Discontinuity of Diurnal Temperature Range Along Elevated Regions

Low-clouds and fog moderate the diurnal temperature range (DTR) through radiative effects. Consequently, frequent foggy events make montane cloud forests (MCFs) stable unique. However, high-resolution observations in forest understory are rare. To investigate DTR variation elevations, we surveyed Central Cross-Island Highway central Taiwan along altitude of 0–3,000 m across both non-cloud MCFs. The results from paired weather stations revealed that increases significantly with open fields but not forest's understory. Furthermore, continuous indicate smaller DTRs were found field sites MCF compared those low- high-altitude sites. discontinuity highlights indispensability for mountain ecosystem. Further simulating integrative effect climate land-use change on is crucial ecoclimate mountainous regions.
