Development of the Pan-Arctic Snowfall Reconstruction: New Land-Based Solid Precipitation Estimates for 1940–99
A new product, the Pan-Arctic Snowfall Reconstruction (PASR), is developed to address the problem of cold season precipitation gauge biases for the 1940–99 period. The method used to create the PASR is different from methods used in other large-scale precipitation data products and has not previously been employed for estimating pan-arctic snowfall. The NASA Interannual-to-Seasonal Prediction P...
متن کاملImportance of autumn Arctic sea ice to northern winter snowfall.
In their contribution to PNAS, Liu et al. (1) suggested that the recent decline of Arctic sea ice has played a critical role in recent cold and snowy winters in the Northern Hemisphere (NH). This study is very interesting, but we believe it deserves several clarifications. First, in 2010, Wu et al. (2) discovered the importance of autumn Arctic sea ice in triggering regional cold extremes; for ...
متن کاملTemperature and precipitation history of the Arctic
As the planet cooled from peak warmth in the early Cenozoic, extensive Northern Hemisphere ice sheets developed by 2.6 Ma ago, leading to changes in the circulation of both the atmosphere and oceans. From w2.6 to w1.0 Ma ago, ice sheets came and went about every 41 ka, in pace with cycles in the tilt of Earth’s axis, but for the past 700 ka, glacial cycles have been longer, lasting w100 ka, sep...
متن کاملpatterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
