“…more impervious surfaces) than climatological factors (Mao and Cherkauer, 2009). While the total annual precipitation increased, the number of dry periods also increased (Peterson and Baringer, 2009). In Canada, more areas were affected by extreme dry or wet conditions from the 1950-1998 period as compared to the 1900-1949 period (Zhang et al, 2000).…”

“…0.5 C per decade) observed since the early 1980s at Coweeta is consistent with other global and regional observations. In the observed climate records, globally, the 20 warmest years have all occurred since 1981 (Peterson & Baringer 2009). Across the USA, a significant warming trend in air temperature also began in the late 1970s to early 1980s (Groisman et al 2004;Peterson & Baringer 2009).…”

Coweeta Hydrologie Laboratory, located in western North Carolina, USA, is a 2,185 ha basin wherein forest ciimate monitoring and watershed experimentation began in the early 1930s. An extensive ciimate and hydrologie network has facilitated research for over 75 years. Our objectives in this paper were to describe the monitoring network, present long-term air temperature and precipitation data, and analyze the temporal variation in the long-term temperature and precipitation record. We found that over the period of record: (1) air temperatures have been increasing significantly since the late 1970s, (2) drought severity and frequency have increased with time, and (3) the precipitation distribution has become more extreme over time, we discuss the implications of these trends within the context of regional and global climate change and forest health.

“…The SST plays a role in TC genesis (Peterson and Baringer 2009) and many studies (e.g., Bengtsson et al 1996;Royer et al 1998;Sugi et al 2002;McDonald et al 2005;Yoshimura et al 2006;Landsea 2007;Knutson et al 2008Knutson et al , 2010a suggest that in a warmer climate, there might be changes in TC frequency, and the vast majority of climate models suggest decreases in global tropical cyclone numbers (Knutson et al 2010a).…”

Effects of Tropical Cyclones on Ocean Heat Transport in a High-Resolution Coupled General Circulation Model

In this paper the interplay between tropical cyclones (TCs) and the Northern Hemispheric ocean heat transport (OHT) is investigated. In particular, results from a numerical simulation of the twentieth-century and twenty-first-century climates, following the Intergovernmental Panel on Climate Change (IPCC) twentiethcentury run (20C3M) and A1B scenario protocols, respectively, have been analyzed. The numerical simulations have been performed using a state-of-the-art global atmosphere-ocean-sea ice coupled general circulation model (CGCM) with relatively high-resolution (T159) in the atmosphere. The CGCM skill in reproducing a realistic TC climatology has been assessed by comparing the model results from the simulation of the twentieth century with available observations. The model simulates tropical cyclone-like vortices with many features similar to the observed TCs. Specifically, the simulated TCs exhibit realistic structure, geographical distribution, and interannual variability, indicating that the model is able to capture the basic mechanisms linking the TC activity with the large-scale circulation. The cooling of the surface ocean observed in correspondence of the TCs is well simulated by the model. TC activity is shown to significantly increase the poleward OHT out of the tropics and decrease the poleward OHT from the deep tropics on short time scales. This effect, investigated by looking at the 100 most intense Northern Hemisphere TCs, is strongly correlated with the TC-induced momentum flux at the ocean surface, where the winds associated with the TCs significantly weaken (strengthen) the trade winds in the 58-188N (188-308N) latitude belt. However, the induced perturbation does not impact the yearly averaged OHT. The frequency and intensity of the TCs appear to be substantially stationary through the entire 1950-2069 simulated period, as does the effect of the TCs on the OHT.
