Microburst

A microburst is a localized column of sinking air (downdraft) within a thunderstorm that produces damaging winds at the surface. These intense downdrafts are often associated with heavy precipitation, but can also occur with virga (precipitation that evaporates before reaching the ground) or dry thunderstorms. They typically have a diameter of less than 2.5 miles and can generate winds comparable to or exceeding those of a weak tornado. Microbursts are categorized into wet microbursts, which contain significant rainfall, and dry microbursts, which contain little or no rain. These phenomena pose significant hazards, including damage to property, disruptions to transportation, and safety risks to outdoor activities.

Microburst meaning with examples

• A sudden, violent microburst struck the airport, causing significant delays and diversions. The intense downdraft and high winds ripped off sections of the roof of a hanger and blew debris across the runways, making conditions too dangerous for landings or takeoffs. Passengers anxiously waited for the storm to subside.
• The weather report warned of potential for severe thunderstorms, including the possibility of microbursts. Local residents secured their outdoor furniture and prepared for heavy rainfall and gusty winds. Power companies mobilized crews to prepare for possible outages caused by downed power lines.
• During the summer, the desert landscape of the Southwest often experiences dry microbursts, which can create dust storms and drastically reduce visibility. These events can create dangerous driving conditions and challenge aviation activities, sometimes creating whiteout conditions that are impossible to navigate.
• Emergency responders assessed the damage following the microburst that ripped through the town. Trees were uprooted, power lines were down, and several homes had sustained damage. Rescue workers went door-to-door to ensure the safety of all residents.
