When might a meteorologist use both a regional weather map and a global weather map when it comes to making their predictions?

google is the first place to try, when all you have is a general question. Then tell us some of your ideas, and we maybe can help focus the discussion. But don't expect us to do your whole assignment, even including the research!
I'm not expecting anyone to do my assignment for me. This isn't even 5% of what I need for my assignment, I just need to know this in order to answer a question. I've tried Google but I found nothing that was useful. I just need help with this question, that's it.
Read lots. You should get some ideas here:

Another thing to try is to contact a meteorologist or two or three and see what they think about this topic. Here are two on social media who could help:
