Is it possible to built an efficient meteotsunami warning system

Proper monitoring of a meteotsunami (atmospherically induced destructive long ocean waves in a tsunami frequency band) demands non-standard meteorological and oceanographic measurements, with sampling resolution on a minute scale or even denser. That directs the problem similar to the general problem of monitoring of a tsunami, including the warning efficiency issues. Two ways are presently eligible for the development of a meteotsunami warning system: (i) monitoring of the synoptic conditions and trying to assess the characteristic atmospheric fields over the wider area, and/or (ii) monitoring of high-resolution atmospheric and oceanographic data in real-time, and rapid assessment of the probability for fulfilling a number of meteotsunami conditions (proper speed, direction, intensity and coherence of an air pressure high-resolution disturbance). The second approach can be realized through (i) a network of real-time microbarographs and pressure/coastal tide gauges, or (ii) high-resolution remote observations which can capture some of the meteotsunami early signs (e.g. strong currents by coastal HF radar). Both approaches include the development of a procedure/algorithm for detection and assessment of the atmospheric/ocean meteotsunami waves, and may include ocean numerical modelling and pre-definition of a destructive ocean waves pathways and intensity recognizable by a pattern-extracting algorithm (e.g. Self Organising Maps or similar). Adriatic meteotsunamis will be used for a description of such a network.
