Thought it fit to re-produce this very interesting weather fact from Jesse Ferrell, AccuWeather:

309,959,570 Lightning Strikes in Six Months:

Vaisala, the original lightning detection company that I have profiled before, sent this map showing nearly 310 million lightning strikes on Earth (specifically 309,959,570, they tell me) in the last six months via their Global Lightning Dataset:

The map looks similar to those from NASA's satellite estimates, but because it's only 6 months of data, it doesn't line up perfectly, and these are ground-based, not satellite sensors.

CPC :: Chance for above-normal precipitation for South and Southwest Bay of Bengal, Southern Indian Peninsula and the Comorin region.

Minimum temp are expected to fall by 2-3 degree Celsius over Northwest, West and Central India from Thursday onwards,. http://ow.ly/3fiH7

Chennai - Meteoron Weather service forecast says... showers to start from Midnight today ... http://ow.ly/i/5NUK

Mercury may dip over North and WET IN SOUTH

Minimum temperatures are expected to fall by 2-3 degree Celsius over parts of Northwest, West and Central India from Thursday onwards, says an India Meteorological Department (IMD) outlook.

This would happen with a calibrated reduction in cloudiness and resultant non-seasonal rainfall over these areas brought about by rogue systems taking shape and sustaining in the Arabian Sea.

But scattered rain or thundershowers would linger over many parts of West and Northwest for at least another day, the IMD said.

The causative upper air cyclonic circulation persisted over Gujarat and neighbourhood. A trough in lower levels lay extended from this system to Haryana across east Rajasthan.

Haryana, Delhi, West Uttar Pradesh, East Rajasthan, Gujarat region, West Madhya Pradesh, Konkan, Goa and Madhya Maharashtra are expected to be brought under varying wet spells in this manner on Thursday.

International model outlooks for at least the next two weeks did not indicate the possibility of a return of wet weather to this region, except briefly over the Konkan-Mumbai coast.

WET IN SOUTH

Towards the South, however, fairly widespread rain or thundershowers would occur over Kerala, Lakshadweep and Tamil Nadu.

Scattered rain or thundershowers have been forecast Coastal and South Interior Karnataka and Andaman and Nicobar Islands.

The European Centre for Medium-Range Weather Forecasts said that the week ending December 2 is likely to see a trough of low pressure hanging over contiguous Southwest Bay of Bengal, Equatorial Indian Ocean and Southeast Arabian Sea.

The Climate Prediction Centre (CPC) of the US National Weather Services attributes this to a strong but short phase of a wet Madden-Julian Oscillation (MJO) wave over this region.

The wet and dry phase of the eastward-bound wave that transits the region periodically has commensurate impact over ground-level weather.

The persisting La Nina conditions in the East Equatorial Pacific would also have a say on emerging weather in the region, the CPC assessed.

There is an increasing chance for above-normal precipitation for East Indian Ocean (adjoining South and Southwest Bay of Bengal), Southern Indian Peninsula and the Comorin region, the CPC forecast statement said.

The US National Centres for Environmental Prediction (NCEP) sees active conditions developing over the Bay of Bengal during the week ending December 1, with coastal Tamil Nadu and the Peninsular Tip slipping under a wet cover.

Parts of West Madhya Pradesh, Central Peninsula, East and Northeast India could also witness occasional showers during this period, the NCEP said.

The week that follows (December 2 to10) would once again see fairly widespread showers over Coastal Tamil Nadu coast along with Sri Lanka and the Comorin region.

Meanwhile, fairly widespread rainfall occurred over East Rajasthan, Gujarat, Tamil Nadu, Kerala and Coastal Karnataka during the last 24 hours ending Wednesday morning, an IMD update said.

Scattered rain bands originating from the Arabian Sea had reached as far northeast as West Uttar Pradesh, the IMD said. Scattered rains were recorded also over Konkan and Goa.

Insat cloud imagery on Wednesday afternoon showed the presence of convective (rain-bearing) clouds over parts of Tamil Nadu, South Bay of Bengal, Southeast Arabian Sea and the Comorin area.

The upper air cyclonic circulation over Comorin and adjoining areas of Kerala and Lakshadweep, too, persisted.

