Hello all,

I am pleased to tell you that we (the JUPOS team and I) have posted another major report on the long-term features of Jupiter, this one covering the high southern latitudes from 36 to 61 deg.S. It is in similar style to our report last year on the South Temperate domain. A brief summary is below, and an Extended Summary is attached. You can find the whole report, in several files including appendices and full-size figures, on the Reference Articles page of our web site, and directly at:

http://www.britastro.org/jupiter/sstemp2014.htm

Thanks and congratulations to all the observers over the past 14 years who have enabled these results to be obtained. And thanks to Damian Peach for posting the report.

We hope you enjoy looking at it!

John

Summary:

Here we present an overview of the three domains in high southern latitudes of Jupiter, from 36 to 61 deg.S. Domains are defined as latitude bands bounded by prograde jets, and we propose a simplified nomenclature for the high-latitude domains and jets. We survey the dynamical characteristics of the S2, S3, and S4 domains, and of the S2, S3, and S4 prograde jets on their north edges. We also summarise the long-term history of the major features, especially the long-lived anticyclonic ovals. This report covers the years 2001-2012, from the JUPOS database, with more limited summaries of some aspects back to 1986.....

サマリー：

ここでは、木星の南緯36度から61度までの南半球高緯度の３個の領域の概要を示す。領域は前進ジェット気流によって囲まれた緯度帯として定義され、高緯度領域とジェット気流について単純化された命名法を提案する。我々は、S2,S3,S4領域と、それらの北端のS2,S3,S4前進ジェット気流の動的性質を調査している。また、主要な模様、特に長寿命の高気圧性白斑の長期的な歴史をまとめる。このレポートはJUPOSデータベースからの2001-2012年をカバーしているが、さかのぼって1986年までのいくつかの外観を限定的にまとめている。
