Figure 8 Geographic map of India, showing the location of
Gopalpore ? Sambalpore and Surat ? Dahod, their
inter-distance, inclination from latitude and longitude; and
relationship with neighbouring seas
Table 2: L-Su is much more breezy than L-Go while
L-Da is more windy (strong) than L-Sam. L-Da as
alike L-Sam has half a year of no clouds, while L-Sam
has much more rainfall (1 500 mm). That L-Da has a
very steep annual average barometric gradient (~40
hPa) as compared to Surat (coast line); which is very
sterling and significant. World wide, such low
pressure is normally associated with deep
depressions/thunder storms (i.e., heavy rain bearing
synoptic & meso scale systems). However, L-Da has a
rain fall range between 300 mm (in draught year,
which is normal) to 1 300 mm as in good years (2007
& 2010).
This is very low precipitation with ultra high
variability. Hence, L-Da’s is always marked by crop
and even grass-land failure as compared to all India
similar-inland location basis, specially.
The lowest rain fall in L-Sam is more than the amount
that precipitates over L-Da in the L-Da-best monsoon
year. Yet the relative humidity and temperature
between L-Sam and L-Da are almost similar! Again,
L-Sam is green. Its neighbourhood district of Bargad
also cultivates paddy round the year and consumes the
highest amount of fertilizer on district basis (record).
L-Da not. Further, Odisa experiences as many as 6~10
monsoon period depressions per year. In 2006, India
had 16, of which 14 had crossed Odisa
s coast line &
record repeat floods. Annually, L-Da may\may not
experience even a single rain bearing weather system;
whereas the entire eastern sea board of India
(
including Gopalpur & L-Sam) annually experiences
Cyclones & Tornadoes, which is another distinctive
feature (Bhattacharya et al., 2011).
A consistent ‘deep-low’ should have acted as
attractant (natural gradient) for the sea based
met-depression to home in on-towards L-Da (sea is so
close by, and not in the lee of any highland, which is
so in the case of L-Sam). That does not happen
(
subsequent communication). Unique indeed. The
Indian nation is triangular peninsula, either coasts of
which are cyclone prone

Discussion
Discussions among others throws light onto the
possible inspirations, collateral matters and levitates.
Among the few sciences that ancient India seems not
to have was the system of recording constituent
elements of the diurnal-nocturnal weather. Going out
into the mid-day sun or the dark of the night for
astronomical recordings was strongly in vogue even
pre to The Christ. Not for meteorological purposes. In
c. 1864 a catastrophic storm had struck Calcutta (the
London of the eastern hemisphere). It was British
dominion period. Subsequently, due to monsoon
failure and tackle less export of rice from India to war
ravaged and hungry UK, Odisha famine (c.1866) and
Bengal famine (c.1940
-
42)
followed in quick
succession in which had perished around 2~3 million
natives. UK had deficient farm production between
1940
~1942 and famine like conditions. The British
govt., had thence set up the 1
st
weather observatory
(
at Alipur,
Calcutta. The India Meteorology Dept., transpired out
of such beginnings (c.1877). Logically, learned &
polite Englishmen were in charge. But, mad dogs and
Englishmen go out into mid day sun, goes the saying.
The IMD (alike all other British set India-professional
institutions, inherent traditions) thus for over a century
(1880
~2000) went out to the field, into the sun & rain,
sweat & dust, hand collected hard data, validated
in-situ and recorded it. Such data are unassailable. We
are bound to it. Our Table 1 reflects an infinitely
miniscule part of the IMD’s pan-data bank (Indo
coast-to-coast). It is a veritable store house.
