• The Climatology of Blocking Anticyclones for the Northern and Southern Hemispheres: Block Intensity as a Diagnostic 

    Lupo, Anthony R., 1966-; Tikhonova, Elena A.; Mokhov, Igor I.; Wiedenmann, Jason M. (American Meteorological Society, 2002-12)
    A 30-yr climatology of blocking events was compiled by stratifying the data into seasonal and three regional categories for both the Northern and Southern Hemispheres using the NCEP-NCAR reanalyses. Several characteristics ...
  • A Climatology of Northern Hemisphere Blocking 

    Garcia-Herrera, Ricardo; Hernandez, Emiliano; Lupo, Anthony R., 1966-; Barriopedro, David (American Meteorological Society, 2006-03)
    In this paper a 55-yr (1948-2002) Northern Hemisphere blocking climatology is presented. Traditional blocking indices and methodologies are revised and a new blocking detection method is designed. This algorithm detects ...
  • The Wintertime Southern Hemisphere Split Jet: Structure, Variability, and Evolution 

    Lupo, Anthony R., 1966-; Atallah, Eyad H.; Cempa, Michael J.; Wasula, Thomas A.; Bosart, Lance F.; Bals-Elsholz, Teresa M. (American Meteorological Society, 2001-11)
    A persistent feature of the Southern Hemisphere upper-level time-mean flow is the presence of a split jet across the South Pacific east of Australia during the austral winter. The split jet is composed of the subtropical ...
