Cloud seeding
Posted on November 16, 2007 | Filed Under Guest Posts
Professor T. Shivaji Rao of Gitam University in Visakhapatnam is passionate about cloud seeding for increasing rainfall.
WATER SCARCITY CAN BE AVOIDED BY CLOUD SEEDING THAT INCREASES ANNUAL RAINFALL BY ABOUT 25%
Due to the heat from the Sun the water in the rivers, lakes and Oceans becomes water vapour. As this hot moist air rises into the sky the temperature gets reduced at 7oC per km height in the sky. and the water vapour condenses over smoke and dust particles to form cloud droplets upto 20 microns[micron is a millionth of a meter] A million cloud droplets must join together to form into a raindrop of 1mm size to fall over the earth as rainfall or snowfall

RAIN FORMATION: If a warm cloud does not contain sufficient number of large size water drops or hygroscopic particles the cloud cannot give 10% to 20% of its moisture as rainfall. In cold clouds whose tops attain freezing level in the sky, insufficient number of ice-nuclei prevents the clouds from giving normal precipitation .

HOW DOES CLOUD SEEDING HELP?: If warm clouds have to give more rain we have to inject into them chemicals like hygroscopic common salt or Calcium powder into such clouds We have to inject Silver Iodide particles into cold clouds which extends into the freezing zone for about 15km into the sky. So injection of chemicals into the clouds causes additional rainfall upto 25 %
CHINA IS WORLD LEADER IN CLOUD SEEDING: In China 37,000 technicians are employed to produce additional annual rainfall of 60 billion cubic meters or 1750 Thousand Million Cubic ft which is equivalent to the annual river flow in KrishnaRiver in South India. The cost benefit ratio is estimated at 1:15. Cloud seeding is done in more than 40 countries during the last 50 years. .India must take up cloud seeding to fight the recurring droughts and also to resolve the interstate water disputes in the Cauvery, Krishna and other rivers and also to fight the damaging impacts of global warming. Although several doubts have been raised by scientists in USA and other countries Chinese Meteorologists have researched and establish that cloud seeding is not only highly scientific but is also a proven technology, if done on scientific lines.

WHY IS CLOUD SEEDING UNAVOIDABLE?: In modern times urbanization, industrialization and deforestation are increasing the environmental pollution and global warming which are preventing the clouds from giving the normal rainfall and consequently drinking water supply and agriculture production, hydro power generation and employment opportunities are adversely effected. Hence cloud seeding must be undertaken to supply more water to correct the above disadvantages.

Cloud seeding is a weapon to fight water scarcity.
****************************************************
Till date,Indian Scientific and Engineering Experts are content by blindly harnessing only the conventional surface and ground water resources although Dr.K.L.Rao,in his treatise on “India’s Water Wealth” [1979]warned that due to rapid growth of population,industries and agriculture,irrigation engineers must make serious attempts to take up cloud seeding to produce additional annual rainfall
of 10% to 20% to augment water availability for meeting the growing needs of the farmers and industrialists.As rightly pointed out by experts,Prof.T.Shivaji Rao,is a giant among world experts,as per the webs:http://unjobs.org/authors/shivaji-rao and:http://www.eoearth.org/contributor/shivaji.rao
and hence it is high time that Indian intellectuals realise that they have a responsibility to conserve water resources as envisaged by Art.51A[g] of the indian constitution.Consequently,they have to educate the public about how the patriotic Chinese scientists and engineers are working sincerely to augment annual rainfall to stop droughts and the consequential farmer’s suicides.As per ASIA TIMES,
http://www.atimes.com/atimes/China/IG13Ad01.html
Cloud seeding is very successful in several areas of China and hence Indians who are conferred with more favourable factors like Geography,Climate,Topography and higher moisture content in the atmosphere and more water content in the clouds can get by cloud seeding 40% additional annual rainfall as in Japan at a very inexpensive cost for the benefit of the farmers.
Since the elected representatives of the people in the legislatures and the parliament have not so far taken interest to follow the example of China,the people must appeal to the President of India and the Prime Minister to send a delegation of Members of Parliament including ministers and secretaries to the Union Government to visit China and submit a Report to the Parliament on the benefits of cloud seeding to China so that India can stand to benefit by cloud seeding in the fields of Agriculture,Hydro-power generation,Forest conservation and sustainable development of different states.Although many scientists are expressing doubts on the subject,it is better to take a positive approach in improving the methodology because there is no alternative to cloud seeding to solve the problems to be faced by the nation due to global warming which is already causing receding of the Himalayan Glaciers,making Ganges river face excessive floods for 3 months
and floods during the remaining 9 months of the year.Organise public debates on this crucial subject in all universities and colleges as it is a question of life and death for man and Nature.

