Variation of temperature in the troposphere and lower stratosphere

Abstract Correlation coefficients are evaluated between temperatures at 500 mb and at three levels in the lower stratosphere (highest 60 mb) and, respectively, the pressure at the tropopause and the height of the 300‐mb level for Larkhill and Lerwick for each month of the year. Similar coefficients...

Description
Summary:Abstract Correlation coefficients are evaluated between temperatures at 500 mb and at three levels in the lower stratosphere (highest 60 mb) and, respectively, the pressure at the tropopause and the height of the 300‐mb level for Larkhill and Lerwick for each month of the year. Similar coefficients are also given for Malta and (for different levels) for Arctic Bay for January, April, July and October. The Dines type of relationship is confirmed for those regions and seasons affected by travelling depressions and anticyclones. There is no significant correlation between similar parameters for Aden and tropical islands in the Pacific. The relation between temperature in the lower stratosphere and, respectively, the level of the tropopause and the height of the 300‐mb level decreases by a factor of 2 or more between the levels of 150 mb and 60 mb at Larkhill, Lerwick and Malta, indicating a marked decrease with height in the effect of tropospheric disturbances on stratospheric temperatures. The stratospheric correlation coefficients for Larkhill and Lerwick have a significant minimum in the winter.
