Solar and Heliospheric Forecasts
Entry ID: Solar-Helio_Weather_Model
[ Update this Record ]


Summary
Abstract: The forecast of solar and heliospheric information is based on assimilation (by
direct insertion) of SOHO/MDI observations or, if not available, NSO/KPVT
observations (weather permitting) within 52 degrees of disk center (outlined by
the grey oval; disk center is identified by a black-and-white square; NOAA
active region numbers are shown 5-10 degrees poleward of the regions; the
approximate edge of the disk - ignoring the solar tilt angle - is marked by
vertical lines). Outside the front-side assimilation area, the magnetic
concentrations are moved in simulated supergranular and meridional flows and
differential rotation, while maintaining the mixed-polarity network by the
injection of ephemeral regions (see descriptions in the literature).
Helioseismic data are used to introduce any large active regions that are
suggested by their acoustic signature on the far side of the solar sphere. The
most recent full-sphere field map based on observed magnetograph and
helioseismic data is shown to the left (and below in a larger format); the
corresponding farside acoustic information is shown below these maps for
comparison, using data from one day earlier. The 3-week forecast (accessible
through links to the left and above) is based on this map, subjecting the field
to random walk, collisional interactions, differential rotation, and meridional
flow.
