A new tracking method for precipitation cells which is able to detect precipitation cells in Line-shaped rainbands using high-resolution radar (XRAIN) is developed. This method is applied for Line-shaped rainband on September 2015 and quantify the spatiotemporal characteristics of these cells. Results showed that precipitation cells with a lifespan of more than 20 minutes occur approximately every 10 minutes, exist at intervals of about 10 km, and move northward at speeds of 15 to 25 m/s. About 70% of the cells disappear within 20 to 30 minutes, while the rest continue to develop. This study provides a method for quantifying the spatial characteristics of precipitation cells in Line-shaped rainbands, offering statistical insight into their physical structure.
