We are planning to create a new wind and wave atlas which will include the following tables and figures:
1. Figures
* annual and seasonal wind and wave roses,
* scatter diagrams of Hm0 and different periods,
* variation of monthly mean and maximum Hm0 and wind speeds
* deep water design Hm0 and wind speeds for various return periods,
* spatial distribution charts for mean wind speed, mean significant wave height, mean spectral peak period, mean spectral period, mean spectral energy period, mean zero crossing period, and mean wave slope in seasonal and annual basis
* the wind-wave directional misalignment
* directional spreading of waves
2. Tables
* bivariate histograms of frequency of occurrence in seasonal and annual basis between wind speed and wind direction, significant wave height and zero crossing period (Tm02), significant wave height and spectral energy period (Tm-10), significant wave height and spectral period (Tm01), significant wave height and peak period, significant wave height and wave direction, and significant wave height and wind speed at locations selected,
* appropriate wave height to use to determine the depth of closure which is the wave that is exceeded on average twelve hours in a year and wave heights, periods and wind speeds with different percentiles at locations selected
Are these tables and figures enough / suitable, which of them must be provided on the atlas? or if there are any additional ones, your suggestions and opinions will greatly be appriaciated.
Best regards
Hi George,
Thank you very much for your suggestions... I will take into consideration them...
Dear Adem,
my gratulations. This is the launch of an impressing project. I appreciate your extended consideration of parameters, in particular that of the energy period and bivariate histograms.
I do not know the length of the time series of data you will have available, but I assune the order of magnitude will be decades, since return periods of parameters are included. I recommend strongly to explain in the text how they have been evaluated in order to guarantee their comparability and avoiding misuse due to lack of knowledge. Do you intend to eveluate return periods by application of GDP with threshold? If not yet I recommend to consider its additional application. That will serve also as hint for non-experienced users that return periods depends strongly on chosen EVD and chosen parameters. Finally, the consideration of the 99,9-Percentiles of the significant wave height and the spectral energy period is a valuable asset from my point of view.
Congratulations, I look forward to learn more about the product.
Dear Hanz Niemeyer,
Thank you very much for your message and valuable comments and suggestions.
We will have a 31-year hindcast dataset including various wind and wave parameters. Is your suggestion that we should include the spatial maps in different decades to see the order of magnitude (past to present).
I agree with you that we should include explanations in the text.
In the long-term extreme value analysis we think to apply GEV Type I (Gumbel) distribution using annual maxima waves. But, I also wonder application of GDP with threshold. Therefore, we can apply it.
Again, thank you very much for your valuable suggestions.
Dear Adem,
Since you will deal with a 31-year hindcast, I guess that plots and tables showing interannual and seasonal variations of wave parameters would be useful and interesting.
Best regards, I hope to see your ready atlas!
Dear Fedor,
Thank you very much for your interest and suggestion. I hope to share the results as soon as possible.
