Kết quả tính toán giá trị cực trị và tính biến động của yếu tố gió tại đảo Lý Sơn

Abstract

The concept of extreme wind velocity here is understood to mean that the maximum value for a period of observation and the  analytical method, it is used to determine wind speed values ​​in the direction of any return period.

In maritime technical practice, the most used return period range from 50 years to 200 years, however, with high economic, social and historical significance, it is commonly used. 500 years, 1000 years, even 10,000 years. Seasonal characteristic values ​​as well as extreme frequency extremes, which are important for coastal design work, will greatly assist in determining the direction of play. the economic development of the island district, the planning of anchor mooring areas to avoid storms, wind power development ... This paper presents results of calculation of extreme values and fluctuations of wind elements on Ly Son Island of  National research project KC09.11 / 11-15.
