New Orleans, the Gulf Coast and the eastern coast of the United States are affected by the Atlantic hurricane season, which runs from June 1st through November 30th each year. Texas and Florida are the most hit. Activity typically peaks from late August through September, particularly around September 10th.
Scientists have identified four parameters that influence the hurricane season in the Atlantic basin. Stratospheric quasi-biennial oscillation is the circling of winds around the Earth from east to west near the equator. These winds take approximately two years to complete a cycle. El niño southern oscillation raises water temperatures. African rainfall also plays a part in hurricane season as does West Africa's west-to-east surface pressure.
