      This relationship can be defined in terms of ENSO
      where flaring with the El Nino actually causes that
      third van Allen belt. Of course, ocean conductivity
      relative to temperature and salinity will come to play . .
      . so perhaps this won't tell us something that can
      be mathematically modeled, but it does offer some
      good observational pictures about what is going on
      with cirrus clouds.<br><br>With ENSO, by definition,
      El Nino is a reverse of winds. This is really
      significant, because that means that the third van Allen belt
      at some<br>point isn't about the difference between
      the ocean current and the flaring, but the SUM of
      them! This also may be something that a mathematical
      relationship can be framed with. It may be a function of SST
      anomaly area. There is a point that the movement in the
      ionosphere<br>causes WARMING on the surface were the anomaly warm SSTs
      form near Peru, which in turn causes a wind
      reversal--to me this is a very interesting<br>point. Further,
      there is a the extreme of the La Nina where the ocean
      negitive induction dominates and prevents any cirrus
      activity.<br><br>Finally, flaring and moving ions in the ionosphere,
      expanding and contracting with the day may be easier to
      calculate in terms of<br>setting up a relationship to
      figure what exactly the field forces from the fields
      created in the oceans are. This is very difficult to put
      into<br>words, so if this is confusing, I will state it another
      way.

        On Feb 28th, the Interplanetary Magnetic Field
        swung to a strong south-pointing orientation. That,
        coupled with an elevated solar wind speed and density,
        triggered a G-1 class geomagnetic storm. The result was
        some high latitude aurora. See this link for a
        photgraph of aurora observed over Quebec :
        <a href=http://www.spaceweather.com/aurora/images/01mar02/Moussette2.jpg target=new>http://www.spaceweather.com/aurora/images/01mar02/Moussette2.jpg</a> . As of right now, there are 3 sunspot regions,
        namely 9839, 9842, and 9845, that appear to be capable
        of producing M-class flares. Regions 9839 and 9842
        are close to rotating out of view over the western
        limb of the solar disk. Sunspot region 9845, however,
        is close to the sun's central meridian. A rather
        large coronal hole is also approaching the sun's
        central meridian, and coming into an Earth-pointing
        position. High speed colar wind gusts are likely around the
        first of next week.<br><br>The current solar and
