5Wind and Temperature Observations NWS and SRNL data show the mean annual daytime and nighttime temperatures are increasing ~0.04 and ~0.05 ºC respectively, per year.The wind speed is decreasing for this area of the Southeast.
14E and A for Daytime and Nighttime E for daytime and nighttime from SRNL Area Towers is increasing at a rate of ~0.03 and ~0.01 degrees per year, respectively.A for daytime from the SRNL Area Towers is increasing at a rate of ~0.03 degrees per year. Nighttime values are decreasing by ~0.10 degrees per year.
15ConclusionsDaytime and nighttime temperatures are increasing ~4 and ~5 ºC respectively, per century.Daytime and nighttime speeds are decreasing ~0.9 and ~1.4 m/s respectively, per centuryIncreases in E for daytime and nighttime suggest that convective turbulence is increasing. This is probably due to a decrease in the thermal stability between the surface and the 60-m level.The daytime rate for E is increasing more rapidly than the nighttime rate.
