The following piece of information makes interesting reading.
The government office of meteorology can not be depended by the nation's top scientists when it comes to weather 'predictions'!
The purpose of this post is not to discuss the already known declining standards
and the reasons for such decline.
It is about what in-house knowledge is developed on meteorology.
My suggestion is the vast number of notes of meteorology
as found in Jyothisha must be researched
and included if proved dependable.
One instance which I do with naked-eye observation is
by looking at the moon regularly.
The moon will be surrounded by an aura
when there are rains in and around a place.
We call this aura as 'pari-vEsha'.
The aura may be too close to the moon just encircling it
or may be away from it.
It may be thick and bright
By observing the parivEsha of the moon, one can say about the rainfall.
If the aura is too close to the moon,
know that it is raining in places far away from the place -
where the moon is observed like this.
One such very bright aura close to it was seen for days in Chennai some time ago
when rains lashed North India resulting in Bihar floods .
On the other hand if the aura is seen away from the moon,
know that it will rain in the place the moon is sighted like that.
Yester days' moon at 11 PM which poked out of the clouds in Chennai
was a feast to watch.
There was a thin layer of bright aura close to the moon
But a large circle of the diameter of 2 moons was spread thinly away from the moon
making it look like a huge splendid 'chakra'.
The transparent layer indicated limited rainfall in my place
whereas the close bright circle indicated good rains
in places away from mine.
This is just a sample of how heavens show up on any event.
There are a number of such indications
that can be checked and researched.
One such indicator is coinciding with the launch of Chandrayan!
October 22nd will see the moon close to
what is called 'jala nadi' – a node that ensures good rains.
If the launch is delayed, rains will follow.
If the launch is on time, cloudy skies can be expected.
The time is really good but for the Navami thithi,
which is not good for travel.
I only hope the goodies of that day over-weigh this Navami
and perhaps the time of launch (which I don't know)
will be good - holding the key for success.
But the ISRO meteorologist will have tough time
in guiding them on weather.
The basic thumb rule in astrology of rains is that
moon in gandantha - particularly in its own house of Cancer
and while passing through Aslesha and Maga
will give rains.
180 degrees opposite to that location, same results will happen.
Added to this is the location of other planets in specific nadis
about which I will write later.
That is how it was possible to experience 3 rains
(maadham mum-maari / thingaL mum-maari)
in a month in those days
as told in olden Tamil texts.
ISRO looks to its weathermen
To make the Chandrayaan mission a hassle free affair, the Indian Space Research Organisation (ISRO) is leaving no stones unturned. Satish Dhawan Space Centre (SDSC), the country's modern spaceport has been fortified and hundreds of commandos of the Central Industrial Security Force (CISF) guard the installations round-the-clock. Since the East Coast of the country is notorious for cyclonic storms during the months of October, November and December, ISRO authorities are taking extra precautions to ensure complete success of the Rs 380 crore mission, rated as the most ambitious space project of the country.
"We have drawn up a team of meteorologists from ISRO units spread across the country to monitor the weather. Seven meteorologists from establishments like the Physical Research Laboratory, Space Application Centre and Vikram Sarabhai Space Centre will start monitoring the weather from October 16," said Dr M Y S Prasad, associate director, SDSC. He said the meteorologists would monitor the weather on an hourly basis. It is interesting to note that the Indian Meteorological Department (IMD), which specialises in weather forecast, has been totally sidelined for the Chandrayaan mission. Past instances of wayward forecasts by the IMD could be the reason behind ISRO's sudden preference for in-house meteorologists. ISRO officials though were tight-lipped when asked about this new development.
"We want precise and exact weather predictions since this is a very sensitive mission," said a senior SDSC scientist. Does that mean IMD experts are not capable of providing this 'precise and exact' data?
