FIGURE 6.9.1.-The capture of a grain by a jet stream. The shaded area represents the jet stream. The orbit of a gram (thick curve) intersects the jet stream at a. Collisions lead to fragmentation and fragments are ejected mainly in orbits like 2, but some fragments may move in orbits like 1 or 3. All these orbits carry them back to the point a. Subsequent collision at a may lead to further fragmentation, but, if the collisions are at least partly inelastic, the final result is that all the fragments will be captured by the jet stream.
