ENSO and North Atlantic Hurricanes
Atlantic Hurricane Tracks
Hurricane tracks can also be influenced by ENSO. Figure 6 shows the tracks
of hurricanes in El Niño and La Niña years. Figure 7 show the
density of tracks in for the same years. The Atlantic was divided
in small boxes of latitude and longitude and we counted how many times
the hurricane tracks fell in each box. The larger number of hits is shown
in Figure 7 by colors in different shades of red and the smaller number
of hits (minimum one hit) is shown in different blue shades. By examiniming
both Figures, one notices the larger number of Hurricanes in La Niña
years, also more hurricanes cross the Caribbean and more
hurricanes make landfall in the U.S. in La Niña than in El Niño
years (Gray, 1984).
