This is an update to a previous blog post – Convective Storm Evolution Following Mergers between Squall Lines and Isolated Supercell Thunderstorms
Last fall, Dr. Adam French, provided WFO Raleigh with a presentation on his research that examined mergers between squall lines and isolated supercell thunderstorms. A summary of the presentation along with links to a recording of the presentation along with the power point and a PDF of the presentation are available in the original blog post.
The recently released April edition of Weather and Forecasting includes an article authored by Dr. Adam French and Dr. Matthew Parker that formally shares this research –
Observations of Mergers Between Squall Lines and Isolated Supercell Thunderstorms
The paper describes the evolving severe weather threat during the course of the squall line and supercell merger, with the details of the evolution and severe weather threat largely dependent upon the background environment. The paper provides several worthwhile conceptual models and some excellent context for radar operators to be aware of during warning operations.
