Injury Distribution in the Tea Field by 2010 Frost Damage in Makinohara, Shizuoka

Abstract

This paper describes three investigations of the effectiveness of a frost fan in mitigating the frost damage that occurred on March 30, 2010 in tea fields in Shizuoka. The author presents a detailed map of the distribution of damage that occurred in those fields. The map indicates that the area over which the fan is effective changes with the direction of the westerly wind, and was limited to around 25%-30 % of the designed value.
