Figure 11

Tracking statistics at 850 hPa to the rainy season (AMJJ) of 2006 (left column) and 2007 (right column). ((a), (d)) Genesis density scaled to number density per unit area (~10⁶ km²) per season, shading indicates values greater than 6. ((b), (e)) Track density per unit area (~10⁶ km²) per season, shading indicates values greater than 40. ((c), (f)) Lysis density per unit area (~10⁶ km²) per season, shading values are the same as in ((a), (d)).
