Figure 8

Lagged composite maps of filtered OLR anomaly (W·m⁻²; shaded) and sigma-level 0.21 velocity potential (black contours every 0.75 × 10⁶·m²·s⁻¹; negative values are dashed) for a frequency band of 20 to 96 days. Composites are centered on day −12 to day +9 in which day 0 represents the most intense precipitation events over SP region (June 06). (a) Day −12 (May 25), (b) Day −9 (May 28), (c) Day −6 (May 31), (d) Day −3 (Jun 03), (e) Day 0 (Jun 06), (f) Day +3 (Jun 09), (g) Day +6 (Jun 12), and (h) Day +9 (Jun 15).
