Anomalous Atmospheric Circulation Associated with the Extremely Persistent Dense Fog Events over Eastern China in the Late Autumn of 2018

چکیده
Under a declining trend of fog days in China, the duration events since 1990s reached significant peak late autumn 2018 over Eastern China. The average anomalous were 4.74 d November Jiangsu Province with 1.73 standard deviation departure from climatology. Those fogs can thus be identified as significantly abnormal climatic event long duration, strong intensity, and extensive coverage. Based on daily evolutions correlations atmospheric parameters, dense are revealed to well configured by favorable metrological conditions such weak dynamic progress, inversion lower troposphere saturated air near surface. If not disturbed, intensification or these will further promote maintain development fogs. background associated those meteorological is composing standardized anomalies circulation fields during days. Over areas, vortex activities cold invasion effectively hampered atmosphere inclines stable, due pattern composed broadened jet stream, weakened core undermined East Asian trough, declined winter monsoon, enhanced southerly flows that transport warm wet vapor supplement intensified both sustained northward wind at westward near-surface. Overall, numbers 1000–200-hPa height, temperature, wind, moisture all depart climatology for locale time season, demonstrating persistent China an unusual weather extreme synoptic-scale departures normal.
