Historical Tropical Storm/Tropical Cyclone probability and tracks |

General Description |
|
What data/products do you use? |
Historical observations of tropical cyclone positions, intensities, sizes and other quantitative measures are readily available in six hour intervals (and sometimes more frequently) from multiple global agencies via the best track archives that comprise IBTrACS. |
When do you use this kind of dataset? |
Historical observations of tropical cyclones data are used to great extent by the O&G industry in tropical storm prone areas for all phases throughout the O&G cycle, except strictly operational tasks. These data are extremely important to assess risk of operations in these areas, frequency of occurrence, most likely track etc. Also, many other data sources do not catch the extremes in the area without these data added to the time series for the point of interest, since data often are averaged and conditions often are mostly benign.
|
What are your actual limitations and do you have a work around? |
The averaging periods of the reported maximum wind speeds in tropical cyclones varies among global agencies and must be reconciled across all record sets prior to analyses. |
Needs and expectations on EO data |
EO is used for this today in combination with modeled data.

Data quality |
The selected sources in this document are selected because they are known to have sufficient quality (after some work arounds and adaptations). In general separate indepth verification studies has to be made for each source planned to be used for analysis, and the analysis has to be repeated for each geographical area (since sources might be of sufficient quality in one area but not another). |
Data Coverage and extent |
Regional or along track. |
Example format |
netCDF and CSV |
Timeliness |
Normally needed urgently, possibly before assessing, planning, or exploring a new field. Hence the data source used for analysis needs to be frequently updated to avoid unnecessary waiting. Daily, weekly or monthly updates of data sets are sufficient, depending on the analysis required. |
Existing standards |
DNV-RP-C205, ISO-19001-1, and DNV-OS-J001 contain cautionary notes regarding the treatment of winds and waves in areas that experience tropical cyclones, such as South China Sea, West of Ireland, and Myanmar. |
