Every day, citizens of Florida become potential victims to the danger of lightning strikes. As the summer creeps its way onto people’s calendars, the phenomenon of lightning strikes and thunderstorms is beginning to become more frequent.
Currently, Florida holds the title of the “lightning capital” of the United States, with seven lightning deaths per year and between 200 and 250 storm hours per year. With such extreme weather conditions, citizens of Florida often wonder why the state experiences so many thunderstorms.
Located at the tip of the United States, the peninsula sits between the Gulf of Mexico and the Atlantic Ocean. Florida is home to hundreds of beaches for residents to visit and have a good time. However, moisture in the air and the shift of warm air to meet cooler air masses are driving factors for frequent thunderstorms in Florida.
Each day, as the sun beats down on land and sea, it raises air temperatures rapidly. While the sun warms the ground and the ocean at the same rate, they have different outcomes that contribute to thunderstorms. As the sun warms the ground, its rays penetrate only a few inches of soil, causing the heat to return to the atmosphere and warm the air. As density decreases with increasing temperature, a low-pressure area known as a thermal low forms. As a result, the dense air over the ocean sinks under gravity, spreading along the coastline. Ultimately, when these reactions interact, they cause significant changes in temperature and weather as moisture gets delivered to the air. While most perceive these as pleasant gusts from the shore, they are a major contributor to thunderstorms.
Florida’s beaches, high humidity, and moisture-rich air, combined with unstable atmospheric conditions, often result in air of different temperatures being in proximity to each other. Due to the high humidity and unstable air, the state experiences strong convections ideal for thunderstorm formation.
As Florida remains the Lightning Capital of the United States, it is important to be cautious of the thunderstorms. It is important to stay indoors when these occur to ensure one’s and others’ safety.
