Trend analysis and prediction of temperature change in the continental, Thailand

Diurnal Temperature Range (DTR) is one of global warming indicator which using only daily minimum temperature (TMin) and maximum (TMax) for calculation. The study aims 1) to analyse trend TMax, TMin DTR over the early period 21st century (1987 - 2020) 2) forecast mid late (2021 2040 2041-2100) MIROC5 (rcp85) model, cooperated with EQM Statistical downscaling method. TMin, trends all periods were investigated by Mann Kendall Trend Test Sen?s slope, then presented in form spatial maps. most TMax season regions tended be increasing from year large changing Northern Northeast region especially Winter, except last had a Summer. However, quietly fluctuated decreasing Eastern Southern part, but become increase period. A usually occurred Winter Rainy season. expanding leading decreased first second period, however, rate leaded It good signal heat transfer performance can help earth cooling night time.
