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...
متن کاملUPPER DEVONIAN ACRITARCHS AND MIOSPORES FROM THE GEIRUD FORMATION IN CENTRAL ALBORZ RANGE, NORTHERN IRAN

متن کاملDivision Rhyniophyta - Upper Silurian to Middle Devonian
Among the oldest convincing fossils of early vascular land plants are those of the Division Rhyniophyta. The members of this division consist of: (1) simple axes with cuticle, stomates, epidermis, cortex and a terete (circular) centrarch xylem (xylem development occurs from the center of the stem to the periphery), without well-developed appendages or roots; (2) simple, isotomous branching syst...
