Seasonal outlook providers note the cooler than average sea-surface temperatures (SSTs) in the tropical Atlantic as a key factor for a quiet season.
The El Niño Southern Oscillation (ENSO) phenomenon is signaled by sea-surface temperatures (SSTs) in the tropical East Pacific, with warm “El Niño” phases and cold “La Niña” phases. The large-scale circulations associated with El Niño enhance wind shear (changing wind speed with height) in the tropical Atlantic. The enhanced wind shear disrupts tropical cyclone development, generally resulting in fewer tropical cyclones in the Atlantic Basin. The suppressing effects of El Niño are found to be strongest in the deep tropics (1) and for African “Cape Verde” type storms.
As illustrated in the figure below, the historical proportion between basin counts and landfalls has been very volatile on an annual basis. There is only a weak correlation between hurricane counts in the Atlantic Basin and the number of U.S. landfalls. The statistical significance is a subject of some debate in the scientific community.
