Abstract
- This paper diagnoses the temperature trends in maximum ( T<subscript>max</subscript>) and minimum temperatures ( T<subscript>min</subscript>) over a selection of 65 stations spread over the southeast United States (SEUS) from three observed datasets. They are the Cooperative Observer network program (COOP), the COOP data corrected for documented shifts in time of observation (COOP1), and the COOP data additionally corrected for documented changes in instrumentation (COOP2). These 65 stations have been isolated for having the three observed datasets for the same time period from 1948 to 2009. The authors' comparisons suggest that COOP2 displays stronger warming (cooling) trends in T<subscript>max</subscript> ( T<subscript>min</subscript>) compared with COOP1 in all four seasons. This is consistent with the expectation from the bias correction applied for the instrument change. In comparison, the differences between COOP and COOP2 are relatively larger. In the spring, summer, and fall seasons, the median T<subscript>max</subscript> trend is warming in COOP2 while it is cooling in COOP. In the winter season, the median trends of T<subscript>max</subscript> in the two datasets are positive, but their magnitudes are substantially different. Similarly, in the winter, summer, and fall seasons, the warming trend in T<subscript>min</subscript> in COOP is contrary to the cooling trend in COOP2. In the spring season, the median trend in T<subscript>min</subscript> is comparable between the two datasets. COOP2 shows the relationship of trends in T<subscript>min</subscript>, with the extent of urbanization in these 65 stations, to be statistically significant and to be consistent with expectations from theory in contrast to the COOP data.
