Chennai receives 72mm rainfall in 1 hour

Rain takes Chennai by surprise. Receives 72mm in less than a hour

— Photo: K. Pichumani.

SURREALISTIC LOOK: A slice of the rain-soaked city on Monday.

Heavy rain that lasted over an hour caught people unawares in many parts of the city and suburbs on Monday evening.

The Meteorological Department in Nungambakkam registered 70.2 mm of rainfall during the 12-hour period ending 8.30 p.m. This is much mor e than the monthly average of 53.7 mm. Meenambakkam recorded 46 mm of rainfall during the same period. The sharp showers came after a sultry day as Nungambakkam and Meenambakkam recorded a maximum temperature of 38.4 degree Celsius and 38.8 degree Celsius, one degree above the average temperature this month. Several localities in and around the city, including Aminjikarai, Anna Nagar, T.Nagar, Koyambedu and Pallikaranai, experienced heavy showers accompanied by loud thunder. Some interior roads, including Arunachala Naicken Street at Chintadripet, were flooded. Besides affecting the traffic on arterial roads, many bus services were also hit.

The scattered materials near the Metro Rail project site at Kathipara junction following rains aggravated the traffic snarl on the stretch. Traffic was thrown out of gear for a couple of hours around Guindy and Saidapet with vehicles piling up for prolonged period of time. Murky sky and heavy showers around 7 p.m. took motorists by surprise and many of them took shelter under trees and shops. V.S. Rajkumar, a resident of Nerkundram, said “I had to wait at a teashop for almost 20 minutes until the rain subsided.” Residents of southern suburbs such as Medavakkam, Perungudi, Sholinganallur and Velachery complained of power cut for almost an hour.

Officials of the Meteorological Department said heavy downpour within an hour was caused by thunderstorm activity. However, such rainfall in June was not unusual. Last year, 53.4 mm of rain was registered in 24 hour period on June 28.

The highest recorded rainfall in a single day was 347.9 mm on June 14, 1996. (Which was accompanied by Tropical Storm) The department forecasts that the rain or thundershower would occur in some areas of the city and the maximum temperature would be 39 degree Celsius.

Shanghai sees its longest no precipitation period in 138 years,

Shanghai is currently experiencing its longest period of no precipitation in 138 years, according to a report released on Monday by the Shanghai Municipal Meteorological Bureau.

Shanghai's urban areas have recorded just 132.9 mm of rainfall since the beginning of this year, the lowest level since 1873, said the report.

Shanghai already experienced a dry and cold winter last year, with the the lowest average temperatures recorded in the city since 1978, the report said.

Bookies place their money on rainfall

Manish Pachouly, Hindustan Times
Mumbai, May 30, 2011

With the IPL-4 season having drawn to a close, bookies across the city have moved on to their next target: rainfall. On Sunday, the city’s bookies opened rates for the amount of rainfall Mumbai would witness from June to September, with every millimetre of rainfall expected to fetch more than Rs1.5 crore.

Bookies expect a business of approximately Rs3,500 crore this monsoon and predict that the city would witness a seasonal rainfall of around 2,100-mm.

In a first, bookies have opened seasonal rainfall (the total rainfall from June to September) rates for not just Colaba, but also Santacruz.

Bookies have also opened rates for monthly rainfall (in individual months, beginning June and ending September) in Colaba. “In case of Santacruz, we have only opened seasonal rainfall rates and not monthly, as this is the first time we have placed bets for rains expected in the suburbs. Depending on the response, we will decide if we should open monthly rainfall rates in Santacruz from next season,” said a bookie on condition of anonymity.

Sources said that bookies from Delhi, Indore, Ahmedabad, Guwahati, Jaipur and Kolkata had come to Mumbai to open rates for rainfall in the city.

“Bets not only come from Mumbai or from within the country, but even from Dubai, Sharjah and Pakistan,” said the bookie.

He added that most high-profile bookies have internet-enabled mobile phones and they update themselves on the rainfall figures released by the weather bureau everyday, even while travelling across the city.

Bookies expect the monsoon to arrive in Mumbai between June 11 and June 13. “Experts in opening rates for Mumbai rains are keeping a track on when the monsoon arrives in Andaman and Nicobar, and Kerala,” the bookie said. “After the monsoon arrives, the rates would be updated depending on the rainfall the city receives,” he added.

