Identifying cold air lake locations based on Meiji-Era farmland distribution

Abstract

Air temperature observations by bicycle in the spring were conducted to ascertain whether areas that were not cultivated with mulberry fields or tea plantations during the Meiji period coincided with locations where cold air lakes developed. The results demonstrated a lot of overlap between areas where tree plantations were avoided and locations prone to cold air lake formation. The depression where cold air currents tend to accumulate are susceptible to frost damage. This suggests that ancestors likely utilized land in a way that reflected this knowledge. These findings indicate the potential for inferring microclimate characteristics from past land use patterns.
