Abstract: Changes in the intra-annual cycle of atmospheric CO2 at Mauna Loa, Hawaii, are investigated by comparing monthly observations to the mean value of each year?s waxing and waning phase of the cycle. Results identify a ...

Abstract: An energy balance climate model with latitudinal, surface?air, and land?sea resolution is coupled to a two-dimensional (latitude?depth) ocean model and used to simulate changes in surface and surface air temperature since ...

Abstract: Many climate studies need to generate estimates of a climate variable at a given location based on values from other locations. In this research, a new method for the spatial interpolation of daily maximum surface air ...

Abstract: Feedbacks of vegetation on summertime climate variability over the North American Grasslands are analyzed using the statistical technique of Granger causality. Results indicate that normalized difference vegetation index ...

Abstract: The authors use the notion of Granger causality to investigate the relationship between the North Atlantic Oscillation (NAO) index and the sea surface temperatures (SSTs) over the Northern Hemisphere. The Granger causality ...

Abstract: The authors establish the effect of urbanization on precipitation in the Pearl River Delta of China with data from an annual land use map (1988?96) derived from Landsat images and monthly climate data from 16 local ...

Abstract: This paper uses statistical and analytical techniques to investigate intraseasonal interactions between temperature and vegetation [surrogated by the normalized difference vegetation index (NDVI)] over the boreal forests. ...

Abstract: A coupled linear model is derived to describe interactions between anomalous precipitation and vegetation over the North American Grasslands. The model is based on biohydrological characteristics in the semiarid environment ...
