Head to Snow World at Abhirami Mega Mall. The spacious place takes you to a world of snow that makes you to forget the heat. The snow world is made of 50 tonne snow that is made from purified mineral water that are kept frozen in -10 degree celsius. This first of its kind snow world has special effects to haunt you. It has a thunder and lighting effects. Besides that it can drench you in a snowfall with its 140-kilometre speed snowstorm. There is also a 50 feet high fiery slide, which not just kids, but elders too can slide and have a great fun. Though, there is nothing that can stop a person at the end of the slide, when a person slides down, the person might only hit the iron rods that acts as a fence to the automatic fan that creates the snowstorm.

There are also the ice sculptures (crystal museum) that one can watch and enjoy besides the large Eskimo house that kids can play in besides making ice balls, playing in the snow and taking a ride on the wooden sledge. For a fee of Rs 150, a person gets a thermal coat and boots that can keep you warm.

Network of Research Buoys in Indian Ocean to Improve Monsoon Prediction

Indian Ocean Buoy.(Credit: NOAA)

A new array of moored buoys in the Indian Ocean will provide critical climate and ocean data to help scientists predict the dramatic variations between seasonal monsoon rains and droughts.

"The data from these buoys will provide us with much-needed information to advance our understanding of the oceanic and atmospheric processes that govern the monsoons," said Michael McPhaden, an oceanographer at NOAA's Pacific Marine Environmental Laboratory in Seattle. "We want to improve computer models for seasonal forecasting to benefit farming communities and other weather-sensitive sectors of society."

McPhaden and nine co-authors from Australia, China, France, India, Indonesia, Japan, and the United States describe the Research Moored Array for African-Asian-Australian Monsoon Analysis and Prediction (RAMA) in the April 2009 Bulletin of the American Meteorological Society. The paper's co-authors represent a range of monsoon-affected nations that support the array and participate in monsoon research.

The array was established to collect important oceanographic and meteorological data from the Indian Ocean, which is "the most poorly observed and least well understood of the three tropical oceans," write the authors.

Instruments on the moored buoys measure winds, air temperature, rainfall, relative humidity, water temperature, salinity, and ocean currents. These data characterize the movement of mass and energy throughout the Indian Ocean basin and are essential for developing better monsoon computer forecast models.

Monsoon rains in Africa, southern Asia, and Australia are critical for growing the food that supports a third of the world's population. However, these seasonal rains are irregular, sometimes leaving an area parched by drought in one year and inundated by floods in the next year. The ability for scientists to accurately predict monsoon conditions even one season into the future would greatly improve farmers' chances for successful harvests.

"Data from RAMA helps farmers make informed decisions on a range of practices such as cropping programs, fertilizer and spray applications, and the number of animals to keep on their property," according to the authors. "This helps them better cope with climate-related risks and capitalize on the opportunities."

In addition to improving prediction of the monsoons, "conditions in the Indian Ocean have a long-range effect on North American weather and climate, so RAMA will pay dividends in our own back yard as well," said McPhaden.

By the end of 2008, instruments had been deployed at 22 of the RAMA mooring sites. Contributing organizations intend to complete the full array of 46 moorings by 2012.

NOAA understands and predicts changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and conserves and manages our coastal and marine resources.

Clouds preparing for the monsoon

Going by the present prevailing wind pattern and other parameters. And by looking at the latest FULL satellite pic, it seems the "Monsoon" is getting cooked along the 5th Parallel over South-Arabian sea.

More cloud formations can be seen over Andaman sea.

Latest "Total percipitable water" chart also shows a increase in "energy" along the 5th parallel of south-arabian sea.

South west monsoon - predicted much earlier

Take a look at the latest NCEP percipitation forecast.

This suggests more rain activity (Monsoon like activity) to the South-west coast around 20-May-09.

Chennai missed a Thunder storm (video)

Chennai missed a Thunder storm yesterday (5-May-09) at around 10:30 pm.
From 4pm it was cloudy with High clouds moving in from west... those are remnants of a early thunder storm.
Chennai's western suburbs got some rain.
Going thru the latest satellite loop, shows that the thunder cells dissipated quiet quickly after 11pm.
This video shows lot's of thunder activity thru out the country.
New delhi also received some showers.

on 3-May-09, "Lightning, thunderstorm claim six lives in Bengal "

Altogether six people were killed in lightning and thunderstorm-related cases in three separate incidents in Malda district as Nor'wester hit the state this afternoon.

Additional District Magistrate Bipul Biswas said two persons were killed when lightning struck them at Manik Chowk under Mohanpur block. The deceased were yet to be identified, he added.

In another incident, two persons died on the spot when a tree fell on them at Kaliyachowk in the district, Mr Biswas said adding two more persons were killed in the related incident when their hutment, in which they were staying, collapsed on them due to strong winds at Englishbazaar in the district.

At least 200 hutments have been damaged by the storm, while mangoes and lichies amounting to Rs 20 lakh were damaged, he further informed.

The state witnessed season's first Nor'wester today which also brought much sought after relief to the denizens as raingod finally smiled on Kolkatans and Southern parts of West Bengal.

Cool Nor'wester speeding almost 40 to 60 km per hour along with thunderstorm and rain have significantly brought down the temperature.

Local Met office recorded the maximum temperature at 36 degree Celcius and minimum at 28 degress Celcius.

The state was reeling under heatwave-like condition for the past one month.

The much-awaited Nor'wester also forced a number of flights to defer landing at Netaji Subhash Chandra Bose International airport here, air port officials said adding they were directed by the Air Traffic Control (ATC) to "hold" and circle over the city and wait for the storm to abate.

