The zonal asymmetry in the Antarctic total ozone column (TOC) has been widely studied in … recent decades. However, little is known about how spatially dependent the TOC response is to sudden … stratospheric warmings (SSWs).
The parameterization of gravity waves in the NCAR Whole Atmosphere Community Climate Model (WACCM) includes orographic, convective, and frontal sources. Even with these, the model simulates temperatures in the Antarctic lower stratosphere during winter and spring that are much lower than observed.
The composition of the stratosphere is driven by transport, temperatures and processes in the tropical tropopause layer – this has implications for ozone, radiation, and surface climate. The properties of the tropical tropopause layer have changed in recent decades, e.g.
Ozone climatologies are presented for a number of locations in the Australian region, making use of … both total ozone and ozone profile data, as measured by the Bureau of Meteorology’s Dobson and … ozonesonde networks. For mid-latitude sites (Melbourne and Macquarie Island)…