You wait ages for a massive waterspout, then FOUR come at once

By Ted Thornhill, Daily Mail

Four colossal waterspouts swirled around off the coast of Sydney today amid dramatic thunderstorms. The gigantic twisters - created when tornadoes form above the sea – occurred near Avoca Beach, which lies just to the north of Australia’s capital.

The amazing natural phenomena caused a huge stir with locals, some of whom had lived in the area for over 50 years and never seen one.

Local Tracey Boxsell, told 9 News: ‘Someone knows a man who has lived here from when he was five, and he is now in his 60s, and he has never seen anything like this.

‘It definitely doesn’t happen often. It was amazing, very spectacular. We're not used to seeing one let alone four. We were in awe of it.’ The waterspouts were filmed from a helicopter and by a motorist, who pulled over and produced incredibly dramatic footage.

Waterspouts are created when tornadoes develop over the sea.

Layers of cool air blowing over the water cause warm, moist air to sweep up from underneath and form a column of condensation. They can move as fast as 80 miles an hour, and inside winds can spiral from 60-120 miles an hour.

The 'water twisters' can last up to half an hour and posed a considerable threat to boats and aircraft - they are also known to damage coral reefs. They are most common in the Florida Keys, where there can be as many as 500 each year - though there are also around 15 reported every year off the coast of the British Isles.

Like tornadoes, they can often pick up and transport strange objects. A Canadian waterspout once carried lizards across the sea and dropped them in Montreal. In Providence, Rhode Island, a waterspout even caused fish to rain down - which the people below promptly sold. The Avoca Beach twisters came as forecasters warned of heavy rain and flash-flooding along the Sydney coast.

Jeddah receives 111 mm in 3 hours and exceeds Nov 2009 flood accumulation

JEDDAH: In just three hours Wednesday morning Jeddah was inundated with 111 millimeters of rain, the King Abdulaziz University's (KAU) Meteorology Department said. Mansour Al-Mazrouie, head of the department, said Wednesday's volume of rainfall exceeded the 90 mm recorded in four hours during the Nov. 25, 2009 flash floods that killed at least 123 people and damaged thousands of vehicles and homes.

The average amount of rain during the winter months (November to January) is about 51 mm. He said what Jeddah is presently witnessing is due to climate change. As of Wednesday afternoon, reports of three electrocuted teens, hundreds of stranded students and a broken dam were pouring in from different parts of the city. Civil Defense officials, however, said there were yet no reports of any deaths related to the flooding.

Eyewitnesses told Arab News that East Jeddah was swamped and floodwater was rushing west toward the Red Sea, turning streets into rivers once again. Witnesses say Um Al-Khair dam has been breached, flooding nearby neighborhoods. Water in Al-Hamra district was waist-deep in some places and some schools were keeping students from leaving. The heavy downpour did not begin until after students went to class where they are currently taking end-of-semester exams.

Unconfirmed reports came in saying three female students were electrocuted at KAU. It was not immediately clear if any of the young women were killed in the accident. Palestine Street, Madinah Road and Wali Al-Ahad Street were either flooded or jammed with traffic. Cars were seen floating in some places. Three hundred students at Dar Al-Hekma were still held up inside the college. At Effat College the situation was the same. Civil Defense advised tudents not to leave the premises and wait till the floods subside. Civil Defense officials, meanwhile, urged the public to stay home if there was no urgency to venture outside.

Maharashtra begins artificial rain project

For the small pockets of land in Maharashtra that received very modest rainfall on Saturday and Sunday, its was a man made gift of showers. Four very small pockets of land in Satara (Wadunj) and rural regions of Pune district (Daund, Baramati and Marinagar) received from a maximum of 11 millimeters (mm) of rainfall for 31 minutes on a 12 square kilometer tract of arid land to an almost abysmal 6.5 mm of rainfall for even lesser time.

Why the jubilation then? Because these regions fall within 10 most scarcity-hit districts of Maharashtra with no rains for the last three years. The state government has imported the requisite radar machines and other equipment at a cost of Rs.5.5 crore and hopes to continue creating artificial ‘November rains’ equipped with a Piper Cheyenne plane (light aircraft), armed with hygroscopic salts, for cloud seeding sorties over these and other scarcity hit regions.

Chief minister Sushilkumar Shinde said today: “The artificial rain is the outcome of an agreement signed between the state government and Ms Weather Modification Co through its subsidiary Ms Agni Aviation Consultants (Bangalore) on August 21, 2003. The equipment was imported and became operational on Saturday with the first experiment resulting in 11 mm of rainfall experienced over a 12 square km patch in Satara district for 31 minutes. The next day (Sunday) the same experiment was repeated in the three rural regions where around 6.5 mm of rainfall was recorded.

