Working groups

COST733 is is organised in four working groups, with the following tasks, objectives and deliverables.

During the first phase WG1 was established and divided into 3 subgroups (A), (B) and (C)

WG 1A: Inventory of weather types classifications,

WG 1B: Identification of requirements of the various applications,

WG 1C: Selection of classification methods and of applications to be used in this Action.

There was an intense exchange of information between these 3 subgroups. WG1 finished in September 2006.

	Computation of time series of weather type data using the selected methods of WG1C and a defined basic data set (e.g. ERA40) for different European regions,
	Selection of the features from the different selected methods to be combined in a new common method (based on results of WG1 and the recommendations from WG3 and WG4),
	Conception and development of the new method,
	Programming of the new method,
	Computation of time series of the new method in different European regions using the same data set,
	Corrections and updates of the new method (after exchange of results with WG3 and 4),
	Presentation and release of the weather types classification data to the other WGs and the interested scientific community.

Find or devise statistical tools for an intercomparison of weather types classification methods,

Statistical comparison/evaluation of available weather type data including the data provided by WG2,

Assessment of the statistical results,

Presentation and release of results to the other WGs and the interested scientific community,

Recommend specifications for a new (common) method (interaction with WG2).

Selection of dedicated applications (using results from WG1),

Collection/development of application software,

Performance of the selected applications using available weather type data including those provided by WG2,

Comparison of the application results with results of former methods,

Final assessment of the results and uncertainties,

Presentation and release of results to the other WGs and the interested scientific community.

Recommend specifications for a new (common) method WG2
