Lost wave parameters in Code Table 4.2 during Fast Track 2019-1

[sebvi]

Details

In December 2018, ECMWF (myself) requested several wave parameters to be included in FT2019-1. The parameters were all accepted but it seems the secretariat at the time truncated the proposal forgot to include some of the parameters. The final Report sent on the 15th January 2019 does not contain some of the parameters. My guess is that the table in which the parameters were listed spun 2 pages and the person responsible to collect all the proposals into the final report did not realised only the first page was copied.....

I am attaching the original proposal and the final report of the FT2019-1 where one can't see the missing parameters. Here is the list of parameters with their new proposed code (starting at 92 to not clash with the parameters proposed in #172 )

code	Name	Units	comments
87	Wave induced mean sea level correction	m	Non-linear wave-wave interaction induced mean sea level change
88	Spectral width index	numeric	This index based on 2d spectra widths, both in direction and in frequency is needed to determine the probability of the presence of freak waves
89	Number of events in freak waves statistics	numeric	To determine the freak wave statistics, an estimate of the number of waves they represent is needed
90	U-component of surface momentum flux into ocean	N m-2	U-component of the momentum flux that drives the ocean circulation
91	V-component of surface momentum flux into ocean	N m-2	V-component of the momentum flux that drives the ocean circulation
92	Wave turbulent energy flux into ocean	W m-2	Flux of turbulent kinetic energy to the upper

Would it be possible to include these in the next fast track with new codes since new parameters were proposed since then?

@sebvi will work on

[sebvi]

updated list with newly proposed code. I made sure these codes do not clash with #172 currently under review as well.

branch is ready and will be updated asap. @marijanacrepulja and @amilan17 will check

[amilan17]

@sebvi why do the new codes begin at 92 instead of 74?

[sebvi]

because 74-91 entries were used in #172 . But in the meantime, we have withdrawn some of these entries so I need to update #172 and this issue accordingly.

[marijanacrepulja]

@amilan17 I have reviewed the branch and it looks good, could you please double check and move to "Ready for FT approval procedure" Many thanks.

renumbered the parameters to be aligned with #172

@amilan17 check consistency, codes 74-86 are used by issue #172
