Short summary

Weather systems that cause floods in the Waitaki River (New Zealand) are investigated by tracing the origin and pathway of "parcels" of air associated with heavy rain. Two weather patterns are found, one causing slow moving rain systems from a sub-tropical origin; the second involving fast-moving westerly airflow. Both are strongly related to a single monthly pattern of atmospheric circulation. This is a promising new insight relevant for ongoing research on prediction of Waitaki river flow.
