Research findings from Goddard Space Flight Center update understanding of hydrometeorology
September 26th, 2008
"Anomalous atmospheric conditions can lead to surface temperature anomalies, which in turn can lead to temperature anomalies in the subsurface soil. The subsurface soil temperature (and the associated ground heat content) has significant memory-the dissipation of a temperature anomaly may take weeks to months-and thus subsurface soil temperature may contribute to the low-frequency variability of energy and water variables elsewhere in the system," scientists in the United States report.
"The memory may even provide some skill to subseasonal and seasonal forecasts. This study uses three long-term AGCM experiments to isolate the contribution of subsurface soil temperature...
