RISAn Update of the Observed Quasi-Biennial Oscillation of the Stratospheric Winds over the Tropics
Publisher: American Meteorological Society
Abstract: A survey of the zonal wind in the stratosphere near the equator is made for the 32-year period 1953?84. The monthly mean zonal wind components have been calculated from daily observations at Canton Island, Gan, and Singapore ...
Evidence against an Antarctic Stratospheric Vortex Split during the Periods of Pre-IGY Temperature Measurements
Publisher: American Meteorological Society
Abstract: Historic upper-air observations from Antarctica are inspected to investigate the uniqueness of the vortex split in the Antarctic spring of 2002. No comprehensive meteorological observations are available prior to the ...
The Unusual Midwinter Warming in the Southern Hemisphere Stratosphere 2002: A Comparison to Northern Hemisphere Phenomena
Publisher: American Meteorological Society
Abstract: A strong midwinter warming occurred in the Southern Hemisphere (SH) stratosphere in September 2002. Based on experiences from the Northern Hemisphere (NH), this event can be defined as a major warming with a breakdown of ...
Diagnostic Comparison of Meteorological Analyses during the 2002 Antarctic Winter
Publisher: American Meteorological Society
Abstract: Several meteorological datasets, including U.K. Met Office (MetO), European Centre for Medium-Range Weather Forecasts (ECMWF), National Centers for Environmental Prediction (NCEP), and NASA?s Goddard Earth Observation ...
Simulations of Dynamics and Transport during the September 2002 Antarctic Major Warming
Publisher: American Meteorological Society
Abstract: A mechanistic model simulation initialized on 14 September 2002, forced by 100-hPa geopotential heights from Met Office analyses, reproduced the dynamical features of the 2002 Antarctic major warming. The vortex split on ...