An IMD weather warning for Thursday and Friday said that isolated heavy rainfall would occur over Tamil Nadu, Lakshadweep and Kerala.

An extended outlook valid until Monday spoke about the possibility of continued and fairly widespread rainfall over Peninsular India.

WESTERLY DIPS IN

The weather-setting low-pressure area over East-central and adjoining Northeast Arabian Sea has persisted from overnight on Sunday, an India Meteorological Department (IMD) said on Monday.

Widespread rainfall were reported from Tamil Nadu and Kerala during the 24-hours ending Monday morning, an IMD update said.

WESTERLY DIPS IN

The rains were scattered over Lakshadweep, Andaman and Nicobar Islands, Konkan and Goa, Madhya Maharashtra and Gujarat while being isolated over South Rajasthan, Marathawada and North Interior Karnataka.

Meanwhile, the ‘low' in the Northeast Arabian Sea system has come under the influence of an itinerant western disturbance crossing the Northwest border and dipping south into Northeast Arabian Sea.

The IMD expects westerlies associated with the eastward-bound system to drag the ‘low' north-northeastwards towards Gujarat coast, which is in line with international model outlooks.

On Monday, a trough originating from the ‘low' arched its way across as far north-northeast as into Southeast Rajasthan.

Towards the east, an upper air cyclonic circulation hung over Southwest Bay of Bengal and adjoining Coastal Tamil Nadu.

The US Navy's Fleet Numerical Meteorology and Oceanography Centre assessed that a remnant circulation and a likely offshore trough would linger even after the ‘low' has washed over South or Southwest Gujarat.

A weather warning issued by the IMD has spoken about the possibility of isolated heavy rainfall over South Tamil Nadu and Kerala on Tuesday and Wednesday also.

Interaction of excess moisture with the band of cool northwesterlies associated with the western disturbance and day-time warming of land may combine to trigger isolated hailstorms over Rajasthan, Haryana, Delhi, West Uttar Pradesh, West Madhya Pradesh and Gujarat during this period.

Meanwhile, the FNMOC expected the rains over West and adjoining Central India to linger until Sunday.

An intervening easterly wave is forecast to dump heavy rains over Sri Lanka and adjoining Southeast Tamil Nadu coast by Wednesday.

A remnant of the wave is shown erupting in isolated heavy falls over coastal North Tamil Nadu around Chennai around Friday and later over South Kerala.

An IMD outlook valid until Thursday said that fairly widespread rain or thundershowers would occur over Kerala, Lakshadweep, South Tamil Nadu and Andaman and Nicobar Islands.

Insat cloud imagery showed the presence of convective clouds over parts of North, West and South Peninsular India, South Bay of Bengal, South Andaman Sea and East Arabian Sea.

Fairly widespread rain or thundershowers would also occur over Gujarat, East Rajasthan, West Madhya Pradesh, while it will be scattered over West Rajasthan, Haryana, Delhi and Uttar Pradesh on Tuesday and Wednesday.

Scattered rain or thundershowers is expected to occur over Coastal and South Interior Karnataka, Konkan and Goa.

The western disturbance and moisture incursion from Arabian Sea is forecast to cause scattered rain or snow over the Western Himalayan region.

This would lead to a rise in minimum temperatures by 2 to 3 deg Celsius over parts of Northwest and Central India during this period.

Extended forecast until Saturday spoke about the possibility of fairly widespread rainfall over South Peninsular India.

NON-SEASONAL RAINs for Gujarat ... http://ow.ly/3dydM

More rains to push into Gujarat, west Madhya Pradesh

The West Coast, Gujarat and West Madhya Pradesh will join the Southern Peninsula in sharing the spoils of continuing wet conditions, non-seasonal for some, during the rest of November.

Easterly wave action is expected to keep the Tamil Nadu coast busy even as residual circulations from them would cross the peninsula to keep the Arabian Sea also on the boil.

NON-SEASONAL RAIN

The US National Centres for Environmental Prediction (NCEP) expects the non-seasonal rains over Gujarat, West Madhya Pradesh and the Konkan Coast could go on during the week ending November 28.

Up to 600 per cent above the weekly normal is expected to fall over these places, according to NCEP.

