The accuracy of quantitative precipitation estimation (QPE) based on different Z-R matching methods is studied during the typhoon affecting Hainan Island. The traditional matching method (TMM), the probability matching method (PMM), the window probability matching method (WPMM) and the window correlation matching method (WCMM) have been tested with Doppler radar located in Haikou. The comparison shows that the QPE using the Z-R relationship obtained from PMM is the closest to the gauge-measured rainfall, followed by WPMM. The Z-R relationship estimation established on TMM and WCMM provides large overestimated rainfall in four areas of Hainan Island, whereas WPMM and PMM slightly underestimated. Proportion with absolute error less than 20% is close to 60%, and the correlation coefficient is close to 70% between estimated hourly rainfall intensity based on PMM and gauge-measured rainfall.
