Organized lines of precipitation, frequently occur in Melbourne and the surrounding region, and are often convective in nature. Days when these features occur make up the vast majority of the most extreme rainfall days in the last ~15 years. However, they often only traverse a local region, and may only occur over a period of a few hours, so consequently often make up a fraction of the rain that falls on those extreme days. Daily and multi-day extremes are more commonly associated with large scale and longer duration rainfall events, but flash flooding is often associated with more intense rainfall over a shorter duration. This project will explore the characteristics of the linear systems (size, orientation, propagation, etc.) that lead to the most extreme events.
