Evidence linking rapid Arctic warming to mid-latitude weather patterns
The effects of rapid Arctic warming and ice loss on weather patterns in the Northern Hemisphere is a topic of active research, lively scientific debate and high societal impact. The emergence of Arctic amplification--the enhanced sensitivity of high-latitude temperature to global warming--in only the last 10-20 years presents a challenge to identifying statistically robust atmospheric responses...
متن کاملEvidence linking Arctic amplification to extreme weather in mid-latitudes
[1] Arctic amplification (AA) – the observed enhanced warming in high northern latitudes relative to the northern hemisphere – is evident in lower-tropospheric temperatures and in 1000-to-500 hPa thicknesses. Daily fields of 500 hPa heights from the National Centers for Environmental Prediction Reanalysis are analyzed over N. America and the N. Atlantic to assess changes in north-south (Rossby)...
متن کاملEstimating the Response of Extreme Precipitation over Mid-latitude
Global warming induced changes in extreme orographic precipitation are investigated using a hierarchy of models: a global climate model, a limitedarea weather forecast model, and a linear mountain-wave model. We consider precipitation changes over an idealized north-south mid-latitude mountain barrier at the western margin of an otherwise flat continent. The intensities of the extreme events on...
متن کاملThe role of ionospheric clutter in mid-latitude and arctic regions for assessment of HFSWR surveillance
The ionosphere is the region of the earth’s atmosphere in which gases are ionized by radiation such as ultraviolet light from the sun and cosmic rays from outer space. The unwanted radar echoes from the ionosphere are collectively called ionospheric clutter. This paper studies the arctic and mid-latitude ionospheric environment using ionosonde data and assesses High-Frequency Surface-Wave Radar...
متن کاملEstimating the Response of Mid - latitude Orographic 1 Precipitation to Global Warming
5 The sensitivity of stratiform mid-latitude orographic precipitation to global mean temper6 ature is investigated through numerical simulations with a general circulation model. The 7 individual terrain elements are idealizations of the Earth’s major north-south mountain 8 chains and occupy four islands equally spaced around the northern hemisphere of a planet 9 otherwise covered by ocean. Pre...
