Analisi geografico-statistica dei campi di vento nella baia di Enoshima, Giappone.

The Olympic Games are a global phenomenon, that leaves a mark in the host countries and its cities. From the 80's onwards, the Olympics have started to involve more athletes, sports, spectators, media and sponsors; consequently, the expectations around the organization of the whole event have increased as well. Nowadays staging the Olympic Games represents a long and expensive commitment for the host country, and its impact on its cities, is a matter of continuing debate and controversy. With this research, we aim at analysing the “period of preparation “of the Olympic Games. In particular, the focus of this project is on the “Olympic Weather Support System” and the wind forecasting for the sailing events. The design of the “Olympic Weather Support System” is a crucial step for a successful organisation of the Games, given the wide variety of venues, events and group involved. Then, I'll present the methodology used in this study for a geographical and statistical analysis of the wind fields in the Enoshima bay, where the sailing competition will take place during the Tokyo 2020 Olympic Games. This method is based on the integrated assessment of meteorological data measured on the ground, meteorological data measured at sea during the training activities and the results of the CALMET model in hindcasting over a limited scale. The results obtained by the above analysis are then integrated into a graphical representation that provides to coaches and athletes the main strategic directions of the race course in a simple and easy-to-use way In the last chapter are illustrated the results of the statistical analysis, based on three indices, the graphical representation through the GIS map, and the final version of the “Call Book”.
