Abstract: In the tropics of the Southern Hemisphere the zonal wind in the troposphere above the 500-mb level has a well defined half-yearly oscillation with westerly maxima (easterly minima) in May and November. It is demonstrated ...

Abstract: We have tested three methods of estimating the level of a coming season's mean temperature at a station where the statistical association between two selected seasons is as high as one can expect in extratropical regions. ...

Abstract: This note deals with the standard deviations of 24-hr changes in 10-mb temperatures and heights. The standard deviations are differently distributed in disturbed and in quiet winter months. In the disturbed months their ...

Abstract: Two patterns dominate changes of monthly mean temperature and pressure-height in the stratosphere. In the one, the middle latitudes vary oppositely to low and high latitudes, and in the other the changes at higher latitudes ...

Abstract: Development is described of a Comprehensive Ocean-Atmosphere Data Set (COADS)?the result of a cooperative project to collect global weather observations taken near the ocean's surface since 1854, primarily from merchant ...

Abstract: The NCEP and NCAR are cooperating in a project (denoted ?reanalysis?) to produce a 40-year record of global analyses of atmospheric fields in support of the needs of the research and climate monitoring communities. This ...
