Abstract

This study uses rainfall collected from the global online rainfall monitoring system to build a database and rainfall map for the period 2002-2022 in Thai Nguyen province. The results show that rainfall tends to be unevenly distributed across areas in Thai Nguyen province over the years and periods. In the periods 2006-2010, 2011-2015, 2016-2020, rainfall is mainly concentrated in the southwest of Thai Nguyen province in Dai Tu district; Song Cong city and Pho Yen city, most in Tam Dao mountain area. In 2021 and 2022, rainfall is mainly concentrated in the west and northwest in Dinh Hoa, Phu Luong and Dai Tu districts with the lowest rainfall of 1,170mm, the highest of 1,494 mm and an average of 1,330 mm. Rainfall is lowest in the northeast and southeast of the province in Vo Nhai and Phu Binh districts with rainfall from 1,143 mm to 1,241 mm, and an average rainfall of 1,192mm. The results of this study are a reference database for policy makers when analyzing and researching agricultural development and natural disaster prevention in Thai Nguyen province.
