The Tornado Vortex Signature (TVS) is a radar-identified pattern indicating the presence of a strong, rotating updraft within a thunderstorm, often associated with the potential for tornado formation. It is a critical tool for meteorologists in issuing timely tornado warnings, as it provides a direct observation of the atmospheric conditions conducive to tornado development.

A thunderstorm is a weather phenomenon characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere, known as thunder. These storms are typically accompanied by heavy rain, strong winds, and occasionally hail, forming from cumulonimbus clouds due to atmospheric instability and moisture.

Atmospheric conditions refer to the state of the atmosphere at a specific time and place, encompassing various elements like temperature, humidity, wind, and air pressure. These conditions are crucial for understanding weather patterns, climate change, and their impacts on ecosystems and human activities.
