c indicates a significant increase in ET over the
whole subcontinent region, again with largest increase over Indus and southern India.
The reduced differential heating of the land relative to the ocean leads to a reduction in
the too strong westerly winds from the Arabian Sea into the Indian plains (Fig.

d). This
creates conditions favourable for monsoon depressions originating from the Bay of Bengal
to intrude deep into the land up to western India and Pakistan. Saeed et al. (

illustrate this behaviour for the development and movement of several monsoon depres-
sions that brought rainfall to the western part of the Indian peninsula and that have been
