A new physical mechanism is proposed, liquid-in-solid convection, whereby heat is transported upward in molten blobs of magma, which rise through the solid Mantle as solid melts above and congeals below them due to convection within the blob. The blobs are initiated by Rayleigh-Bernard convection within the molten core, a stochastic process. Sufficiently large blobs carry their own magnetic field due to a magneto-hydrodynamic dynamo effect. Rising MHD dynamos account for rapid changes in the surface geomagnetic field such as the South Atlantic Anomaly. In reality blobs are greatly elongated vertically and are manifested as “plumes”, “diapers” and “LVZs”.

Carbon dioxide may be only one factor in climate change. Try the scenario I have discovered.

In reply to Harry W. Todd. Thank you for your consideration. My scientific effort is genuine. I think that the logic and evidence hang together well enough to warrant your expenditure of time and effort. We might discover a whole new way of looking at atmospheric science.

Have any of y’all ever considered the effect of paramagnetic oxygen in the atmosphere? I recently published a WordPress paper linking the wandering magnetic poles to the recent extreme weather and to the 1983 advent of the Ozone Hole. Read and study at https://www.harrytodd.org then give me your opinions. Thanks!

Unfortunately that image is static, i.e. August 3rd – 12th, 2011, as are all of the animations from NASA’s iNTEGRATED SPACE WEATHER ANALYSIS SYSTEM (iSWA):

Here is the comparable image as of today,
http://iswa.ccmc.gsfc.nasa.gov/IswaSystemWebApp/StreamByDataIdServlet?allDataId=892082357
but unless someone is willing to update the link every day there is no way to post the animation in our reference pages without it constantly being out of date.

In reply to Paul. Yes, NOAA's "Space Weather Prediction Center recently revamped its entire website" and broke all of their links. I have cleaned up most of them, if you find anything that still doesn't work please post them in comments. Thank you!

After having read a local story about a runway at Merrill Field changing its runway designation, I became curious again about magnetic north.It led me to find that there is striking similarities between the 10th and 11th generation of the IGRF. What I didn’t expect was that the last 7 years of calculations from each are identical in overall length and between years. Only that the 11th generation is 80km farther along the drift line than the 10th generation.

Anyone notice the increase in >5 mag earthquakes now that the CME has arrived

Some of these data-sets have KML plugins for Google Earth and allow for overlay of mag fields, aural data, earthquake and other references.
If they are available, with regular data-set updates, that might help.
Good stuff above…keep it coming!

Anthony,
Excellent addition to your set of reference pages. But scanning the list I don’t see the magnetometer chains. These are groups of magnetometer sensors, spread out over the globe, that report back their readings to their governing agency (usually at the national government level).
These groups provide the raw data for computing the various indices, such as Ap and Kp. But it’s interesting to watch them during a magnetic storm to get an idea of the strength and locality. (Not all geomagmetic disturbances come from the Sun).
Here’s a bunch that I use for reference:
U.S. Ge0logical service: http://geomag.usgs.gov/realtime/ (These are arranged so that the northern-most (“arctic”) sensors are at the top, but cover a lot of the Northern Hemisphere, from Guam to Alaska to Puerto Rico)
Canadian: http://geomag.nrcan.gc.ca/common_apps/auto_generated_products/stackplot_e.png (My favorite because it’s layed out correponding to the location of the sensor in Canada. You can observe a lot by watching these!)
Japanese: http://kogma.nict.go.jp/cgi-bin/geomag-interface (A little harder to use because you have to select the sensor from a list and look at them one at a time. But this came in handy during the X2.2 flare, which hit on the Asian side. You could clearly see the effect of the flare on magnetic readings)
HAARP: http://www.haarp.alaska.edu/haarp/data.html (HAARP has its own chain of magnetometers, including a very sensitive inductive magnetometer which can pick up ULF pulsations. [Be sure to wear a tin-foil hat when you visit this site, they can read your minds you know!])

The above Bz map is for crustal field, and should not be confused with the Earth’s field (100-200 stronger) as here:
