Westerly wind burst

[3] However, no concrete definition has been determined, with Tziperman and Yu (2007) defining them as having winds of 14 km/h (8.7 mph) and lasting "at least a few days".

[3] Recent studies, including Yu et al. (2003), have indicated some correlation between westerly wind bursts and the El Niño–Southern Oscillation (ENSO).

[1] For example, during July 2015 Typhoon Chan-hom and Cyclone Raquel developed simultaneously over the Northwestern and Southwestern Pacific, respectively, in conjunction with a westerly wind burst.

This was also the only known instance of twin cyclones during July and attributed to the record strength of the 2014–16 El Niño event.

[7] In May 2002, a strong westerly wind burst moved from west to east across the Indian Ocean, producing two separate sets of twin cyclones.
