![]() ![]() The blue arrows are outward directed flux and the red, inward flux. Each "arrow" represents a "unit" of photospheric magnetic flux, 10 23 Mx per blue or red arrow, and is pointed in the direction the flux is moving, relative to the fluid. The display uses a Mercator projection, rather than the more common, solar equal area projection consequently we have foreshortened the arrow sizes with latitude, to help illustrate this. The Display in the top middle is this model’s synoptic map of the photosphere, with the field entities shown. Netlogo Interface for nominal “Solar Field Mapping 1.07” model at 161 ticks time, with random seed 314159. Heliosphere Magnetic fields Solar activity Solar dynamo Solar-terrestrial Sun Sunspots. The workings of the model may be seen in the accompanying movies and/or by using the software available via SpringerPlus' website, or on the Netlogo (TM) community website, where help is readable available, and should all these fail, some help from the author. The behavior of the agents' long- and short-range magnetic forces is discussed within this paper as well as the model's use of internal boundary conditions. This allows them to undertake two duties there: A) the B - L subsurface field spawns the next generation of new magnetic field via new agents, and B) the B - L subsurface field attracts lower-latitude fields via the "long-range" magnetic stress tension ii) nearby agents affect each other's motion by short-range interactions and iii) through annihilation: when opposite field agents get too close to each other, they disappear in pairs. There are but a few effects that agents have on each other: i) while at the poles, field agents are connected via the Babcock - Leighton (B - L) subsurface field to other latitudes. Our model predominantly focuses on spatial and temporal variations from the bulk fluid motions owing to magnetic interactions. The fluid motions generally advect the field with the well known meridional circulation and differential rotation. The individual agents are distinguished, for clarity, by various shades of blue and red arrows whose orientation indicates the direction the agents are moving, relative to the near-steady bulk fluid motions. ![]() The former carry a fixed amount of radially outward magnetic flux: 10(23) Mx, and the latter, the identical amount of inward directed flux. This model's entities consist of two breeds: blue and red agents. Our solar field mapping method uses Netlogo's cellular automata software via algorithms to carry out the movement of magnetic field on the Sun via agents. ![]() In particular, the model considers how photospheric fields evolve in time. This article focuses on mapping the Sun's large-scale magnetic fields. ![]()
