Description South Asia encompasses a wide and highly varied geographic region, and includes
climate zones ranging from the mountainous Himalayan territory to the tropical lowland
and coastal zones along alluvial floodplains. The region’s climate is dominated
by a monsoonal circulation that heralds the arrival of seasonal rainfall, upon which
much of the regional agriculture relies (Mall et al., 2006). The spatial and temporal
distribution of this rainfall is, however, not uniform over the region. Northern
South Asia, central India, and the west coast receive much of their rainfall during
the southwest monsoon season, between June and September. These rains partly
result from the moisture transport accompanying the monsoonal winds, which move
in the southwesterly direction from the equatorial Indian Ocean. Regions further
south, such as south/southeast India and Sri Lanka, may receive rains both from the
southwest monsoon, and also during the northeast monsoon season between October
and December (with northeasterly monsoonal wind flow and moisture flux),
which results in a bi- or multi-modal rainfall distribution. In addition, rainfall across
South Asia displays a large amount of intraseasonal and interannual variability
(Fig. 1). Interannual variability is influenced by many drivers, both natural (e.g., El
Ni˜no Southern Oscillation; ENSO) and man-made (e.g., rising temperatures due to
increasing greenhouse gas concentrations), and it is challenging to obtaining accurate
time-series of annual rainfall, even amongst various observed data products,
which display inconsistencies amongst themselves (exemplified in Fig. 1). These
climatic and rainfall variations can further complicate South Asia’s agricultural and
water management.
