Over millennia, orbits in the Taurid meteoroid complex precess under the gravitational influence of Jupiter, changing their orientation in 3-dimensional space. There are four possible orientations allowing Earth intersection, as shown in the diagrams. The Northern and Southern Taurids produce night-time meteors in October--November (the Northern descending and the Southern ascending through the ecliptic at the point where they reach the Earth's orbit). The two corresponding daytime branches occur after the meteoroids have passed perihelion.
