Abstract
The growth of forest is critically vulnerable to the change in rainfall and radiation than in air temperature. The amount of rainfall and cloudiness in the northeast region of the United States is assumed to be strongly affected by the Atlantic sea surface temperature (SST). The observational investigation of the relation between the greenness of three undisturbed forested areas in the Atlantic region and Atlantic SST is fundamental to understand the response of terrestrial ecosystems to climate change. Such teleconnection signals may also entail the change of natural variability associated with several hydrological parameters such as rainfall and runoff. We conducted short-term environmental change quantification using MODIS satellite imageries supplemented by NEXRAD data. Wavelet analysis was employed to derive climate signals and embedded patterns over the timescale to illuminate the propagation effects of climate teleconnection.
