Answer 1

Hello! The polar jet stream contains strong winds that moves weather around different parts of the globe. It affects the weather and temperature, because they push air masses around, and separates warm and cold air. Cold fronts formed from cold air represents represents low pressure systems, which consists of rain or other precipitation, while warm fronts represent high pressure systems and sunny weather. They play an effect on air transportation, because planes travel faster along the jet stream, but they also have to do with global warming.
