What does "TS" denote in meteorological terms?

In meteorological terms, "TS" denotes a thunderstorm. Thunderstorms are significant weather phenomena characterized by the presence of lightning and thunder, typically associated with convective weather systems. They can produce various hazards, including heavy rain, strong winds, hail, and even tornadoes in some cases.

Understanding the terminology used in meteorology is crucial for effective communication among air traffic controllers and pilots, especially considering the impact thunderstorms can have on flight operations. Thunderstorms are classified into different categories, such as single-cell and multi-cell, and their intensity can vary widely, necessitating a thorough understanding of how they are denoted and categorized.

The other options refer to different weather phenomena, such as hurricanes and typhoons, which are tropical cyclones with sustained winds exceeding a certain threshold, and tornadoes, which are violently rotating columns of air in contact with the ground. Each of these weather events has its own unique characteristics and implications for aviation and meteorology, making "TS" specifically associated with thunderstorms.
