Investigation of Temperature Variations in Kozhikode District, Kerala

Abstract

Kerala is situated on the Western Ghats' southern edge. Kerala has a topography that is asymmetrical. Its landform is characterized by steep slopes and rolling, quiet hills. Kerala has been experiencing temperature rise, irregular monsoons, and water scarcity for the past few years. The present study includes an investigation of temperature variations in the Kozhikode district, Kerala by examining the Maximum, Minimum, and Average Temperature in annual, seasonal, and monthly variations by time series of meteorological stations in the Kozhikode district. Gridded data of temperature prepared by the Indian Meteorological Department (IMD) and Centre for Water Resources Development and Management (CWRDM) for the Kozhikode region have been used in the study. The temperature data is collected from three meteorological stations in the Kozhikode district. The variation of temperature was analyzed by linear regression method. The statistical significance of the trend can be tested by a non-parametric test, such as the Mann-Kendall Trend Test.
