Climate variability and models

World-wide, there has been increasing interest in the operational analysis of mesoscale ocean dynamics, which appear to hold the key for a correct description and prediction of ocean system behaviour (e.g. EuroGOOS goals). However, due to the three dimensional characteristics of the underlying phenomena, the characterisation of mesoscale ocean processes for numerical modelling and prediction purposes poses formidable challenges. This stems from the fact that the spatial and time scales of the phenomena involved span the ranges from 10km to 300km and a few days to some months, respectively. With currently available means, it is simply impossible (mainly for cost reasons) to obtain oceanographic data with the 3D space and time resolutions required for accurate large scale, high resolution, ocean modelling in a regular operational mode. Thus the urgent need to develop advanced technological systems for cost effective, automatic ocean data acquisition that will be able to accomplish with the 4D sampling requirements.
