Atmospheric circulation around the Greenland Crest

Will Greenland melting halt the thermohaline circulation?

[1] Climate projections for the 21st century indicate a gradual decrease of the Atlantic Meridional Overturning Circulation (AMOC). The weakening could be accelerated substantially by meltwater input from the Greenland Ice Sheet (GIS). Here we repeat recent experiments conducted for the Intergovernmental Panel of Climate Change, providing an idealized additional source of freshwater along Green...

Investigation of the atmospheric circulation anomalies associated with extreme rainfall events over the Coastal West Africa

This study investigates the atmospheric circulation associated with extreme rainfall events over the coastal West Africa. The rainfall data of this study were obtained from the Global Precipitation Climatology Centre (GPCC), spanning from 1981 to 2010. The atmospheric datasets were also obtained from the ERA-Interim reanalysis. The study employed the Z-Index to categorize dry and wet years into...

Upper-air temperatures around Greenland: 1964–2005

[1] A 42-year collection of 12h balloon soundings from six sites surrounding Greenland reveal distinct patterns of tropospheric and stratospheric temperature variability. Seasonal mean upper-air temperatures exhibit statistically significant correlations with surface air temperature records. Over the full 1964–2005 record, patterns of statistically significant tropospheric warming and stratosph...

active facilitation. It might also be argued that the drug was operating on consolidation processes. Since it is generally assumed that consolidation is a progressive stabilization of a memory trace over time, our data suggest that this labile phase of memory lasts for at least 5 days. That there was a trend toward facilitation in the LD(l) group supports this contention. The same trend, howeve...
