Which term describes the changes in atmospheric pressure that affect weather patterns?

1. High pressure system

2. Thermal inversion

3. Wind shear

4. Low pressure system

The correct answer is: Low pressure system

The term that describes the changes in atmospheric pressure that affect weather patterns is low pressure system. Low pressure systems are regions where the atmospheric pressure is lower than the surrounding areas, which often leads to unsettled weather conditions, including cloud formation and precipitation. These systems are associated with rising air, which can lead to cooling and condensation, resulting in various weather phenomena such as storms and rain. Understanding low pressure systems is essential in meteorology, as they often indicate that air is converging in the lower atmosphere, promoting the development of clouds and various weather changes. The interaction between high and low pressure systems is fundamental in creating wind patterns and influencing overall weather conditions.
