On the spatial, temporal, and seasonal variations of climatological variables, and the impact of stratospheric volcanic aerosols on climate in the southeastern US
- North Carolina State Univ., Raleigh, NC (United States)
The first objective of this study is to analyze climate data (including the duration of growing season, mean maximum, minimum, and daily temperatures and precipitation) in the southeastern US during the period of 1949 to 1994 by a statistical analysis system regression model. The following topics are addressed: (1) identification of any changes in the duration of the growing season since 1949, (2) identification of any differences in temperatures (minimum, maximum, daily) and in the temperature range since 1949, and (3) identification of any changes in the precipitation pattern since 1949. The second objective of this study is to identify the volcanic signal in the surface temperature in the southeastern US due to the eruption of Mt. Pinatubo. Results of the first part of the study indicated a longer growing season, a decrease in mean daily temperature, an increase in precipitation, and a decrease in annual, winter, and summer mean maximum temperature. Aerosol radiative forcing is identified as one of the reasons leading to the widespread decrease in the diurnal temperature range in the southeastern US. 13 refs., 4 figs., 3 tabs.
