“…The three‐dimensional HAFv2 kinematic model projects radial solar wind flow from inhomogeneous sources on a surface at 2.5 solar radii out into space while adjusting the flow for stream‐stream interactions as fast streams overtake slower ones. The stream‐stream interaction procedure is described in great detail by Olmstead and Akasofu [1985] and Fry and Akasofu [1987]. Stream‐stream interactions are handled in a manner that mimics the net result of the collisionless interactions of solar wind plasma and fields.…”

[1] We use the space weather validated 3-D HAFv2 model to help us study the interplanetary propagation of the October/November 2003 solar eruptions from the Sun to >90 AU and over a wide range of heliolongitudes and heliolatitudes. The HAFv2 model predictions at ACE (1 AU), Ulysses (5.23 AU), Cassini (8.67 AU), Voyager 2 (73 AU), and Voyager 1 (93 AU) are compared with available data. These comparisons indicate the importance of asymmetric interplanetary propagation both in heliolongitude and heliolatitude. We recommend that these effects explicitly be taken into account. The HAFv2 results appear to be useful for interpreting the Voyager 2 and Voyager 1 energetic particle data in the outer heliosphere. They are consistent with the effects of the Halloween solar events observed in the energetic particle data at both spacecraft. The HAFv2 results also may be helpful for predicting the plasma wave 2-3 kHz radio emission previously associated with large shocks and their interaction with the heliopause. Our study indicates that the Halloween events may give rise to 2-3 kHz radio emission in early 2005, assuming that the shocks which propagated beyond Voyager 1 will be strong enough.

“…Thus, by integrat ing the velocity as a function of time graphically, one can determine the distance traveled by individual particles. This method has been carefully calibrated on the basis of MHD solutions by Olmsted and Akasofu (1985), , and Olmsted and Akasofu (1986).…”

“…Although this method does not explicitly consider the simultaneous solution of the conservation equations, it can be calibrated (Olmsted and Akasofu, 1985) with the use of known l-1/2D MHD solutions (Dryer and Steinolfson, 1976;Smith et al, 1985) for the case of co-rotating streams.…”

An MHD 2-1/2D, time-dependent model is used, together with observations of six solar flares during 3-7 February 1986, to 'demonstrate global, large-scale, compound disturbances in the solar wind over a wide range of heliolongitudes. This scenario is one that is likely to occur many times during the cruise, possibly even encounter, phases of the Multi-Comet Mission. It is suggested that a model such as this one should be tested with multi-spacecraft data (such as the MCM and Earth-based probes) with several goals in view: (1) utility of the model for operational real-time forecasting of geomagnetic storms, and (2) scientific interpretation of certain forms of cometary activities and their possible association with solar-generated activity.
