After 2 years of round-the-year observation of
astro-meteorology, I have zeroed in on certain features as most reliable ones.
They are three in number.
(1) Solar or Margazhi Garbottam that lasts for nearly13
days. This is the time Sun is moving across Purvashada (Pooradam). Each day of
this period corresponds to roughly 13 days of Sun’s transit in a star starting
from Arudra which happens in June, that is., Vaikasi.
(2) Daily Garbottam which is to be watched every day
from December to July. Every day of this period corresponds to 195th
day later. Presence of Garbottam on a day is indicative of rainfall after 195
days.
(3) Planetary combinations that support or spoil
rainfall at the time of rainfall.
All the three are supposed to work in tandem and
must work in tandem to ensure good rainfall. In 2016 they were so and we found
only less deviation. Whether rainfall is good or bad, these three must indicate
the same thing.
The situation is a little different in 2017 as we
find non-concurrence within these three. When non-concurrence is there, which
one takes the lead is found out in this year’s situation.
This year (2017) there were 2 major planetary
combinations - one occurred in SWM and another (others) in NEM season. The
former one was a singular event of Venus in eastern sky in the morning
transiting stars Magha to Chitra between Sep 15th and Nov 8th.
This corresponded to Solar Garbottam which was posted on 12th
Dec, 2017 The relevant part of the table from that post is reproduced
below. It rained during this period till Venus completed this transit on 8th
November.

One can notice that Solar Garbottam gave dry days
from the 2nd week of November till the end of December with only a
few days (6th to 10th Dec) showing rainfall. This means the major
part of NEM 2017 is dry.
Coming to the planetary combinations, the last set
of planetary combinations for the year in support of rainfall started on 13th
December (Venus- Mercury closeness) while another set started on 16th
December. This happened almost in the fag-end of the NEM season. Both of them
continued till December end with the former ending on 9th January
2018 and the latter on 14th January 2018.
The reality check shows that the planetary combinations didn’t work in the
absence of Solar Garbottam.
The potency of these sets of planetary combinations cannot
be doubted as we saw the dates of their occurrence tallying with the directions
exactly – but not within the location of NEM. For example, the western section
indicated by them pulled cyclone Ockhi to west of India, to Lakshadweep and
Mumbai. The North- North east indicator which in normal circumstances should
have helped northern limits of NEM regions, dragged it to NE India and
Bangladesh. What was South West went beyond India and benefited Arabian Peninsula.
What was east rained at Philippines!
Witnessing all these, the inference we can make is
that in the absence of Solar or Margazhi Garbottam, the rainfall expected over
larger regions under the aid of planetary combinations do not necessarily
materialise.
For Chennai, the local Garbottam also was for a few
days in NEM and that is what had happened.
In this NEM (2017) 2/3 features did not support
rainfall for Chennai. They are Solar Garbottam and local Garbottam. Even though
3 sets of planetary combinations were present from 13th December
onwards, they could not bring in rainfall.
Since the same trend is found throughout Tamilnadu,
I have to assume that solar and local Garbottam were negative for rest of TN
also. If more people start watching Garbottam in their respective regions at least
during the Solar Garbottam, it will be useful to draw better inferences.
PS.
I am planning to start a blog exclusively for astro-weather
prediction. I will start posting the basics of Garbottam and how to predict
rainfall through that. Initial post will be intimated in the current blogspot
while no more weather posts will appear here. Interested ones are kindly asked
to follow that blog (after the announcement is made here). However I will be regularly
tweeting my posts of the weather blog.
