DEVELOPING THE CLIMATIC SUB-ZONES FROM THE CLIMATE ZONES OF VIET NAM

Abstract

This article presents the result of developing the climatic sub-zones from the climate zones of Viet Nam (7 climate zones), the geological map at 1:1000000 scale. The observed dataset updated to 2014 from 150 stations was used in this study. Firtstly, the criteria of developing two main climatic parts and 7 climate zones of Viet Nam based on the criteria of Nguyen Duc Ngu, Nguyen Trong Hieu (2004). There is no change in border line of two main climatic parts between the new and previous result published these authors in 2004. However, the clear change is in the new map of seven climate zones compared with the previous map. This change is the border line between the South Central and the South in the new map, that most of Binh Thuan province is defined in the South. Totally, the seven new climate zones were divided into 46 climatic sub-zones, including 39 sub-zones on land and 7 sub-zones over the sea and islands. This result can be used to develop plans, strategies for socio-economic development, natural disaster prevention for localities, especially agricultural production.
