Long Term Movement of the North Magnetic Pole Introduction


01.gif
2011-1-7 00:57




The accompanying figure shows the path of the North Magnetic Pole since its discovery in 1831 to the last observed position in 2001. During the last century the Pole has moved a remarkable 1100 km. What is more, since about 1970 the NMP has accelerated and is now moving at more than 40 km per year. If the NMP maintains its present speed and direction it will reach Siberia in about 50 years. Such an extrapolation is, however, tenuous. It is quite possible that the Pole will veer from its present course, and it is also possible that the pole will slow down sometime in the next half century.

The strength and direction of the Earth's magnetic field slowly change with time ¡V a phenomenon referred to as secular change or secular variation. The cause of secular variation is related to the process by which the magnetic field is generated. Secular change occurs everywhere on Earth, but the magnitude of the change varies from place to place and also with time.

03.gif
2011-1-7 00:58



The magnetic field in the region of North Magnetic Pole experiences secular variation just like the magnetic field at any other location on the Earth's surface. To illustrate how this leads to the movement of the Magnetic Pole, consider Observer A , standing at the North Magnetic Pole on January 1. On that day he observes that the inclination is exactly 90¢X, as expected. Repeat observations made at exactly the same spot during the year show that the inclination is slowly decreasing. On January 1 of the following year he observes an inclination of 89¢X 57'. During the same time interval, Observer B, who is standing 40 km northwest of Observer A notices that the inclination has increased to 90¢X. He is now at the North Magnetic Pole. So the slow motion of the Magnetic Pole across the Arctic is due to the secular variation of the magnetic field, a process that originates in the outer core of the Earth, approximately 3000 km below the surface.

    Earth's magnetic south pole is where the magnetic field lines are oriented vertically and come out of the surface of the Earth. The magnetic inclination is thus defined as -90 degrees. The magnetic pole varies in position on a yearly basis due to secular variation (drift in Earth's magnetic field). Australian explorers T.W. Edgeworth David and D. Mawson were the first to claim to have located the magnetic south pole in 1909 as part of the Shackleton expedition of 1907-1909. However, their location was subsequently found to be incorrect and the most likely location of the pole in 1909 is 71¢X36'S 152¢X0'E.


    Below is a map showing the measured location of the magnetic south pole (also known as the dip pole) over the past few years [Merrill, McElhinny and McFadden, 1998].

      The definition of Earth's magnetic poles depends on what is being defined. The "magnetic north/south dip pole" is the measured location of the vertical field lines. This is different from the "Geomagnetic north/south pole", which is the location where the best fitting dipole model pierces the surface of the Earth. While magnetic poles are not necessarily 180 degrees opposite from one another, Geomagnetic poles are exactly 180 degrees opposite from one anotherThe magnetic south dip pole in 1990 was at 64.9¢X S 138.9¢X EThe geomagnetic axial dipole south pole in 1990 was 79.2¢X S 180.9¢X EThe following table is a list of historical measured locations for the south dip pole. The last land based location for the magnetic south dip pole was in 1962. The magnetic south dip pole has now moved offshore.

TAMPA ¡V Scientists say the magnetic north pole is moving toward Russia and the fallout has reached ¡X of all places ¡X Tampa International Airport.
The airport has closed its primary runway until Jan. 13 to repaint the numeric designators at each end and change taxiway signage to account for the shift in location of the Earth's magnetic north pole.
The closure of the west parallel runway will result in more activity on the east parallel runway and more noise for residential areas of South Tampa.

The busiest runway will be re-designated 19R/1L on aviation charts.
It's been 18R/36L, indicating its alignment along the 180-degree approach from the north and the 360-degree approach from the south.


Later this month, the airport's east parallel runway and the seldom used east-west runway will be closed to change signage to their new designations.

The Federal Aviation Administration required the runway designation change to account for what a National Geographic News report described as a gradual shift of the Earth's magnetic pole at nearly 40 miles a year toward Russia because of magnetic changes in the core of the planet.

But, even w/oa polar shift, a solar CME large enough could bring particles down to the deck if earth is in the wrong place at the wrong time with our current magnetic field protection.

Eruptions from the Far-Side: New Global Views of the Sun

AGU 2010 Fall Meeting ¡V

New observations of the Sun indicate that the search for the factors that play a role in the initiation and evolution of eruptive and explosive events, sought after for improved space-weather forecasting, requires knowledge of much, if not all, of the solar surface field.

The combination of observations from two NASA missions, the Solar Dynamics Observatory (SDO) and the Solar TErrestrial RElations Observatory (STEREO) enable us to view much of the solar surface and atmosphere simultaneously and continuously for the first time.

These near-global observations often show long-distance interactions between magnetic areas that exhibit flares, eruptions, and frequent minor forms of activity.

These interactions were previously suspected, but have never been observed until now.

We analyzed a series of flares, filament eruptions, coronal mass ejections, and related events which occurred on 1¡V2 August 2010.

These events extended over a full hemisphere of the Sun, only two-thirds of which is visible from the Earth's perspective. Source: AGUvideos¨Ó·½¡G AGUvideos
