What kind of weather characterizes a low pressure system?

A low-pressure system is typically associated with rising air, which leads to the formation of clouds and precipitation. As the air ascends, it cools, which can cause moisture within the air to condense into clouds and precipitation. This process creates an environment that is often warm and wet, as warm air can hold more moisture.

The presence of a low-pressure system is commonly linked to stormy weather, including rain and sometimes thunderstorms. In summer, this can manifest as warmer and more humid conditions, while in winter, it may be associated with various forms of precipitation, including rain and snow, depending on the temperature. Thus, the characteristics of a low-pressure system lead to the conclusion that it is primarily warm and wet, making it the correct choice.
