The jet stream influences global weather by doing what? A: Producing thunderstormsB: Moving weather from one place to anotherC: Producing areas of high pressureD: Producing floods

I'll assume B. Moving weather from one place to another and/or C. Producing areas of high pressure because those make the most sense and the Jetstream is a high pressured sheer or "gust" so to speak of wind and because its moving through the clouds it is assumed possible that it could move storms but severe storms are certainly caused by higher pressure.
