Draft:List of weather events considered the most significant

This is a list of weather events considered to be the most significant in which reliable sources, surveys or academic assessments consider criteria such as, but not limited to, how impactful the event was, how deadly the event was, the impact on science, or other specific criteria. These events may be referred to as most important, most iconic, most signficiant, or the worst—but they are all considered key events in the history of meteorology. For an event to be listed here, it must be cited by either one all-time assessment, two decade-based assessments, or four yearly-based assessments.
