On Atmospheric-Oceanic-Land Temperature Variability and Trends

Oceanic-atmospheric variability and western U.S. snowfall

[1] A study of the influences of interdecadal and interannual oceanic-atmospheric influences on April 1 Snow-Water Equivalent (SWE) in the western U.S. is presented. SWE data was identified at 323 Natural Resources Conservation Service (NRCS) SNOTEL (SNOwpack TELemetrysites) stations for the period of 1961 to 2004 and for 121 SNOTEL stations for the period 1941 to 2004. The phases (cold/negativ...

Coupled Oceanic-Atmospheric Variability and U.S. Streamflow

The Oceanic Variability Spectrum and Transport Trends

Oceanic meridional transports evaluated over the width of the Pacific Ocean from altimetric observations become incoherent surprisingly rapidly with meridional separation. Even with 15 years of data, surface slopes show no significant coherence beyond 5° of latitude separation at any frequency. An analysis of the frequency/zonal-wavenumber spectral density shows a broad continuum of motions at ...

Volatility in atmospheric temperature variability

Using detrended fluctuation analysis (DFA), we study the scaling properties of the volatility time series Vi = |Ti+1 − Ti| of daily temperatures Ti for ten chosen sites around the globe. We find that the volatility is long range power-law correlated with an exponent γ close to 0.8 for all sites considered here. We use this result to test the scaling performance of several state-of-the art globa...

Climate Variability Impacts on Land Use and Livelihoods in Drylands

This edited volume is devoted to the examination of the implications of the inevitable changes wrought by global change on the welfare and livelihoods of tens of millions of people who live in dryland regions. Global change is more than just climate change and the ramifications of changing trade patterns (geopolitical and economic aspects), the shift to the market economy, demographic factors (...
