  The gulf's warm sea surface temperatures can feed powerful, deadly, and destructive Atlantic hurricanes such as Hurricane Katrina in 2005. In the open Atlantic, a hurricane will draw up cool water from the depths, making it less likely that further hurricanes will follow (warm water being one of the preconditions necessary for their formation). However, the gulf is shallower; when a hurricane passes over, the water temperature may drop, but it soon rebounds enough to support another tropical cyclone. From 1970 to 2020, surface temperatures warmed at about twice the rate observed for the global ocean surface.
  
  Moisture from the Gulf of Mexico is a primary factor for the development of tornadoes and other severe weather in Tornado Alley, a term used to describe an area of the United States that is one of the most tornado-prone areas in the world. Dry air from the Rocky Mountains converges with Gulf moisture in the area, which produces storms and supercells that produce some of the most violent tornadoes in the world. A study published in the Journal of Climate by Dongmin Kim, Sang-Ki Lee, and Hosmay Lopez, found that the Madden–Julian oscillation strengthens the North American low-level jet, which increases the flow of Gulf moisture and atmospheric instability into the Central United States, furthering tornadogenesis in the region.
