ABSTRACT

 

Natural calamities those we have much experiences have been destructing era to era are Tsunami in December 22, 2004, Aila in May 25, 2009 and recent earthquake in March 11, 2011 in Sendai, Japan, Tornados and Cyclones. Main objective of this research is to keep on eye on the motions of the Earth about the sun and its own axis and environmental conditions and so on, whether they have any role behind these calamities. Data has been taking since April 2005 after the Tsunami and that has been going on. After analyzing those data of the Zenith angle (), the rotational angle () and the temperature of the Earthfs atmosphere, it is found that the Earthfs revolutionary plane about the sun is changed. Maximum and minimum Zenith angles are always yearly changing. Similarly rotational angle and temperature are also changing. The abrupt nature of this movement may cause devastating tsunamis in the form of earthquake, cyclones and tornados in addition of abnormal solar irradiation, humidity, temperature and pressure. Recently, we have seen that origins of variation of the solar luminosity (LS) what the Earth is getting are principally the absorption by the Earth's atmosphere, different , and . Maximum LS is observed to be (0.449 } 0.004)~1026 W in the month of July in 2009 at forenoon where 88% of LS is absorbed by the air molecules. Maximum LS absorption is found to be 90% in January 2010 because of the air pollution. Another important finding of this measurement is the shape of the movement of the Earth over the year is like an Ink-pot. The variation of rate of change of temperature with Zenith angle between the summer solstice and the winter solstice is about 2.47o C/deg. The variation of solar luminosity between the summer solstice and the winter solstice is about 0.01715~1026 W. The maximum luminosity is observed to be 0.45~1026 W. Significant variations of temperature and angular momentum are observed in monsoon period. Demarcation lines of climatic change are achieved and those make cautionary signals of massive destruction.
