Abstract

Non parametric Bernstein polynomial estimator for circular data was applied for fitting daily wind directions. Since Thrissur District of Kerala faces a special type of wind called Vruschikakkaatu in November to February season and there is a decreases of such wind speed year after year, an analysis was conducted to check whether there is variation in wind direction. The seasonwise distribution of wind directions during morning (7.25 am) and evening (2.25 pm) for the period from 1983 to 1997 and 2003 to 2017 were separately fitted. Study revealed there is no change in the seasonal distributions.
