BW Topo figures document

Atmospheric river similarity plot

What does this figure need to do?

  • Motivate latitudinal extent and aspect ratio of wave
  • Showcase moisture transport properties of wave for use in dynamical core intercomparisons
  • Precipitation patterns

Evolution:

5 days of MSLP in NE60

What does this figure need to do?

  • Establishes that until day 5 it is nonlinear but well behaved (lead in to convergence)
  • Showcases evolving wave in relation to location of topography

Fields:

  • MSLP
  • PRECL
  • Precipitable water

Times: (day 2?) day 3, day 4, day 5, (day 6)

Code

Possible evolution plot centered on the mountain at e.g. 850hPa, this might be valuable to contrast dry with moist!

Evolution of precipitation over mountain

Difference between PRECL in nominal 30km grid with second and without.

  • Potential lead-in to close-up comparison of structure over the mountain.
  • Hypothesis: structural characteristics of precipitation at hitting time on hill

Fields:

  • Omega Time: day 5.

Moist/dry comparison

  • Showcases difference between dry and moist cases (e.g. why does the addition of moisture add something to this case)
  • Closeup on ω\omega over mountain? Think more about this

model intercomparison of omega evolution over the mountain lon height

minimum PSL showing convergence and clustering in moist/dry case.

  • shows that there is clustered agreement at high resolution in moist case, and standard presumed "convergence" in dry case.

Check whether these plots look as compelling when you just look at the region over the mountain

Quantitative comparison of over-mountain evolution at 850hPa (downsampled from highest resolution)

What does this show?

Possible precipitation histogram

  • Focus on time of hitting mountain, area directly over mountain.

eddy kinetic energy plot: convergence

Dynamical core comparison:

Closeup on evolution of precipitation in nominal 30km case over the mountain

Vertically averaged omega for showcasing physics-dynamics coupling strategy

Still unsure of gravity wave propagation.

FV3 outlier.
