AB: Climate change and variability involved many aspects of the climate system and the assessment of anthropogenically-forced climate change has considerably focused on surface temperature as a primary variable. In this study, authors addressed the temporal and spatial variation of heat content in surface air and moist enthalpy in the US High Plains regions by using hourly observation networks from 1985 to current, in which the hourly data sets are homogenous and quality data. We examined the temporal and spatial variations of surface temperature and heat content of surface temperature, as well as the variation of dry line between spring and summer seasons in the High Plains Region. We also compared our results with climate changes derived from daily data sets from the US Historical Climate Networks. Our assessments on the trend and variation of surface moist enthalpy provided a different view of climate change in the US High Plains Region.
