CSP - Request for Collaborative Science Program (CSP) Funding - 24th WISE Meeting, Victoria, BC (Canada), 14-18 May 2017
Abstract
The attention of research and a lot of economy activity are presently put in the arctic zone. At the same time the most recent applications and extensions of the global coupled models show once more the relevant role of wind waves in shaping the local environment." The key point is that, besides the obvious role of wind waves in breaking and acting on the ice border zone in the arctic, sea wave"s have a direct role in modulating all the exchanges that take place at the sea surface between the ocean and the atmosphere. Only r"ecently a stronger attention has been given to the importance of these transfers for the long term forecast and climatic prediction,"" the fluxes havingbeen parameterized for a long while as a coefficient times U102. While the wind is obviouslyimportant, the key e""lement for a correct quantification of these transfers is the sea state, i.e. the steepness of the wind waves, their directional res""olution, if breakers (mainly white-capping) are present, etc.WISE is the most consolidated conference on wind waves, with focus" both on basic physics and on practical modeling. The conference regularly groups together the best world experts for a presentation" of the latest results, a discussion of the present situation and of the best way ahead.The present obvious tendency of the worl""d meteorological centres to extend their forecast range first in a deterministic manner to 15 days, then, although with a more ensem""ble, hence probabilistic or of the general pattern, based approach, to a monthly and seasonal forecast and further implies that the"" coupling between ocean and atmosphere is going to be the crucial aspect of any forecast. In turn this coupling, in terms of the exc""hanges of energy, gases, heat, humidity, momentum, matter is strongly modulated by wind waves. This aspect is more and more consider""ed in our community.On a more immediate application aspect much attention has been devoted and results achieved on freak waves,"" i.e. the possibility of particularly large, generally unexpected, waves during a storm. Recent results, also reported at the 2016 W""ISE meeting, show that the capability of forecasting these waves, although always in a probabilistic way, depends both on a better u"nderstanding of the physics of the storm and of the conditions that favour the appearance of these large waves. Progresses have been" done in both directions, showing for the first time the origin of the famous Draupner wave on January 1, 1995. These lines of resea"rch are further pursued for a full understanding of the physics behind and a better definition of the encounter probability and of its more correct evaluation according to the local situation.WISE meeting and GroupThe meeting is organized in an extremely i"nformal way, with extended lectures open to direct and immediate discussion, alternated with not too short coffee breaks to give the"" participants the possibility of interaction and extended discussion. The meeting is organized in 4 ~ days, starting on a Sunday aft"ernoon with an ice-breaker and carrying on for four full days till Thursday night. We want extensive discussion on the various sub"jects we deal with. The lectures are organized per subjects (e.g., physics, numerics, modeling, open sea performance, shallow water"" and coastal applications, etc.), allowing each lecturer 30 minutes, typically split as 20 minutes presentation and10 minute discus"sion. Every three lectures we have one half an hour coffee-break to favour directpersonal interactions.Being extremely informal" is one of the characteristics of the WISE meeting, the participation being based on half a page abstract for those who wish to give"" a lecture or a single notice for those who want only to attend. Typically we have between 30 and 35 lectures. Half a day, usually T""uesday afternoon, is devoted to an organized field trip to explore an area of interest for the meeting. The trip is a long moment of" open continuous interaction amo
