C onclusions and S uggestions In the present synthesis of available data and analysis, it observed that the average solar radiation and precipitation pattern have decreased during the past 32 the years (the year 1988-2019). The atmospheric pressure and mean temperature have increased during the past 32 the years. Due to changes in atmospheric pressure, wind events and intensity of extreme wind events have decreased from the decade1978-1987 to the decade 2008-2019. The speed of extreme wind events decreased from 95-100km/h in the decade 1978- 1987 to 25-30 km/h in the decade 2008-2019. The wind calm events were increased from the year 1978 to 2007 but decreased in the year 2008 to 2019.The precipitation received in Ist half-year has increased concerning the total precipitation. The above interpretation, it is indicating that variation in wind flow happened due a change in atmospheric pressure. The continued variation in atmospheric pressure indicates that the thickness of atmosphere is decreasing at Kota due to present climate change. It also seems that the arid winds are moving towards Kota and increasing the temperature, decrease the precipitation with more calm winds. The change in wind flow and increase in minimum temperature may increase the probability of Hydro- meteorological disasters. It is observed that the highest winds events direction might shift towards West and South direction and causing the hot and humid weather with the decrease in precipitation. Extreme wind events have increased as well as calm wind events have increased. It is predicted that the confluence zone of the Heddle Cell and mid-latitude Cell is shifting/fluctuating towards the equator, and the confluence zone is receiving the maximum calm wind events and extreme weather conditions. It is also possible that during the Ist half-year, the Heddle Cell may move more towards the North and due to it, more precipitation received in Ist half-year and high temperature/extreme summer. The Mid-latitude cell moves towards the equator during IInd half the year, which is cold and dry, decreasing the precipitation and temperature. But the yearly impact of these winds shows a decrease in the precipitation, increase in the temperature and calm winds, variation in wind events, and frequency of extreme weather events will be increased. We can take pre-disaster mitigation measures for hazard-prone areas and identify the new prone-area. Public awareness, disaster prediction, hazard mitigation structures, and communication methods would be helpful for saving the ecosystem. R eferences R éférences R eferencias 1.
