What events ARE associated with El Niño?
Indonesian, Australia, and countries in the Western Pacific Warm Pool experience below average precipitation and drought. Fisheries off the coast of Peru fail due to a lack of nutrients from upwelling waters. The Atlantic basin experiences a below average number of hurricanes.
Why do more storms occur in Florida, Alabama, Mississippi, Louisiana, and Georgia?
Maritime tropical air masses that contain warm, moist air move to land from the Gulf of Mexico and Atlantic Ocean. Convective lifting over the hotter land surfaces lifts the warm humid air forcing it to cool producing thunderstorms.

The freezing level in the atmosphere is at a higher altitude within the thunderstorm and hail melts before reaching the ground.
