Dear All,
I have run the WRF Model yearly (2010,2011, and 2012) and few years as a single run (2010-2012) using GFS data. After running real_nmm.exe,
I observed Boundary conditions and Initial conditions for Individual years 2010, 2011 and 2012 with combined year run 2010-2012.
2010: Both Initial and Boundary conditions are Same.
2011: Boundary Conditions are same but Initial conditions different
2012: Boundary Conditions are same but Initial conditions different
Now I compared the Time series of Individual years 2010, 2011 and 2012 with combined year run 2010-2012.
2010: The Wind speed values is same throughout the period.
2011: Wind speed Values are almost correlated well for every month except from Mid of April to August.
2012:Wind speed Values are almost correlated well for every month except from Mid of April to August.
I Observed there is only difference in initial conditions (rest of all are same, Input data, Boundary conditions, Parameterization schemes, same location, resolution etc). So i expected all the months of 2011 and 2012 should be differ from 2010-2012 single run. But it showed difference for few months as mentioned above. I done the similar analysis for another location, The results are same as earlier.
I am unable to understand how to explain this behaviour. I attached all the results in excel file which is in zip file.
Waiting for your Valuable Ideas,
Thanks & Regards,

In order to answer your question, I need to know the following:
Hi Frederik,
1) I used Thailand region (101.47E and 15.40N)
2) For Boundary conditions, I have used GFS data (http://nomads.ncdc.noaa.gov/cgi-bin/ncdc-ui/define-collection.pl?model_sys=gfsanl&model_name=gfsanl&grid_name=3)
3) Without spectral Nudging.
I attached namelist files for more information. I used WRF-NMM model for my work.
Thanks & Regards,
Malleswararao M
well It is interesting, I want to ask some more questions, what is the monsoonal period in the study area? Since 2011 and 2012 behave same for wind during mid april to august that seams due to some connection with weak monsoonal currents. I am not sure but let me see your data and think. Thanks for asking this question
