Identifying a Weather Event
The provided options include various statements and data points, but the one that fits the category of a weather event is option a): The hurricane season lasts from June 1 through November 30. This explicitly references a specific period during the year when hurricanes, which are intense weather systems, are most likely to develop. This contrasts with option b), which describes a climatic trend rather than a singular event.
Regarding the hurricane season, it is an annually recurring time period when most tropical cyclones are expected to develop across the northern Atlantic Ocean. This is because of the suitable environmental conditions such as warm sea surface temperatures and favorable wind patterns that prevail at this time. The knowledge of the hurricane season is vital for preparedness and risk management in regions susceptible to tropical storms and hurricanes.
