Abstract

Analysis of Microclimate Characteristics of Small Mountain Forest in Korea Using Weather Sensor Array

Highlights

  • Forest microclimates [temperature, relative humidity (RH), illumination, soil temperature] have unique characteristics[1] that depend on factors including slope, direction, altitude, and vegetation type

  • Is in turn affected by external environmental factors such as climate and weather.[3,4,5] Using the Automatic Weather Stations of the Meteorological Administration and Korea Forest Service, we analyzed the generated wind fields that affect the occurrence of forest fires, and the distribution was found to be highly correlated with mountain characteristics.[6]. Forest disasters are driven by weather conditions such as temperature, RH, wind speed, and geographic conditions such as topography, forest type, and structure.[7] forest disasters in mountainous terrain are closely related to microclimate, and a detailed analysis of the local meteorological conditions of these forests is required to predict and prevent forest disasters

  • Annual mean temperature (T) was highest to the south (9.8 °C) and lowest to the southeast (9.2 °C); annual mean maximum temperature (TMAX) was highest to the north (15.5 °C) and lowest to the west (13.7 °C); annual mean minimum temperature (TMIN) was highest to the west (6.4 °C) and lowest to the north (5.4 °C); annual mean RH was highest to the southeast (71.1%) and lowest to the west (67%); and annual mean LI was highest to the south (20.7 lx) and lowest to the west (3.8 lx)

Summary

Introduction

Forest microclimates [temperature, relative humidity (RH), illumination, soil temperature] have unique characteristics[1] that depend on factors including slope, direction, altitude, and vegetation type. Is in turn affected by external environmental factors such as climate and weather.[3,4,5] Using the Automatic Weather Stations of the Meteorological Administration and Korea Forest Service, we analyzed the generated wind fields that affect the occurrence of forest fires, and the distribution was found to be highly correlated with mountain characteristics.[6] Forest disasters are driven by weather conditions such as temperature, RH, wind speed, and geographic conditions such as topography, forest type, and structure.[7] forest disasters in mountainous terrain are closely related to microclimate, and a detailed analysis of the local meteorological conditions of these forests is required to predict and prevent forest disasters. Our study was conducted to understand the effects of the topographical and structural characteristics of a forest on the localized microclimate by analyzing the meteorological changes according to the direction and distance from the forest edge