Coastal and Southern Tamil Nadu and adjoining South Kerala and parts of the West Coast will continue to receive rains into the first week of December.

Contrastingly, the NCEP outlook sees below normal rainfall for interior Tamil Nadu during this period.

A six-day outlook for the period until Thursday by the International Research Institute (IRI) for Climate and Society has assessed the possibility of unusually heavy rains over entire Sri Lanka, adjoining Southwest Bay of Bengal and Coastal Tamil Nadu.

ARABIAN SEA ‘LOW'

The IRI also sees the core of rain bands sitting smack over Gujarat, West Madhya Pradesh and Sindh in Pakistan being driven by a low-pressure area in East-central Arabian Sea.

The rains would grow in intensity as one proceeds south-to-southwest from West Madhya Pradesh with the heaviest expected to fall over South and Southwest Gujarat.

Meanwhile, an India Meteorological Department (IMD) update on Sunday located the causative low-pressure area lying parked over East-central and adjoining Northeast Arabian Sea on Sunday.

The system may not likely to intensify further, but might move north-northeastwards leading to moisture incursion over Gujarat, Rajasthan, West Madhya Pradesh and even up to Delhi and South Haryana during the next two to three days.

In fact, the European Centre for Medium-Range Weather Forecasts (ECMWF) has said that the north-northeast movement (towards Konkan-Gujarat coast) of the system would be masterminded by a concurrent western disturbance from across the country's northwest border and dipping to the south.

It would not be until Tuesday that the system would crawl up to the Saurashtra Coast and drum up the proceedings to a peak, according to the ECMWF.

And, as if on cue, the IMD has kept a lookout for the next easterly wave affecting the South Peninsular Coast India from Tuesday.

This is even as fairly widespread rainfall was reported over South Peninsular India during the 24 hours ending Sunday morning from a preceding wave that hit the Tamil Nadu coast.

It was scattered over Arunachal Pradesh, Assam, Meghalaya and Andaman and Nicobar Islands and isolated over Nagaland, Manipur, Mizoram, Tripura and North Konkan.

The IMD outlook until Wednesday for various Met sub-divisions assessed that fairly widespread rain or thundershowers would occur over Kerala, Lakshadweep, Tamil Nadu and Andaman and Nicobar Islands.

It would be fairly widespread rain or thundershowers over Arunachal Pradesh, Assam and Meghalaya on Monday before reducing in intensity thereafter.

Isolated rain or thundershowers would occur over Gujarat and South Rajasthan on Monday and scale up thereafter.

Scattered rain or thundershowers are likely South Coastal Andhra Pradesh, Rayalaseema, Coastal and South Interior Karnataka, Konkan and Goa.

Widespread rain over TN, Kerala

A weather warning valid for Saturday and Sunday said that isolated heavy rainfall would occur over south Tamil Nadu and Kerala.

Widespread rainfall has occurred over Tamil Nadu and Kerala during the 24 hours ending Friday morning ahead of an easterly wave action expected to be triggered along the Tamil Nadu coast from Saturday.

All the same, the freak weather masterminded by the Arabian Sea along the West Coast persisted, with fairly widespread rain being reported over as far as Himachal Pradesh and Uttarakhand.

It was scattered over Madhya Pradesh, Vidarbha, South Andhra Pradesh, Coastal Karnataka and Jammu and Kashmir, an update from India Meteorological Department (IMD) said.

MERCURY DOWN

Meanwhile, minimum temperatures have fallen by 2 to 3 deg Celsius over Rajasthan, Punjab, Haryana, Delhi, Uttarakhand, Himachal Pradesh, Uttar Pradesh and East Madhya Pradesh during past 24 hours with some of the clouds clearing off.

However, they still continue to remain above normal by 4 to 6 deg Celsius over these regions, the IMD noted.

On Friday afternoon, Insat cloud imagery showed convective (rain-bearing) clouds driven down south to over parts of extreme South Peninsula, South Bay of Bengal, South Andaman Sea and East-central and Southeast Arabian Sea.

The upper air cyclonic circulation over East-central Arabian Sea persisted, and so did the trough from this system, though truncated and extending up to Gujarat only on Friday. But, the other weather-making trough embedded in the seasonal westerlies across the North-west border had checked in over North-east Rajasthan and neighbourhood.

