Oceanic-atmospheric variability and western U.S. snowfall

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

Interannual variability in western US precipitation

Low-frequency (interannual or longer period) climatic variability is of interest, because of its significance for the understanding and prediction of protracted climatic anomalies. Since precipitation is one of the key variables driving various hydrologic processes, it is useful to examine precipitation records to better understand long-term climate dynamics. Here, we use the multi-taper method...

NOTES AND CORRESPONDENCE Tropical Atmospheric Variability Forced by Oceanic Internal Variability

Atmospheric general circulation model experiments are conducted to quantify the contribution of internal oceanic variability in the form of tropical instability waves (TIWs) to interannual wind and rainfall variability in the tropical Pacific. It is found that in the tropical Pacific, along the equator, and near 25°N and 25°S, TIWs force a significant increase in wind and rainfall variability f...

Time-Series Measurements of Atmospheric and Oceanic CO2 and O2 in the Western Gulf of Maine

A collaboration has been established between the University of New Hampshire’s (UNH) Joint Center for Ocean Observing Technology and NOAA’s Pacific Marine Environmental Laboratory (PMEL) to adapt and deploy an autonomous carbon dioxide measurement system on a moored platform in the coastal Western Gulf of Maine. This buoy provides high-resolution timeseries measurements of atmospheric and ocean...