Cloud seeding is here to stay and will provide a shower of man induced artificial rainfall upon regions bereft of nature’s annual generosity. The state government has set up a control room in the Vidya Prathisthan located in Baramati from where sophisticated radar will monitor the availability of cumulus clouds drifting over the parched landscape that can be targeted and fueled with enough hugroscopic salts (shot into the base of the cloud).

Rains this season create records in Mumbai, Delhi, Jaipur & Dehradun

Mumbai - breaking 50 year record

Monsoon has created a record of sorts this year. The rainfall witnessed is well on course to be ranked as the highest ever recorded in the city. There have been a number of intense rain spells, yet the city life has not been thrown out of gear even once. The data of monsoon witnessed between 1999 and 2009 indicates that there had been at least two rain days every year when the city life was halted, a senior official from the civic disaster management cell said. The Santa Cruz observatory has witnessed 3,309.2 mm rain this year, while the Colaba observatory has received 3,160.5 mm. A Met department officer said that with there being still some time before the monsoon withdraws, the rainfall-recorded is on course to be the highest ever. According to a senior official, the Santa Cruz observatory had recorded about 3,400mm rainfall in 2005, the year when an unprecedented rain event on July 26 saw a downpour of 944 mm. The second-highest rainfall recorded by the suburban observatory was 3,281.7 mm in 1958. The Met officials also suggested that the Colaba rainfall has already surpassed all rain records set in the past 50 years.

Dehra Dun - breaking 44 year record

The monsoon rainfall broke a 44-year-old record in Dehra Dun by registering a whopping 3088 mm of rainfall this season. Met Director Anand Sharma told PTI that the previous highest record was in 1966 when the Doon valley recorded 2930 mm of rainfall. Before 1966, records regarding monsoon rains are not available, he said. With heavy rains lashing Dehra Dun, several rivers in the valley were on spate which include Rispana, Bindal and Asan. Nine of the total 13 districts of Uttarakhand have received excess rainfall this monsoon season.

Jaipur - breaking 14 year record

Breaking a 14-year record, Jaipur received 781.2mm rain this year till Wednesday. Going by the Met department’s prediction, as the monsoon is still active in the state and will last till the end of the month, the figure is likely to change in the coming few days. According to officials of Indian Meteorological Department, Jaipur receives around 500 mm rainfall in normal circumstances. The last time it had rained so much was in 1996, when the showers had been plentiful to the point of becoming an abnormality. Jaipur city had then received 850 mm rain between June and September. Looking at the conditions of this year, Jaipur is heading towards and abnormal spell of monsoon. "The district has already received 40% rain in excess of the normal this year," an irrigation official said. The comparison becomes obvious with last year's rainfall chart when Jaipur received less than 300 mm rain and had to be included among the scarcity-hit districts of the state.

Delhi - breaking 32 year record

Records shows this is the wettest monsoon in Delhi since 1978. Rainfall since June 1 has touched 1004mm higher than 965.1mm recorded during the monsoon of 1978. Sunday's rain also took Delhi's rainfall during September to 250.6mm, the highest since 1998 when 280.4 mm was recorded. Last year, the figure had settled at 588 mm. Delhi recorded 455.1 mm rain in August, more than double its normal average of 225.8 mm. With 10 days remaining in the month, September too is poised to break records having recorded around 280mm more than normal.

Agumbe vs Hulikal - The wettest place in South India

Agumbe in Thirthahalli taluk of Shimoga district is dubbed as the 'Cherrapunjee of the South'. But Cherrapunjee itself is no longer the wettest place on Earth. It lost its crown to Mawsynram, also in Meghalaya.

Only 5 places in India get above 750 cm rainfall. They are Cherrapunjee, Mawsynram, Agumbe, Hulikal & Amboli

In peninsular India its Agumbe which always takes the top spot. A new challenger in the form of Hulikal in Shimoga District has been rumoured to get more rainfall. A comparison of rainfall from 1955-1970 shows that there is nothing between the two places with Agumbe getting average rainfall 0f 799 cm while closely followed by Hulikal at 776 cm. But in terms of Intensity its Hulikal twice crossing 1200 cm mark in 1959 & 61. IMD has to publish these two stations data for the recent years through which a comparative study on these rain forest stations can be made.