WEATHER WARNING

A weather warning valid for Saturday and Sunday said that isolated heavy rainfall would occur over South Tamil Nadu and Kerala.

Forecast until Monday spoke about the possibility of fairly widespread rain or thundershowers for Kerala, Lakshadweep, Tamil Nadu and Andaman and Nicobar Islands.

It will be scattered or in the form of thundershowers over South Coastal Andhra Pradesh, Rayalaseema, Coastal and South Interior Karnataka, Konkan and Goa.

Minimum temperature is expected to fall further by 2 to 4 deg Celsius over many parts of North-west, Central and East India during the next week as colder north-westerlies begin to fill the plains.

Extended forecast until Wednesday said that fairly widespread rains would fall over South Peninsular India while being scattered over Gujarat and adjoining Rajasthan.

LA NINA OUTLOOK

Meanwhile, better model consensus is becoming evident over the tenure of the persisting La Nina event in the East Equatorial Pacific.

The strong La Nina conditions that boosted the Indian monsoon this year will continue at least into early next year, an update from the Australian Bureau of Meteorology (BoM) said. Earlier, a group of Japanese scientists at the Tokyo-based Regional Institute for Global Change had said that the La Nina might last for entire 2011 and even into 2012.

On Friday, the Climate Prediction Centre (CPC) of the US National Weather Services said that there is a 25 per cent chance that the La Nina would last into August-September-October 2011, well after the south-west monsoon for the year has ended.

‘Neutral' (neither La Nina nor monsoon-killer El Nino) conditions have been given a 50 per cent chance of sustaining while El Nino itself is being given only 25 per cent, according to the CPC outlook.

Even ‘neutral' conditions are enough to favour the cause of a trouble-free south-west monsoon for India, according to some experts.

RT @balajisanjeev: So sad, from the day I bought my new raincoat, never got to use it in Chennai. Disappointing monsoon so far..

Chennai - Another clear and warm day.. 31.3 C (10:52am), with mild breeze from East.

RT @davaps: Night temperatures dropping. If we don't have another depression in the Bay and rain, we're moving towards drier, cooler climes

Another depression is expected over S.S. Bay along 5th parallel on 20-Nov-2010... http://ow.ly/i/5tUR

La Nina - Colder Winter ... http://ow.ly/39cAc

La Nina yet to peak, may last until 2012

The currently strong La Nina condition in the Equatorial East Pacific would continue to grow and reach peak strength over the next few months, according to Japanese researchers.

The Climate Variation Predictability and Applicability Research Programme at the Tokyo-based Research Institute for Global Change (RIGC) has maintained the outlook for La Nina to last long and persist until early 2012.

COLDER WINTER

A La Nina event, in which warming anomaly shifts to the West Pacific, has traditionally favoured a good Indian monsoon as evidenced in the 2010 season.

According to Dr Jing-Jia Luo, Senior Scientist at the RIGC, the strong La Nina would bring colder surface air temperatures over many parts of the globe during this winter and the following spring.

Exceptions are the Northern Eurasian continent and Southeast North America where the odds favour a warmer-than-normal winter.

Above-normal precipitation could be expected to occur in South Africa, Australia, Northeast Brazil and South Asia (where India falls).

Cold and stormy weather might occur over Southeast China, along the Japan Sea and its coastal regions as well as northern parts of North America in early 2011.

EASTERLY WAVE

Meanwhile, back home, it emerges that the weather during the next week would be mostly dictated by an easterly wave across the Bay of Bengal.

Easterly waves travels along a straight line, and is the southerly counterparts of western disturbances that frequent the country's northern latitudes.

These waves carry their ‘payload' upfront and are fleet-footed in nature, often morphing into low-pressure areas and even cyclones.

International models, too, have indicated the straight line to the west for a disturbance that is currently located over the Andaman Sea.

‘Low's, depressions and cyclones take a trademark west-northwest track in the Bay of Bengal and travel along a southeast to northwest incline.

RAINS FORECAST

On Friday, an India Meteorological Department outlook for early next week said that the easterly wave will cause fairly widespread rainfall activity over Peninsular India with isolated heavy falls over coastal areas of Andhra Pradesh and Tamil Nadu.

