accwa

Project Objectives

The general objective of the ACCWA project is to quantify the present and to explore the future wave climate in the Black Sea basin, with a special focus on the Romanian coastal environment.

Regional wave climate projection studies provide valuable input to regional coastal impacts and adaptation assessments, but to date, such studies have not been made for the Black Sea. Starting from the fact that, different and diverse projections of the wind climate are available, the first target is to evaluate how realistic the RCM wind fields are in the recent past for the target area. The opportunity of such evaluation is given also by the fact that in enclosed basins, as the Black Sea is, the modelled wind fields are less accurate than in open ocean due to the strong influence of the land on the marine surface wind fields (Signell et al., 2005; Rusu et al., 2014), as also due to their high variability (Efimov & Anisimov, 2011). Thus, the ensemble of the historical downscaled wind fields provided by RCMs will be compared with observations and also with several reanalysis data sets. Without this careful evaluation, the uncertainties in the projections of future wind climate regimes may also propagate in the wave projections, decreasing the degree of confidence of the results. Farther on, extended simulations with the wave model will be performed for three climate periods, of 30-year time-slice each, using the output of the chosen RCM. Slices of thirty years of data were chosen because this time interval is considered by the World Meteorological Organization (WMO) long enough to calculate an average that is not influenced by year-to-year variability, and which is also used for so called climate ‘normal’ (Arguez & Vose, 2011). These time-slices will cover the ‘present’ conditions, regarded as the ‘control’ conditions, when the simulation results will be compared with observations (altimeter and in-situ measurements), the ‘near future’ conditions that will cover the mid-21st century, and a century later into the ‘future’ conditions (the last 30-year period of the 21st century).

Validations of the climate model-derived wave fields for ‘present’ conditions will be made, and also an evaluation of how accurately the resulted wave climate fields are, compared with historical means and extremes wave records. Data assimilation (DA) methods (e.g. the method applied by Rusu, 2015) will be used to improve the significant wave height predictions, when observations are available. As a next step, two sets of simulations corresponding to the future conditions (for both the time-slices) will be made considering the new emission scenarios RCP4.5 and RCP8.5. Based on the results obtained, potential future changes in the wave climate of the Black Sea will be assessed, especially for identification of the possible trends in the sea wave climate. A particular attention will be paid to quantify the climate change effects on the severity and frequency of extreme meteorological and marine events. Estimations of the future changes of the mean and extreme values of the main wave parameters will be made.

A two-level wave modelling system will be used in the process of downscaling from the offshore towards the Romanian coastal environment. Wave climate simulations will be made at both levels. The further evaluations in the Romanian nearshore will use information from the second level that accounts better for the wave transformation in the coastal area. Based on this information, the expected coastal dynamics will be also assessed. Finally, new high resolution data archives for wind speeds, significant wave heights, mean wave periods and mean wave directions will be developed for the time-slices considered.

Project Results

The main outcomes resulting from ACCWA project will be:

1. estimation of the future changes of the mean and extreme values of the main wave parameters will be made for the entire Black Sea basin, together with their variability and long-term changes;
2. an evaluation of the expected coastal dynamics in the Romanian nearshore;
3. development of the new high resolution data archives for wind speeds, significant wave heights, mean wave periods and mean wave directions for the time slice considered;
4. projections concerning possible wind and wave energy exploitations in the Romanian coastal environment based o the simulations of the future wave climate, together with the analysis of the wind fields derived from RCM output;
5. evaluation of the changes in the marine extreme events in some key locations.
