Monsoon updates: Rainfall to revive after June 24
The was weak for the last one week, but is expected to pick up again from June 24 onwards, said India Meteorological Department (IMD) latest weather update. The southwest monsoon had weakened after remaining "very active" during the first half of June. The India Meteorological Department said the "lull" in monsoon activity is normal.
"The Southwest Monsoon could not advance further since last one week due to weak monsoon flow in associations with (a) weak cross equatorial flow (ii) Unfavorable location of active phase of Madden Julian Oscillation (MJO) (iii) an equatorial eastwards propagating oscillations which lay over central & east Pacific Ocean, Western Hemisphere and Africa and (iv) development of low pressure system over northwest pacific Ocean," IMD's Wednesday morning's bulletin said.
"However,
the
monsoon
circulation
is
likely
to
improve
from
around
24th
June
with
(i)
expected
movement
of
active
phase
of
Madden
Julian
Oscillation
(MJO)
to
west
Equatorial
Indian
Ocean
and
adjoining
Arabian
Sea
during
next
2-3
days
and
(ii)
developmentof
cyclonic
circulations
over
eastern
India
leading
to
strengthening
of
easterlies
winds
over
Gangetic
plains.
As
a
result,
the
Southwest
Monsoon
is
likely
to
further
advance
over
remaining
parts
of
Assam,
some
more
parts
of
Maharashtra,
Chhattisgarh,
Odisha,
West
Bengal
and
some
parts
of
Jharkhand,
Bihar
and
MadhyaPradesh
between
23rd
to
25th
June,"
it
added.
The southwest monsoon arrived in Kerala on May 29, three days ahead of its normal onset and, over the past a few days, it has battered parts of the western coast and the northeast.
Odisha and other parts of east India would start receiving "good" rainfall from June 23-24 while Andhra Pradesh, Telangana, Karnataka and other parts of the southern peninsula from June 26, reports quoted an IMD official as saying.
According to the IMD's prediction on distribution of rainfall this monsoon, the central India will get 'normal' rainfall but the southern Peninsula - Karnataka, Telangana, Andhra Pradesh, Tamil Nadu, Kerala and Puducherry - may get 'below normal' rainfall.
The north-east India is expected to get least rainfall (below normal) during the period. The monthly rainfall over the country as whole is likely to be 101% of its Long Period Average (LPA) during July, and 94% of the LPA during August - both with a model error of plus or minus 9%.
Anything between 90%-96% of the LPA is considered "below normal" while rainfall in the range of 96%-104% of the LPA is considered "normal." Also, rainfall is considered "deficient" if it ranges below 90% of the LPA, and "above normal" if it falls between 104%-110% cent of the LPA. Above 110% of the LPA is considered "excess" rainfall.