The International Research Institute (IRI) for Climate and Society at Columbia University, however, said that maximum impact would be felt over southern parts of Sri Lanka.

The rest of Sri Lanka, South Kerala and adjoining South Tamil Nadu and the rest of Peninsular India would also be battered by rainfall of varying intensity during the next week, the IRI outlook said.

Meanwhile, the well-marked ‘low' over Northeast Arabian Sea washed over along the Gujarat coast and weakened into a ‘low' on Friday.

The resultant moisture incursion is still kicking up a lot of non-seasonal rain over Gujarat, Rajasthan and Madhya Pradesh.

SURPLUS RAINS

The IRI estimated that up to 280 per cent above the normal rain would have fallen over the region during this period.

It would be above 60 to 40 per cent over Central India and above 20 to 40 per cent over the West Peninsula.

The IMD said in an update on Friday that widespread rainfall was reported from South Peninsular India during the 24 hours ending in the morning.

It was fairly widespread over Coastal Karnataka, Konkan, Goa, Saurashtra, Kutch, East Rajasthan and Central India.

Insat imagery showed the presence of convective (rain-bearing) clouds over parts of Telangana, South Chhattisgarh, South Orissa, Northeast and Southeast Arabian Sea, Southeast Bay of Bengal and the Andaman Sea.

Heavy widespread showers for N. Tamilnadu coast on 17-Nov, as the first easterly wave with a LOW will reach land.. http://ow.ly/i/5s8A

Season's first Easterly wave along with a Low circulation, so 100% showers forecast from 16-Nov to 19-Nov for C and N. Tamilnadu coast.

Today, a low level circulation is still seen over S-E corner Bay for the second consecutive day.

Any chance of Cyclone Keila ?? Next week ?? .. A Low pressure system possible on 15-Nov over S Bay .

RT @esh08: Chennai - Why the F**K is it boiling hot today? I MISS the damn rain!

Chennai - Experiencing a warm day thru out.!! Max was 32.1 C (11:20am). Now 3:42pm having a deep blue sky (new weather front moving in)

RT @rajugana: @weatherofindia, Baroda 10.45am, After a foggy morning, sun peeps out.. partly cloudy sky. No rain.

Seems the clouding of "erstwhile remnant of erstwhile Jal" is persistant and far too sticky, on the western front. Now, it has crept upto Delhi region, and Delhi is receiving rains from 11.a.m. today. Some areas have measured upto 18 mms in 90 minutes.

There goes any hopes of winter recovering next few days in Delhi !Minimum today 18c (+6).

A lot was expected from Cyclone Jal for a good revival, or should I say commencemnt, of the NEM. 

But, short of hitting the East coast of India, Jal started its anomalous behaviour.

Short of striking the east coast, on the 4th. of November, it met with wind shear resistance, and started weakening, and struck the coast as a DD on the 7th.

A dryish DD ! The rain precipitation was nothing much, and lasted just for barely 12 hrs. Within 10 hrs of landfall, we were searching for Jal !

On re emerging in the Arabian Sea, on the 9th, its performance was again "unworthy" of the season. It did justice with fairly good rains along the west coast ! Karwar with 207 mms in 24 hrs was the highest. And several places in Goa and Konkan had 80- 150 mms.

Then it entered Saurashtra, where actually the people are looking to dry weather, lest their winter crops get damaged. But, on the 11th, it rained 60-70 mms in the desert region of Kutch and Jaisalmer.Central India too received heavy thundershowers.

Not to mention Mumbai, which has been receiving frequent rains from Diwali day. Today, 12th.Friday, there was drizzling in Mumbai.

And, the clouding, spreading north, has practically thrown the winter in the region for a toss.High day and night temperatures, up to +10c above normal are recorded in the NW.

No W.D. seen for NW soon.

And, the south, T.N. and interior Karnataka, are still awaiting a proper commencement of the NEM. All hopes on another system from the Bay.

Nothing in sight as on today, and no system formation seen till Monday, at least. I only hope the expectations of a good system doesnt fizzle out.

I mention this, as I see an Easterly wave. a mild one, coming towards the T.N. coast by Monday (15th.) . This would only mean a longer wait for a regular system.
