Abstract
This study aims to analyze trends of three, annual average temperature, annual average T-max, annual average T-mini, and precipitation over the last 30 years 1990-2019 in Kandahar City, the western part of Afghanistan. For the purpose of analysis, available data from Afghanistan Meteorological Department (AMD) and Power Data Access Viewer dataset were used. First, daily average temperature and precipitation data were converted to monthly average data, then converted to annual average data for statistical calculation. The linear regression equation and trend
magnitude was applied to identify the trend of temperature and precipitation. Analysis of the data demonstrated an upward trend in average temperature, average T-max, average T-mini, and downward precipitation, the most upward trend obtained in an annual average of T-mini and less upward trend in an annual average of T-max. Simultaneously, by increasing temperature, precipitation decreased which indicates dry and hot temperatures. The ongoing climate change affects various factors, especially agriculture, and socio-economics. On this basis, it is recommended that the result could serve as a key in making plans and policies for those authorities involved in the planning. Further research is needed to identify other climatic parameters for a comprehensive understanding of the current and future climatic situation of the study area.
