low sea level with wind forcing

[flcastej]

Hi,

I am trying to simulate a coastal lagoon, (max. depth=6m, area=170 mk2 ) only forcing with real wind data. I use the Bulk_fluxes, but comparing the ROMs data with the registred data for the same period simulated, I get smaller values with ROMs. Registered data is around 0.1 m sea level fluctuations (remove tide), and ROMs data maximum is about 0.01.

I am use this options:


#define UV_ADV
#define UV_COR
#define DJ_GRADPS
#define TS_MPDATA
#define SALINITY
#define SOLVE3D
#define SPLINES
#define MASKING
#define AVERAGES
#define BULK_FLUXES
#define STATIONS
#define ATM_PRESS
#define UV_LOGDRAG
#define ANA_INITIAL

#define MY25_MIXING
#define KANTHA_CLAYSON
#define N2S2_HORAVG

I am using 16 sigma level.

RDRG == 3.0d-04 ! m/s
RDRG2 == 3.0d-03 ! nondimensional
Zob == 0.015d0 ! m
Zos == 0.02d0 ! m


Someone could advise me about what i am doing wrong or where start to look for the problem?

Thanks a lot !!!

Hi,

After a lot of test done, messages in the forum read and a bit of luck, I has resolve my problem. I dont know if it ´s the right answer, but at the moment, I get the expected results.

With bulk fluxes, using the value of BLK_ZW =1 instead usual one BLK_ZW = 10.

BLK_ZW Height (m) of surface winds measurement. Usually, recorded
! at 10 m
