- Abstract:
-
Under the exceptional circumstances with climate and other factors, led to frequent disasters in Taiwan, and the rainfall is the mainly factors of the occurrence of major disasters. According to the Central Meteorological Bureau at 21 weather stations distributed in northern, central, south, and east regions of Taiwan, undertake the frequency analysis for the maximum rainfall in one day and maximum rainfall in one hour, to analyze five different methods of frequency analysis, such as: the normal distribution, logarithmic normal distribution, the Extreme-value type I distribution, Pearson type Ⅲ, log-Pearson type Ⅲ distribution. To obtain the different return periods (5, 10, 50 or 100 years, 200 years), the standard deviation of the minimum value, for a suitable theory of the distribution. Results showed that: whether the maximum rainfall in one day or the maximum rainfall in one hour, the Taiwan region are proposed for the distribution of Pearson type Ⅲ to estimate frequency analysis.