Moreover, the Met officials forecast cloudy sky with rain and thundershowers towards the evening tomorrow

The Global Dry Toilet Association of Finland is a registered Finnish association founded in 2002 to promote the use of dry toilets.

Their vision is to make dry toilets an essential part of sustainable development, thus securing clean waters and a healthy environment for future generations. Our mission is to introduce functioning dry toilets together with controlled management of toilet waste and to make people aware of the benefits of dry sanitation.

A working toilet is one of the basic needs for humans. Poor toilets and inadequate waste water treatment can lead to pollution of surface and groundwater reservoirs. However, it is not necessary to use water to have modern and hygienic toilet facilities. Dry toilet technology offers variety of choices from summer cottages to stylish bathrooms.

Dry Toilet

Benefits of dry toilet:

• saves pure drinking water
• makes waste water management easier
• can be installed and maintained by your self
• works regardless of weather conditions through electricity block outs, droughts and frozen water pipes
• collects the nutrients protects water systems
• doesn't pollute ground water reservoirs.
A Dry toilet saves clean water. A normal water closet uses from 5 to 15 litres of water per flush. Dry toilet doesn't need water to function.

Westerlies blow off the heat in Northwest India

Original from: http://www.thehindubusinessline.com/2009/05/04/stories/2009050450420500.htm

Cooler winds from a passing western disturbance helped rein in the runaway mercury in Northwest India but no such relief was there for the asking in Central East-Central India during the past 24 hours ending Sunday morning.

But dry and hot westerlies blowing into the peninsula continued to curve around the peninsular tip to head north and even cross the east coast to sustain the wind discontinuity/trough along the coastal interior.

MOISTURE CARRY

Moisture carried by these winds is being dumped as isolated showers along this formation, especially over soastal Andhra Pradesh and south interior Karnataka.

Some of the activity spread to the immediate north and northeast, with parts of West Bengal, Sikkim, Orissa and the north eastern States too witnessing some weather.

thunder squall forecast

Isolated thunder squall has been forecast to continue over these very areas for two days more. Similarly, the Regional Met Centre, Chennai, expected thundershowers to continue over interior Tamil Nadu, Kerala, Rayalaseema and south interior Karnataka.

SCORCHED EARTH

But the pre-monsoon sun continued to scorch the earth in central and east-central India.

The highest maximum temperature of 46.6 deg Celsius was recorded at Nagpur, but Darsi in Andhra Pradesh clocked 47 deg Celsius as per hourly automatic weather station data.

India Meteorological Department (IMD) said in its update that heat wave conditions had abated from Rajasthan, Haryana, Delhi, Uttar Pradesh and west Madhya Pradesh.

But they continued to hold strong over parts of Vidarbha, interior Orissa and isolated pockets of east Madhya Pradesh, Jharkhand, Himachal Pradesh, Punjab and Chandigarh.

MAY ABATE

The eastward movement of the western disturbance is expected to help in the abatement of the heat wave conditions over these areas as well from Monday, the IMD said in its outlook.

The prevailing western disturbance would trigger scattered rain or thundershowers over the western Himalayan region during the next three days.

Isolated dust storm or thundershowers accompanied with squall have been forecast over the plains of north west India across Punjab, Haryana, Chandigarh, Delhi, Rajasthan and Uttar Pradesh. This is expected to bring down the maximum temperature by a further 1 to 2 deg Celsius.

Rain or thundershower has been forecast over Jammu and Kashmir, Himachal Pradesh and Uttarkhand. Thunderstorms with squalls are likely at isolated places over Uttar Pradesh, Punjab, Rajasthan, Haryana, Chandigarh and Delhi.

MONSOON BUILD-UP

Meanwhile, the US National Centres for Environmental Predictions (NCEP) continued to signal initially hesitant coverage of the Bay of Bengal by what appears to be the seasonal (southwest monsoon) rains during the week ending May 10.

But forecasts for the week that follows (May 11 to 19) show rains unravelling over Kerala spearheaded by a low-pressure area over the south-east Arabian Sea.

This is also the time when an eastward bound and pan-global Madden Julian Oscillation (MJO) wave is predicted to sit over the Southwest Arabian Sea and the adjoining equatorial Indian Ocean.

Periodical MJO waves with alternating wet and dry phases have been known to sit over monsoon onsets and intra-seasonal excess rain spells in the wet phase and the `break-monsoon' in the dry phase.

Meteorological experts swear by an early monsoon onset for India this time around - their only matter of interest being how early the onset could actually turn out to be.

storm sweeps across Nepal

We were following this FREAK storm crossing much of Nepal till morning of 3-May-09, and later in afternoon the remnants of it erupted as HUGE electric storms over Bihar, west bengal and Bangladesh.

At least seven people were killed and dozens injured by a storm which struck many places in Nepal, officials said Sunday.

In Rautahat district, about 120 km southeast of the capital Kathmandu, at least five people, including four children, were killed when they were crushed by a roof which collapsed after the storm hit the area, the police said.

'The five were crushed by a falling roof after their homes were damaged by the strong winds,' said Ghananand Bhatta, Superintendent of Police of Rautahat district. 'More than 70 people were injured either by flying debris or were caught in collapsed houses.'

Police said nearly 400 houses in four villages were damaged by the storm which hit the district early Sunday morning.

Two more people died in Gorkha district, about 120 km west of Kathmandu, when they were struck by lightning. In the eastern district of Mohattari, seven students were injured in a wall collapse.

The country's meterological department said the storm system had now moved away into northeastern India.

'The storm was produced by a major system which affected much of the country Saturday night and Sunday morning,' meteorologist K.B. Malla said. 'It was accompanied by strong winds and heavy rains in some areas.'

Malla estimated that wind gusts of up to 60 km per hour accompanied the storm, but said a full report was only expected later Sunday.
