Northern Hemisphere Airstream Regions

摘要: Abstract Near-surface airstream source regions of the Northern Hemisphere have been identified using 16-year mean resultant winds from 3° latitude by longitude grids. Tracing airstreams back to their divergent centers reveals 19 different sources during various seasons year. Five these sources(air originating over North and South Pacific Atlantic Oceans air Turkey) are resident in 12 months Another three (central Asian, Arctic central East Asian air) exist for at least 11 per The remaining present 1–9 year area influence is much less than that 5 year-long sources. In mean, there several favored locations frontal zones, e.g., a north–south band Mexico (dividing air), northern America, two northeast–southwest trending bands cast coasts Asia representing lea...
