Changing Northern Hemisphere Snow Seasons
Spatial and temporal patterns in the onset, offset, and length of the snow season across Northern Hemisphere continents are examined for the period from 1967 to 2008. Full snow seasons (FSS) and core snow seasons (CSS) are defined based on the consistency of snow cover within a location over the course of the cold season. Climatologically, the seasonal onsets of FSS and CSS progress more rapidl...
متن کاملNorthern hemisphere winter storm tracks of the Eemian interglacial and the last glacial inception
Climate simulations of the Eemian interglacial and the last glacial inception have been performed by forcing a coupled ocean-atmosphere general circulation model with insolation patterns of these periods. The parameters of the Earth’s orbit have been set to conditions of 125 000 and 115 000 years before present (yr BP). Compared to today, these dates represent periods with enhanced and weakened...
متن کاملDeconstructing the climate change response of the Northern 1 Hemisphere wintertime storm tracks
There are large uncertainties in the circulation response of the atmosphere to climate change. 6 One manifestation of this is the substantial spread in projections for the extratropical storm tracks made 7 by different state-of-the-art climate models. In this study we perform a series of sensitivity experiments, 8 with the atmosphere component of a single climate model, in order to identify the...
متن کاملChanging Northern Hemisphere Storm Tracks in an Ensemble of IPCC Climate Change Simulations
Winter storm-track activity over the Northern Hemisphere and its changes in a greenhouse gas scenario (the Special Report on Emission Scenarios A1B forcing) are computed from an ensemble of 23 single runs from 16 coupled global climate models (CGCMs). All models reproduce the general structures of the observed climatological storm-track pattern under present-day forcing conditions. Ensemble mea...
متن کاملThe Life Cycle of the Northern Hemisphere Sudden Stratospheric Warmings
Motivated by recent evidence of strong stratospheric–tropospheric coupling during the Northern Hemisphere winter, this study examines the evolution of the atmospheric flow and wave fluxes at levels throughout the stratosphere and troposphere during the composite life cycle of a sudden stratospheric warming. The composite comprises 39 major and minor warming events using 44 years of NCEP–NCAR re...
