A climatology of stratospheric polar vortices and anticyclones
[1] United Kingdom Meteorological Office global analyses from 1991 to 2001 are used to create a global climatology of stratospheric polar vortices and anticyclones. New methodologies are developed that identify vortices in terms of evolving three-dimensional (3-D) air masses. A case study illustrates the performance of the identification schemes during February and March of 1999 when a merger o...
متن کاملStratospheric impact of the Chisholm pyrocumulonimbus eruption: 1. Earth-viewing satellite perspective
[1] The pyrocumulonimbus storm near Chisholm, Alberta, on 28 May 2001 has been studied in depth. However, the impact of this eruption on the lower stratosphere has not been characterized. Here and in a companion paper we explore this topic. This paper focuses on the ‘‘young’’ Chisholm smoke plume, from the age of 3 h to 1 week, as observed by Earth-viewing satellite instruments. (The companion ...
متن کاملSmall-scale mixing processes enhancing troposphere-to-stratosphere transport by pyro-cumulonimbus storms
Deep convection induced by large forest fires is an efficient mechanism for transport of aerosol particles and trace gases into the upper troposphere and lower stratosphere (UT/LS). For many pyro-cumulonimbus clouds (pyroCbs) as well as other cases of severe convection without fire forcing, radiometric observations of cloud tops in the thermal infrared (IR) reveal characteristic structures, fea...
متن کاملStratospheric ozone in boreal fire plumes – the 2013 smoke season over central Europe
In July 2013 very strong boreal fire plumes were observed at the northern rim of the Alps by lidar and ceilometer measurements of aerosol, ozone and water vapour for about 3 weeks. In addition, some of the lower-tropospheric components of these layers were analysed at the Global Atmosphere Watch laboratory at the Schneefernerhaus highaltitude research station (2650 m a.s.l., located a few hundr...
متن کاملClimatology of Cyclones, Anticyclones and Storm Tracks: Revision of Concepts
This paper has the finality of describe climatology of extratropical cyclones, anticyclones and storm tracks for the NH and SH. There is a long history of studies on the characteristics of synoptic systems, beginning with classical work on mid-latitude cyclones. For the SH, analyses of pressure data provide extensive statistics of the climatology of synoptic systems. Interestingly, the anticycl...
