Fig. 1: Increased tropical cyclone (TC) activities along the coasts of China in the second decaying summer ([JJA(2)], June-July-August) of double-year La Niña events.

From: China coasts facing more tropical cyclone risks during the second decaying summer of double-year La Niña events

Fig. 1

The difference of western North Pacific (WNP) TC track density (shading) and steering flow anomaly (vector; units: m/s) in decaying summer between single- and double-year La Niña events (double-year decaying summer [JJA(2)] minus single-year decaying summer [JJA(1)]). Red (black) contour line indicates the 5870 geopotential meter in the decaying summer of double-year (single-year) La Niña events, respectively. Black crosses and green vectors represent respectively the TC track density anomaly and steering flow anomalies being above the 95% confidence level based on Student’s t test.
