[meteorite-list] strewnfield size vs entry angle

Where a meteorite results from an object that experiences a single fragmentation event (which presumably describes most cases), the strewn field is not strongly related to the entry details, but is instead defined by the wind conditions at the time. After the fragmentation, the debris is initially stretched out along the axis of flight, with heavier components carrying further forward. But this forward momentum is quickly lost, and the pattern can change considerably during several minutes of cold flight. Tail winds compress the size of the field, head winds stretch it out, and any wind component at an angle to the entry path broadens and tilts the field. Multiple fragmentation events produce multiple strewn fields, although they may overlap and be recognized only as a single distribution.
