NAGPUR WEATHER in the 2011 YEAR END

THE YEAR END IS LIKELY TO BE GREETED BY THE DIVINE WATERS FROM THE HEAVENS AS FEW DROPS OF RAIN WILL MAKE THEIR PRESENCE HERE AND THERE (ONE OR TWO PLACES) AT NAGPUR (50Km dia.) AND WISH A WARM ‘GOOD-BYE’ TO THE YEAR 2011. THE MINIMUM TEMPS WILL RISE BY ABOUT FOUR DEGREES FROM THE PRESENT LEVELS OF ABOUT 11°C TO 15(-1/+2) °C.

THE WARMTH WILL BE FELT THROUGHOUT THE DAY AND THE MAINLY CLOUDY TO OVERCAST SKY CONDITIONS WILL PREVAIL.

THE Sly TO SWly WINDS UPTO 700mb WILL BRING ENOUGH MOISTURE TO DRENCH THE NAGPURians THROUGHT THE NIGHT OF31st DEC 2011 AND INTERMITTENT RAIN WILL CONTINUE TILL EARLY MORNING AND MORNING HOURS IN THE NEW YEAR i.e ON 01st JAN 2012.

THE CYCLONIC STORM 92b NOW NAMED AS ‘THANE’ IN THE Bay of Bengal WITH INITIAL Nly MOVEMENT IS NOW MOVING NWly AND WILL BRING GOOD AMOUNTS OF RAIN IN SOUTH INDIA. UNDER ITS INFLUENCE THE MOISTURE OVER THE NAGPUR SKIES WILL MAKE A THUNDERY DEPARTURE ON 02nd JAN 2012 AND CLEAR SKIES ARE EXPECTED FROM 03rd JAN 2012.

THE WIND-CHILL FACTOR WILL CONTINUE THROUGHT THE WEEK, EXCEPT ON 01st JAN THE GROUND WIND WOULD BE 10-12Kmph AND WILL GIVE LESS FEEL OF CHILL.

THE UPDATE ON THE CYCLONIC STORM ‘THANE’ WILL BE PROVIDED IN A DAY OR TWO, AS IT IS EXPECTED TO HIT THE COAST WITHIN NEXT 24-36hrs, NOW ALMOST STATIONARY WITH WNWly TO NWly MOVEMENT.

NAGPUR WEATHER IN THE YEAR END OF 2011

DUE TO SWLY WINDS IN THE MIND TROPOSHERIC LEVELS, SOME MOISTURE HAS CREPT OVER THE NAGPUR SKIES AND THE MINIMUM TEMPS HAS ALREADY STARTED TO RISE DUE TO CLOUDY SKIES. BY THE YEAR END THE MIN TEMPS WILL RISE TO ABOUT FOUR DEGREE CELCIUS FROM A CURRENT LEVELS OF 10 DEG (-1/+1) TO ABOUT 14 DEG (-1/+2). 20% POSSIBILITY OF RAIN ON 30th NIGHT/31st MNG AND SOME THUNDERY ACTIVITY MAY ALSO BE PRESENT. THE SKIES WILL CONTINUE TO BE CLOUDY THROUGHT THE WEEK AHEAD. THE ZERO DEG ISOTHERM FROM CURRENT LEVEL OF 580 mb (+/-10) WILL ALSO MOVE UPWARDS TO ABOUT 550mb AND THE UPPER WINDS WILL BE SWly FROM 28th DEC 2011 ONWARDS AND LOWER LEVELS WILL CONTINUE TO BE NEly TO Ely. HOWEVER THE GROUND WINDS (2mt) WILL CONTINUE TO ENHANCE THE CHILL FACTOR, SINCE THE SPEED WOULD BE 15 Kmph TO 18 Kmph. THUS, A 14 Deg CEL AT 10 Kts (19 Kmph) WOULD GIVE A FEEL OF ABOUT 09 Deg CEL.

Crepuscular Ray

What is crepuscular ray?

The light scattered by airborne dust, water droplets, air molecules or aerosols which provide a visible contrast between shadowed and illuminated parts of the sky is called a crepuscular ray.

This may happen either during sunrise or sunset, although not necessarily at these times.

The crepuscular rays appear to radiate outwards from the source of light due to the effects of distance and perspective, but they are actually parallel.

As observed from the earth or ground, the shadowed areas around the rays are formed by mountain tops or clouds which block the path of sun/moon light.

The artists have imagined this in the form of light being showered from the heaven by the God/s. But if we happen to see them from above the earth, say from the space, the viewing perspective gives a clear illustration of the crepuscular ray being parallel to each other.

One such phenomenon was observed over the Indian Subcontinent on 18th Oct 2011from the space station by the expedition29 crew of the International Space Station Program. A Nikon D2Xs digital camera using a 110mm lens and 4288x2848 pixel, CMOS sensor captured the phenomena, when the Sun was setting to the West (left side of the photograph) and a cumulonimbus cloud obstructed/shadowed the Sun rays which penetrated through a layer of haze beneath the CB cloud.

The following details may be noted:-

Mission:- ISS029

Date of Observation :- 18/10/2011

Time of Observation :- 113253 GMT

Nadir Point:- Latitude :- 24.0, Longitude 80.8 (Negative Numbers indicate south for latitude an west for longitude).

Nadir to Photo Centre Direction :- Sun Azimuth:- 256 (Clockwise angle in degrees from north to the sun, measured at nadir point) Spacecraft Altitude:- 374 Kms

Sun Elevation Angle:- 7 (angle in degrees between the horizon and the sun measured at the nadir point)

Orbit Number:- 2016.

(Nadir is a point on the celestial sphere directly below the observer diametrically opposite to the Zenith. Strictly it is nadir at a given point is the local vertical direction pointing towards the direction of the gravitational force at that location.

These types of photographs have a great value to the scientists and public and are available on the internet and can be viewed at the NASA/JSC Gateway to Astronaut Photography of the Earth.

The image provided here by the ISS Crew Earth Observations experiment and Image Science & Analysis Laboratory, Johnson Space Center has been cropped (by them) to enhance and improve the contrast.

SATSANG to be effective from 01st July 2013

SATSANG to be effective from 01st July 2013

The Indian Railways run daily on 65,000 Km route in India. On the run are about 5000 goods (freight) trains and 10,500 passenger trains carrying about 2.75 million tonnes of freight and about two crore passengers per day.

 In such a large system, the problem of resource allocation, rolling stock, maintain track, train scheduling, managing locomotives and crew is maintained as per the time schedule in the time table. Thus there is no place for sharing of resources or dual claim at any point of time.



A huge exercise is required that helps to enable the entire planning.

The railways are now developing “SATSANG” (Software-Aided Train Scheduling and Network Governance) which is unique in itself to handle the complex system of Indian Railways.



The various factors like impact analysis of train delays and resource constraints will be managed by robust time table software, a project being developed by “CRIS” (Centre for Railway Information System).



This will aid in more punctuality and make the railways more efficient. The new software will not only add to the benefit of the passengers but also make the planning of time table, until now which was being done manually, simple to manage the complex system of the railways.

Normally the time table is scheduled on 01st July every year. Thus next time table scheduling would be on 01st July 2012; which will be partially software aided, but the new software aided time table will be released only on 01st July 2013.
