Which storm system is characterized by low pressure and strong winds?

The correct choice is a tropical cyclone, which encompasses a range of storm systems characterized by low pressure, strong winds, and organized convection. Tropical cyclones develop over warm ocean waters and can intensify into hurricanes, which are one specific type of tropical cyclone categorized by their wind speeds.

Tropical cyclones exhibit a definitive low-pressure core that allows for the swirling of winds around them, often leading to sustained winds exceeding 74 miles per hour in the case of hurricanes. This low pressure contrasts with other storm systems where low-pressure characteristics may not be as pronounced or are associated with different types of weather phenomena.

Furthermore, while hurricanes are a type of tropical cyclone, the term "tropical cyclone" includes a broader range of storm systems, including subtropical storms and tropical depressions. This makes the term more encompassing for the characteristics specified in the question.

Other options, such as storm surge and cold fronts, either do not specifically denote a storm system characterized by low pressure and strong winds or refer to phenomena that result from different atmospheric dynamics. For instance, a storm surge is an increase in water level due to a storm's winds and pressure, but it doesn't directly embody the characteristics of low pressure and strong winds as a storm system itself.
