The inter-relationship between wind direction and wind speed for 5 meteorological stations across Assam, India: A case study.

Several studies have reported that wind direction and speed prevailing at a place plays a significant role in the sediment re-suspension and bacteria deposition in the water bodies located in its vicinity. Through this paper, an attempt has been made to explore the pattern of wind direction and wind speed; the inter-relationships between them in 5 Meteorological stations across Assam, India, selecting one from each zone, using both linear and circular statistical tools. Also, a season-wise comparison of the stations with respect to the wind speed and direction has been carried out using non-parametric techniques. That the wind in Assam, on average, has been found to emanate from north-east direction during both morning and evening and the association between wind speed and direction for winter season is non-significant for all the places, constitute two important findings of the study.
