Researchers found that our basic understanding of "low pressure systems" has been flawed for more than 90 years.
Scientists from the University of Manchester contradicted traditional understanding of how low pressure systems evolve.
The Norwegian model in use since the 1920s is that when a storm occludes, it will automatically weaken.
Writing in the journal Bulletin of the American Meteorological Society, they found that the Great Storm of October 1987 and the Burns’ Day storm of January 1990 did not fit the model.
Dr David Schultz, from the university’s School of Earth, Atmospheric and Environmental Sciences, who led the study, said that while both were occluded (evolving), but still deadly.
