Assessing the difference in the temperature trend in the context of climate change in Bac Giang province

Abstract

Bac Giang is a province in the northern midland and mountainous region of Vietnam. Bac Giang has many potentials and advantages in terms of natural conditions and human resources for economic development. However, climate change has been having a great impact on the socio-economic development of the province. The study applied the correlation assessment method and regression analysis to process temperature data at 4 meteorological stations: Bac Giang, Hiep Hoa, Son Dong, and Luc Ngan. The results demonstrate that in 44 years (1970 - 2014) the trend of change in average temperature is from 0.012 oC\year to 0.018 oC\year. On the other hand, the changing trend of the annual absolute maximum temperature is common at a higher level, from 0.028 oC\year to 0.032 oC\year. The variability of extreme temperature values is much broader than that of the average temperature. The trend of temperature variation (average temperature, annual absolute maximum temperature) is highest in the eastern territory of the province, in mountainous districts including Son Dong, Luc Ngan, and lowest in the western lowland areas namely Hiep Hoa district. The research results will be the assisting tool for management agencies to find solutions to develop socio-economic adaptation to climate change.
