The NASA has provided estimates of monsoon rainfall that
affected India from August 13 to 20 that has devastated the south Indian state
of Kerala, located in the southwest corner near the bottom of the peninsula.
The huge rains marooned most of the state, about 370 or more people have reportedly died and about 800000 people have been displaced as a result of the extreme flooding and ensuing
mudslides.
According to the NASA, “Accumulated IMERG rainfall estimates
for the 1-week period from Aug. 13 to 20, 2018 showed two bands of heavy rain
across India. The first band appeared much broader and extends across the
northern part of the peninsula with weekly rainfall totals ranging from over
120 mm (~5 inches) towards the western half of the peninsula to as much as 350
mm (~14 inches) over parts of the eastern half towards the Bay of Bengal. This
first band is associated with the general monsoon circulation”.
NASA said that, “The second band appeared more concentrated
and intense and is closely aligned with the southwest coast of India and the
Western Ghats where onshore flow was enhanced by an area of low pressure
embedded within the general monsoon.
Weekly rainfall totals in this band are generally over 250 mm (~10
inches) with embedded areas exceeding 400 mm (~16 inches). The maximum
estimated value from IMERG in this band was 469 mm (~18.5 inches)”.