How to overcome scepticism about cloud seeding ?
************************************************
While prof.T.Shivaji Rao,an Expert Member of Andhra pradesh state Cloud seeding project,Hyderabad and Dr.T.Srinivas,Assiciate professor of Gitam University are strongly arguing that cloud seeding is an effective weapon to fight the recurring droughts to eliminate poverty and disease burden
and the emerging impacts of global warming to save man and Nature,several scientists are raising doubts on the following lines:
1] Cloud seeding is a Zero sum game.In china there is a quarrel between the citizens of Pingdingshan and the citizens of Zhoukow about the stealing of clouds that deprived them of their normalrainfall.
2]Evaluations of cloud seeding in U.S.A.have been sceptical of the value of the operations.
3]For cloud seeding technology to work you need clouds in the first place and so there is a natural limit to its usefulness from that angle.
During the pre-independence days,India had an umpteen number of states men,patriots and socially responsible scientists.lawyers and engineers who worked with dedication to promote the cause of the common man.To-day politics has been reduced to pucca horse trading and politicians,bureaucrats,scientists and intellectuals have are no more taking social responsibilities as envisaged by Art.51A[g] of the constitution and hence even a handful of enlightened citizens must come foreward to save the interests of the farmers who are committing suicides due to accelerating scarcity of water which leads to economic underdevelopment of India.
kindly organise a debate on this subject so that people can take this challenge seriously and work out proper strategies to improve national health,wealth and prosperity.
T.V.Rama Rao.M.Com.,
To dispel the misunderstandings among the highly educated people who have a responsibility to promote cloud seeding to augment water availability for promoting on health, economy and development of developing nations which are at present hampered by the man made damaging impacts over human health and environmental assets, the basic resources for sustainable development.
Dealing with the first question relating to one Chinese city suing another for stealing its clouds, the facts are not fully correct because when the people of Zhoukow argued that their clouds were stolen by the preceding upwind city of Pingdingshan. China Daily reportedthe case of central Henan province, where five arid cities were racing against each other to induce precipitation. When the seasonal clouds passed over Central Henan region [on10 th.July,2004], Pingdingshan enjoyed a downpour of more than 100mm, but Zhoukow received rains of less than 30mm. Meteorological officials in Zhoukow accused their counterparts in Pingdingshan of intercepting and overusing clouds that perhaps would have passed over Zhoukow and givern them the normal instead of the low rainfall
But the Government experts denied the allegation by stating that Pingdingshan took permission for conducting the cloud seeding operations and hence there is no question of stealing somebody’s clouds. This question is answered in detail under the websites.
http://profshivajirao.googlepages.com/cloudseedingquestions
http://profshivajirao.googlepages.com/cloudseedingsuccessful
For the second question on independent evaluation of cloud seeding operations,the methods followed in USA (Wyoming, Nevada, Utah),Japan and Australia (Snowy Mountains] are scientific.
http://profshivajirao.googlepages.com/cloudseedingsuccessful
http://atlanta.bizjournals.com/atlanta/stories/2007/11/26/story2.html
For the third question that this technology has a natural limit based on the availability of the clouds, it must be stated that the presence of clouds is inevitable in tropical countries like India because the heat from the Sun which cannot be prevented by any person provides the required heat energy to convert the water from the seas, lakes, rivers and other sources into moist air that automatically is lifted into the sky and the condensation at higher levels results in cloud formation. Depending upon the topographical and geographical and weather features of a locality there will be convective currents that lead to deep cloud formation that sheds rain almost everyday in places like Andamans Island. In some places like Westernghats in South India the Orographic clouds during the South West monsoon naturally get uplifted to form into huge Cumulo- Nimbus clouds over westernghats which automatically provide intense rainfall over western parts of South India and the massive stream of atmospheric moisture that flows from Arabian sea and passes over South India again reforms into clouds over the forest areas and mountain belts across the country and again they give sufficient rainfall. But such rainfall constitutes only 10% of the total moisture content as scientifically established by the U.S.researchers under the Web
http://geochange.er.usgs.gov/sw/changes/natural/et/
Hence to obtain more rainfall from such clouds upto about 40% we have to sprinkle chemicals into the clouds for increasing their size for processing more moisture into rain drops and also to engulf the small clouds in the neighbourhood that may not give rain in their natural state. When good weather systems prevail such as low pressure areas , deep depressions and cyclones occur in the Bay of Bengal. Cloud convergence occurs along the trough line during the monsoons and such opportunities should be made use of for augmenting the rainfall by cloud seeding. If Rajasthan desert and the drought prone districts of North Karnataka and South Andhra Pradesh do not get adequate rainfall due to shortage of many seedable clouds, the intelligent water resources managers use cloud seeding operations in favourble areas of the catchment of the rivers and the reservoirs at higher elevations like Koyna dam in Maharashtra and Bhakranangal in Punjab and use those reservoirs for carry over storage and subsequent utilization of their water in the drought prone areas of Rajasthan and drought prone districts of Karnataka and Andhra Pradesh.
Moreover today cloud seeding is considered as very prominent and effective tool to fight against the recurring droughts, floods, cyclones and replenishment of snowfall in the Himalayas where glaciers are fast melting away due to the global warming effects. Hence application of cloud seeding operations amounts to augmentation of food production, drinking water, industrial development and economic growth while non-application of cloud seeding operations tantamounts to promotion of poverty, disease, unemployment, diseconomy, social unrest and terrorism. Hence the intellectuals have to organise continuous debates in different cities and states and take decision whether they want to promote public health and prosperity or opt for apathy towards cloud seeding that inevitably promotes poverty, disease and farmer suicide on an increased level due to the impending global warming impacts.

