Hybrid model as a limited area model

Make Snr a limited area model

limited area model around the jet stream

Advantages compared to current LAMs

  • Faster: global and LAM can be run concurrently
  • The higher resolution LAM (Snr) can influence global model (Jnr)

Where is might be used

  • Better resolution of jet stream.
    • Adam Scaife believes that signal-to-noise paradox may be solved by better resolution of jet-stream
  • Himalayas and Indian Monsoon
    • If North Atlantic is Snr 1, this could be Snr 2.
