Which statement describes the high and low pressure systems and their affect on global climate?

High pressure systems bring storms; low pressure systems bring sunny and fair

weather.

creates low pressure systems.

High and low pressure systems do not affect the global climate.

High pressure systems bring colder temperatures from the north and south poles

resulting in precipitation.
