A SIMPLIFIED UNDERSTANDING FOR CYCLONES IMPACTS ON THE GENERATED WAVE ENERGY SPECTRUM FOR COASTAL AREAS WITH DIFFERENT BOUNDARY CONDITIONS
M. A. Khalifa

Abstract:
Many studies are carried out to handle the generated wave energy due to wind blowing through the different cyclonic activities. Little of them is handle the prediction of this generated energy based on a certain cyclone with specific characteristics. In this research, it concentrates on simplifying the understanding of the main concepts of the spectral analysis of wave energy prediction through a detailed numerical modeling study. The study handles two different practical cases with different characteristics. The first one handles the generated wave energy on four selected observation points on the Egyptian northern coast under both moderate and strong cyclonic conditions for a total expected cyclonic period of 130 hours. The second case handles analyzing this energy for a closed bay area close to the southern boundary of the Atlantic Ocean in South America continent via a constant increasing in time increment effect in the cyclone development for a total time equals 24 hours. The study comes up with a group of practical conclusions for the studied cases, which may help to simplify the understanding of the effects of the cyclonic activities on the generated spectral wave energy for coastal areas with different boundary conditions. Therefore, it may be a step forward towards better practical applications in both engineering and research fields.

Keywords and phrases: wind cyclones, cyclones impact, generated energy from wind, wave spectrum, coastal areas boundary conditions.
