Baipatra - Climate Change Impact on Water Based Energy Sources

What's New ?

06-07-2014 : Change of Retention Indicator ((c)Baipatra) : The watershed retain some water from the rainfall which is used by the human as well as animals to sustain their livelihood.....

06-07-2014 : Climate Change Indicator : Everyone is worried about the worldwide change in climatic pattern.But what about my place ? Is the climate of my place is also changing ? Let us use this simple indicator to know whether climate is really changing in my place or not.

06-07-2014 : CLOUD BURST ? : Define : Rainfall Rate >= 100mm/hr. Result : Splash Flood. Example : Cloudburst in Leh,India in August 5,2010. Cause : ".... the Langmuir precipitation process in which large droplets can grow rapidly by coagulating with smaller droplets which fall down slowly. It is not essential that cloudbursts occur only when a cloud clashes with a solid body like a mountain. They can also occur when hot water vapor mingles into the cold resulting in sudden condensation...."

06-07-2014 : Can you predict the occurence of Cloud Burst ?? "The rains that caused widespread devastation in Uttarakhand may help avert heavy loss of human lives in future. Data generated during the spell of heavy rains can be used by scientists to predict events of cloudburst. Scientists at the Space Applications Centre (SAC) in Ahmedabad that functions under Indian Space Research Organisation (ISRO), will use the data to improve their experimental model for cloudburst forecast. The model is likely to be in use by next year's monsoon. "(Down to Earth,2013).

06-07-2014 : Reliability of Cloud burst Prediction : The prediction of occurence and location of occurence of cloud burst has to be interconnected with both temporal and spatially variable data.But level of uncertainity in such kind of predictions will be large.Accuracy level of short term weather forecasting(STWF) models are low ("For very short prediction periods (0 to 6 hours) principle interest centers on small-scale, short-lived, often violent phenomena, such as thunderstorms, tornadoes, as flash floods, and on localized nonviolent weather such as dense fog and freezing rain") and to predict cloud burst we will need STWF models.

06-07-2014 : Cloud Burst Impact : An area not exceeding 20–30 sq.km."Cloudburst events occur at the meso-gamma (2–20 km) scale as defined by Orlanski (1975) and may be difficult to distinguish from thunder-storm". (Das et.al.,2006).

06-07-2014 : The main causes of changes in climate according to Environmental Protection Agency :

1.Changes in the greenhouse effect, which affects the amount of heat retained by Earth’s atmosphere.
2.Variations in the sun’s energy reaching Earth.
3.Changes in the reflectivity of Earth’s atmosphere and surface.

06-07-2014 : The Green House Gases which enforce the change in temperature worldwide and imbibes the regular pattern of climate to change :

   Water vapor. The most abundant greenhouse gas, but importantly, it acts as a feedback to the climate. Water vapor increases as the Earth's atmosphere warms, but so does the possibility of clouds and precipitation, making these some of the most important feedback mechanisms to the greenhouse effect.

   Carbon dioxide (CO2). A minor but very important component of the atmosphere, carbon dioxide is released through natural processes such as respiration and volcano eruptions and through human activities such as deforestation, land use changes, and burning fossil fuels. Humans have increased atmospheric CO2 concentration by a third since the Industrial Revolution began. This is the most important long-lived "forcing" of climate change.

   Methane. A hydrocarbon gas produced both through natural sources and human activities, including the decomposition of wastes in landfills, agriculture, and especially rice cultivation, as well as ruminant digestion and manure management associated with domestic livestock. On a molecule-for-molecule basis, methane is a far more active greenhouse gas than carbon dioxide, but also one which is much less abundant in the atmosphere.

   Nitrous oxide. A powerful greenhouse gas produced by soil cultivation practices, especially the use of commercial and organic fertilizers, fossil fuel combustion, nitric acid production, and biomass burning.
