  <dc:description>&lt;p&gt;&lt;span&gt;Both the dipole and nondipole components of the&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;present&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;geomagnetic&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;field&lt;/span&gt;&lt;span&gt;&amp;nbsp;are analyzed by calculating the orientation of hypothetical geocentric dipoles which, if acting alone, would produce the&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;present&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;geomagnetic&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;field&lt;/span&gt;&lt;span&gt;&amp;nbsp;as observed at points on a grid covering the earth at 10° intervals. The dispersion in direction of these virtual&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;geomagnetic&lt;/span&gt;&lt;span&gt;&amp;nbsp;poles due to the nondipole component of thee&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;geomagnetic&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;field&lt;/span&gt;&lt;span&gt;&amp;nbsp;(1) is larger in the southern hemisphere than in the northern; (2) increases with increase in latitude; (3) at all latitudes is of the same order of magnitude as the dispersion due to a wobble of several tens of degrees of the main geocentric dipole; (4) is anomalously small over a region of continental dimensions in the central Pacific ocean. The parameters describing these variations of poles are transformed to parameters describing variations of the&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;geomagnetic&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;field&lt;/span&gt;&lt;span&gt;&amp;nbsp;for&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;comparison&lt;/span&gt;&lt;span&gt;&amp;nbsp;with&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;paleomagnetic&lt;/span&gt;&lt;span&gt;&amp;nbsp;data.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;</dc:description>
