output and overall economies. ...

The variability of Indian monsoon on a range of timescales - seasonal to interannual to decadal - has been studied and characterised extensively over the past several decades. On the mechanistic front, the role ...

The Indian summer monsoon is a coupled land-ocean-atmosphere phenomenon that supplies about 80% of the annual rainfall that the region receives. The monsoon season typically begins on June 1 st with a steep rise in rainfall ...

India lies on the edge of the Asian summer monsoon domain and receives almost 80% of its annual rainfall during June to September (referred as Indian summer monsoon rainfall: ISMR). The dominant forcing behind inter-annual ...
