Summary:
This research aims to describe wave and selected meteorological characteristics
from in-situ data (Poseidon System - HCMR) of the Greek Seas and from the
ERA-Interim reanalysis database to extract new information and to enhance
existing knowledge. Parameters analyzed are height, period and wave direction,
wind speed and direction, air temperature and atmospheric pressure and sea
surface elevation. The two databases are collocated with 3 methods: (i) nearest
intersect; (ii) weighted distance average; and (iii) weighted distance average
of the 4 grid boxes. Trends are investigated for wave height and period, wind
speed and temperature at 2 m. Wave propagation at the coastal zone of Pinios
River (Thessaly) and sea level rise (AR5 IPCC) are simulated with the
mathematical model (MIKE 21 PMS). The most important findings are: (i) sea
surface elevation analysis provides more wave state characteristics than the
direct buoy measurements; (ii) the complex coastline and the islands effect
wave propagation; (iii) ERA-Interim can be considered representative for the
wave and meteorological state of the Greek Seas, for offshore locations; (iv)
empirical equations of the spectral / statistical wave characteristics and the
wave propagation differ for the Greek Seas; (v) sea level rise effects the
nearshore hydrodynamic conditions.
