2008/08/22 CWB & NCAR Teleconference=20 summary by Eric Chiang

 

Future work :

 

1.   1. About feedback option, Eric will test typhoon = relocation=20 case to see whether feedback will help it or not. Bao Jao Chen = will  do=20 more complete    experiments on this.

 

2.   Dr. Hong will bring the results = to NCAR on=20 Sep. and feedback will be one issue to discuss on annual = meeting.

 

3.   Guo and Yating will finish the ZTD assimilation = and=20 precipitation verification on three experiments.

 

4.   On EAKF, Liu Hui and Joseph will try a new = experiment with=20 parameters which have larger diverse on each member. ( 1 hr cycle  = is=20 seriously discussion on DART team too) .

 

5.   Guo and Maxine will do the scale tuning based on = single=20 data experiments.

 

6.   Guo and Maxine will test GEN_BE with bin_type =3D = 1

 

7.   Guo and Maxine will keep work on SEPAT to get = better=20 performance with different arrangement of WRFVar such as outer=20 loop=A1Ketc.

 

8.   Eric will test WRFDA3.0.1 gen_be use WRF3.0.1 = nodata run=20 output.

 

9.   Dr. Hong will do experiments on WRF_V3.1 and one = issues on=20 Sep is finalize the configure and synchronize issues of WRFV3.0 on CWB = and NCAR.=20

 

10.              Hong will summaries the performance on typhoon = forecast of=20 this year on WRF while visiting NCAR on SEP.

 

11.              CWB will do 3h cycle experiment on Jun/2007, the = final=20 setting on experiment waiting for Guo.

 

12.              Next week discuss WRF DFI with Dr. = Huang.

 

13.              Dr. Terng and Dr. Hong will visit NCAR during = 20080909 ~=20 20080917.

 

Recently work summary :

 

1.   Dr. Bresch suggests turn on feedback option in WRF , may  = solve the=20 problem of crash on  typhoon case with  relocation = option.  =20

 

2.   Yating designed three experiments (control=A1B all data + = gps_pw=A1Ball=20 data+gps_ztd ) of WRF 5km domain,

 

1.   and compare there results, she will concentrate = on=20 hourly precipitation verification on these experiments .

 

2.   Joseph got worse score on 2007/08 experiment with new EAKF code = + 3 hr=20 cycle + Typhoon Bogus data  compare with

 

3.   3DVAR+3hr cycle+Typhoon .

 

4.   Maxine finished 7 experiments, summaries following:

 

a.   6h cycle run, cv3, no gps experiments have better score=20 overall.

 

b.   3h cycle run, cv5, with gps experiments get slightly = better score=20 overall.

 

c.   cv5 by different month and  global boundary have no = gross=20 difference.

 

5.   Maxine did several single obs tes with CV3 CV5 options.

 

6.   Both Guo and Eric  found out WPS of WRFDA3.0.1 and = WRFVAR2.2.1 give=20 different terrain height and wrfvar input.

 

        Dr. Bresch says this different due to different = real.exe=20 code and  geogrid file.
