Introduction Variations in the global climate has been phenomena observed in the past as well as in the present, but now it has been treated as a serious issue by people all around the world from scientists to policy makers and layman everyone speak about the climate change in the current century. The variations in the global temperate have been keenly watched over especially in the last few decades. According to the Fifth Assessment report of IPCC (2013) the global average temperature has increased by 0.85˚ since 1880 to 2013.But the change in the climate varies from place to place and the need for policies to adapt or the urgency to adapt differs from one place to another. Various researches have been going on all over the world to assess…show more content…
The rate of increase in the temperature has been noted to be happening in a fast pace. As per the global warming predictions made in the 1980s, the global temperature in the last three decades has increased by 0.2˚ (Hansen J, 2006). It has been noted that the last three decades, which belongs to the 20th century was the hottest in the last 1400 years (IPCC 2013).When we look into the temperature change in India in relation to the global trend of the increasing temperature, many studies suggest that India is following the global trend. India is known for its diversity in various characteristics even in terms of weather patterns it has different nature at different localities. According to Koppens’ classification it has been concluded that the whole of the peninsular India is following the Tropical Savannah climate while the west coast is a Tropical Rain Forest. The most important events of weather which affects India area Heat Wave, Cold Wave, Snowfall, Floods, Droughts, Cyclones and Fog (Dash S K, 2007).The frequency of these events lead to the major changes in the climatic pattern of a region. The above mentioned events have greater impact all over the country yet the worst affected and the most significant regions are the coastal regions…show more content…
This unequal heating produces difference in pressure in different parts of the earth and when the atmosphere tries to equalize the pressure by shifting the air masses from high pressure to low pressure wind is developed. So the measurement of the wind speed and also knowing its direction plays a critical role in the prediction of the weather. The wind speed is one of the primary factors which drive the evaporation process on the earth. The wind speed in our study area is showing a steep decreasing trend over the 40 years. The data suggests that the wind speed was high during the 1970 's when it was recorded 16km/h on an average during a year, during the 1980 's the mean annual wind speed gradually went down then in the early 90 's it mean annual wind speed of the region saw an increase and again it started declining in the later in 90 's and went down to the worse in 2000 's where on an average it was recorded to be 5.6 km/h. Based on the summary of the various studies conducted all over the world on the changing wind speeds it has been found that there is a decline in surface wind speed over many other parts of the world such as Australia, Africa, East Asia, South East and Central Asia, North, Central and South America and Germany. While the mean annual variability in the wind speed has been analyzed based on the data obtained from nearly 58 stations in India, it has been found that the data is showing a
