Did You Know

What is Lightning?Lightning is a powerful electric spark that happens during a storm when the positive and negative charges in the atmosphere come together very quickly.

What causes Thunder?
Thunder is the loud sound you hear after a flash of lightning because the air around the lightning bolt quickly expands and creates a booming noise.

Where does lightning strike?
Lightning can strike different objects, depending on what attracts it the most. Tall objects, like trees, buildings, and even people, are more likely to be struck because they are closer to the cloud. Lightning can also strike the ground directly. When lightning hits an object or the ground, it discharges its electrical energy, resulting in a bright flash of light and a thunder sound.

What causes Lightning?
The process of lightning formation is complex and not fully understood. Scientists believe that the initial stage involves graupel, small hail particles, collecting supercooled liquid droplets, and gaining opposite electrical charges when they collide with smaller ice particles. The ice particles rise faster than the graupel due to updrafts, causing the charge on the ice particles to separate from the charge on the graupel. Laboratory studies indicate that graupel gains a positive charge at temperatures slightly below freezing, while it gains a negative charge at colder temperatures higher in the storm. The main charge regions in thunderstorms are typically caused by a negative charge on the graupel in the middle of the storm and a positive charge on ice particles in the upper part. However, there can also be a small positive charge region below the main negative charge region, formed by ice particles colliding with negative graupel in the lower region. A conceptual model developed by scientists illustrates the distribution of electrical charges in thunderstorms.

According to the NWS, thunderstorms are characterized by the presence of lightning, thunder, and convective activity. They often occur in warm and humid environments, where unstable atmospheric conditions promote the rapid upward movement of air, leading to the formation of towering cumulonimbus clouds. These storms can generate intense winds, heavy rain, hail, and tornadoes, posing hazards to life and property.

Understanding thunderstorms is essential for a variety of reasons. First and foremost, knowing the behavior and development patterns of thunderstorms allows forecasters to issue timely and accurate warnings, giving individuals and communities valuable time to prepare and take appropriate action. The NWS employs sophisticated radar systems, satellite imagery, and weather models to monitor and predict thunderstorm activity, enabling them to issue severe thunderstorm watches and warnings.
