isolated thunderstorm

Isolated thunderstorms, sometimes called air-mass or local thunderstorms, typically form in environments with light winds and abundant moisture. They are primarily vertical in structure and are relatively short-lived, usually lasting about an hour. These storms are composed of one or more convective cells, each with a life cycle involving updrafts and downdrafts. Solar heating often triggers these storms, leading to their occurrence in the late afternoon or early evening. While generally not producing violent weather at the ground, they can sometimes generate intense downdrafts known as microbursts or macrobursts, which pose a hazard to aircraft.123
