What is VATB in meteorology?

VATB stands for "Vortex Advisory Text Bulletin" in meteorology. It is a short-form report that communicates specific information about weather conditions, typically related to severe weather systems like tropical cyclones. The purpose of the VATB is to provide timely updates and concise information that can be easily disseminated among meteorologists and emergency management teams.

The nature of a VATB allows for quick communication of critical weather data that may require immediate attention or action, making it essential for real-time decision-making in meteorological services. This short-form weather report is focused and straightforward, which distinguishes it from other options listed in the question, such as long-term forecasting, types of satellite imagery, or tools designed for climate change assessment, which have different objectives and formats.