This controversy on the success or failure of cloud seeding operations are not because of any lack of scientific foundation for the conceptual model of cloud seeding but it is based on the commitment and efficiency of the operators and the regional geographical, meteorological and topographical feature in a given country. The Chinese have succeeded in not only reestablishing scientific foundation for cloud seeding but they also established their patriotism towards their country and also their commitment for public service by making a value the maximum additional rainfall by tapping not only the well known ground and surface water supplies but also the little known third water resource in the atmospheric clouds which contain about 10 times more water than that contained in all the rivers on earth. This high level of intenses coupled with high patriotism has enable in China to plan for production of the highest level of 65 billion cubic meters of additional annual rainfall to fight the droughts and prevent the growing suicides among farmers who are facing water scarcity loss of agriculture productivity . This additional water supply is produced at a cost benefit ratio of 1:27, with the cost of one cubic meter of water estimated at US $0.02 making cloud seeding the most inexpensive method of making available more water by the Government. The scientists and intellectuals in poor countries like India must open their eyes to these stark realities of using advances in science and technology for improving the living conditions of millions of suffering Indians who want more water for drinking, agriculture, hydro-power generation , water quality improvement, sanitation and eradication of diseases, poverty, unemployment and the growing menace of social unrest and terrorism. The Chinese intellectuals consider that non-implementation of cloud seeding operations amounts to promotion of poverty and economic ruination of the national assets in the most important countries like India, Asia, Africa and other developing countries in the world. In fact the International funding agencies like the World Bank, Asian Development Bank, International Monitoring Fund and developed countries who proclaim their slogan of controlling terrorism and promotion of world peace must request all the foreign aid received countries to spend atleast 10% of these funds for cloud seeding operations for making available more water in suitable regions for promoting the public health and prosperity of the people who have great expectations and development through foreign funding. The Universities, Colleges and High schools in all the developing countries must make education meaningful to society by demanding for implementation of the cloud seeding operations for sustainable development of the people in the long run.

