Events of the calm winds are increasing throughout the years. The wind intensity has decreased from the year 1978 to the year 2007 and increased in the year 2008-2019. The highest wind events had decreased in the year 1978 to the year 1998 and the year 2008 to the year 2019, but increased in the year 1998- the year 2007. The overall frequency of wind events is decreasing. For IInd half-year, East direction winds were dominantly in the year 1978-1987 after that West direction winds were dominantly and NE wind events decreased. Events of the calm winds are increasing throughout the year. The wind intensity has decreased from the year 1978 to the year 2007 and increased in the year 2008-2019. The highest wind events had decreased throughout the years from the year 1978 to the year 2019. The wind events in the year 2008-2019 have increased. The wind event direction was variable between NE to WSW from the year 1978 to 2019. e) Precipitation data for the year 1978-2019 Based on data analysis prepared half-yearly precipitation data with total average precipitation data tenyears’ period and for the year 1978 to the year 2019.
