RELATION BETWEEN GEOMAGNETIC ACTIVITY AND PRESSURE VARIATIONS ALOFT

Abstract

The superposed-epoch method is used to try to find a relationship between pressure aloft and geomagnetically quiet and geomagnetically disturbed days. No relation is observed between geomagnetically disturbed days and pressure aloft. A relationship seems to exist between geomagnetically quiet days and pressure aloft and is best observed at and north of 60°N. The greatest number of statistically significant pressure variations occur on the third through the sixth days following the geomagnetically quiet days.