Weather Modification by Cloud seeding must be done regularly in almost all the countries because with the rapid growth of unplanned urbanisation and industrialisation,Environmental pollution is crating the BROWN ASIAN HAZE which is responsible for gradual reduction in the normal annual rain-falls as amply demonstrated by the great cloud physicist of Israil,Dr.Rosenberg.Similarly,the impending evils of Global warming are again the results of indiscriminate forest destruction and forest fires promoted by the business lobby of the developed countries which are drastically causing weather modification resulting in El-Nino,sea-surface temperature Changes and melting of polar ice caps and disappearance of many Glaciers in the Himalayan and other Mountain regions.
If we have made a planned destruction of our natural resources which are causing water scarcity,we have to take the responsibility to restore such water resources by several means including “CLOUD SEEDING”which surely augments annual precipitation by about 30% to 40% at a very inexpensive cost.In fact,there is no other alternative to cloud seeding to fight the water scarcity and emerging food famine waiting in the wings.According to the cloud seeding experiments conducted in Andhra pradesh,there were many constaints like securing timely clearances from the Civil Aviation Authorities at Hyderabad and also Bangalore and so the results got diminished.In fact,unless the Union Government is genuinely interested in eradicating poverty and unemployment by making available more water to the farmers by cloud seeding,there is no salvation.
According to internatinal Experts from Texas,we must employ at least one aeroplane for every 15,000 Sq.Km.area to serve a population of 30 to 40 lakhs.See the web site:
http://www.hindu.com/2005/08/14/stories/2005081411320400.htm
But Andhra pradesh is using only about three aeroplanes for cloud seeding for about half the area of the state and hence the cloud seeding efficiency is getting adversely affected.Hence the NGO’s and educated people must come forward to educate their elected representatives to exert pressure on the Governments at the centre and the states to copy the examples of China,Thailand ,Texas,Japan,South Africa,Israil,Australia and other countries in implementing cloud seeding operations to ensure sustainable developmentof the states and the nation.

Weather Modification (Cloud Seeding) is a technology, which results extracting larger quantities of water from rain bearing clouds. The technology emerged in the late 1940s based on the experience in the Second World War. It has matured into a proper science and has been adopted by as many as 60 countries. Andhra Pradesh experiences drought at varying intervals in different parts of the state. The extended drought conditions in the Indian State - Andhra Pradesh and the sufferings of the people, especially the farmers are the top priorities addressed by the present Government of Andhra Pradesh. A special Department called, “Rain Shadow Area Development (RSAD) was formed in 2004 to give special focus to address the problems related to agriculture requirement.
Weather Modification (Cloud Seeding) was adopted as one of the measures to achieve the same and conducted operations since 2003. Cloud Seeding is a viable technology and must be conducted year after year, irrespective of the normalcy or otherwise of monsoon. Based on this Cloud seeding was conducted in 2004, 2005 2006 and 2007 resulting in rainfall enhancement. The requirement of weather modification suggests that it is essential to conduct the operations for a period of 4 to 5 years on continuous basis which helps in understanding the cloud dynamics in a typical monsoon situation prevailing in tropical environment. As such it is highly desirable to have the program and incorporate in the plan document of the Government.
