JRA wind forcing #3

Closed adele-morrison closed 3 years ago

adele-morrison commented 3 years ago

Done:

A notebook showing how the easterly perturbations were set up.

To do:

It would be nice to add a plot of the zonal average 10m control and perturbed zonal wind speed to this.

adele-morrison commented 3 years ago

The notebook for this is here: https://github.com/adele157/easterlies-collaborative-project/blob/master/notebooks/forcing_perturbation/JRA_wind_perturbation_setup.ipynb

[Question: Is this the best way to link code to issues?]

adele-morrison commented 3 years ago

As suggested by Matt here, add wind speed vector plots to this JRA wind analysis (From Matt: "I say a zoom as these wind vectors get terribly messy to plot over any large domain. Shown in CTRL and then the differenced vectors separately.")

julia-neme commented 3 years ago

Something like this @matthew-england-unsw ? This is wind speed and normalized wind vectors for CTRL (left), UP - CTRL (center) and DOWN - CTRL (right). In this region the dominant difference seems to be in the meridional component of the winds. Should I try other regions of interest?

Looks great @julia-neme , but I also have a few suggestions / questions:

I assume the wind speed shading is wrong for the "DOWN" case? Looks to be identical to the UP case? i.e. +ve definite?
Can you 'white-out' all the land values? I know I should be able to do that in my mind but I still find it distracting.... :-)
Can you increase the size of the arrowheads throughout? Thanks!

matthew-england-unsw commented 3 years ago

And yes, I assume this would also be useful in other regions that we're interested in? Thanks heaps for putting this together!

julia-neme commented 3 years ago

Edited the figures, easy to replicate for other regions!

matthew-england-unsw commented 3 years ago

Ahhhh LOOKS BEAUTIFUL now....!! Thanks for sorting @julia-neme These make the wind anomalies super clear and probably will help unravel the processes at play in any of these 'surprising response' sectors.
