give me an example for all of them
high-pressure system – a system created when sinking air creates warm and dry weather
low-pressure system – a system created when rising air creates damp and stormy weather
jet stream – a narrow band of strong wind in the upper atmosphere
an example of a high-pressure system is a high-pressure ridge bringing clear and sunny weather to a region
an example of a low-pressure system is a developing tropical cyclone bringing heavy rain and strong winds
an example of a jet stream is the polar jet stream influencing the movement of weather systems across North America
