Abstract

This study proposed the quantitative precipitation estimation method using overlapped area in radar network. For this purpose, the dense rain gauges and radar network are used. As a result, we found a reflectivity bias between two radar located in different area and developed the new quantitative precipitation estimation method using the bias. Estimated radar rainfall from this method showed the apt radar rainfall estimate than the other results from conventional method at overall rainfall field.

본 연구는 레이더의 중첩관측영역을 활용한 정량적 강수량 추정방법을 제안하였다. 이를 위해 국내의 조밀한 지상우량계 관측망과 레이더 관측망의 중첩관측영역을 이용하였다. 결과적으로 중첩관측영역 내 레이더간의 계통오차를 확인하였으며, 이를 이용하여 새로운 정량적 강수량 추정방법을 개발하였다. 이 방법으로 추정된 강우강도는 기존의 정량적 강수량 추정방법보다 모든 강우강도 범위에서 강수량이 적절하게 추정되는 것으로 나타났다.
