The location of the Monsoon
Trough in its normal position during an active
summer monsoon phase (solid) and during
breaks in the monsoon (dashed).* Areas 1-4
indicate four successive daily areas of heavy rain
(>50mm/day) during the period 7-10 July 1973
as a monsoon depression moved west along the
Ganges valley. Areas of lighter rainfall were
much more extensive.
