The area of interest covers an inner part of street canyon and adjacent intersection. Time-averaged momentum flux were divided into particular quadrants using Quadrant analysis method. Comparison between flux events and skewness provides some insight into the spatial distribution of strong intermittent tendency and explain better the spatially local dominance of sweep and ejection.
