熱帯収束帯
Tropical Depression Five-E formed out of a weak tropical wave, associated with scattered convection, which formed off the coast of Africa on June 23. The wave was moving towards the west at the rate of 23 mph (37 km/h), due to an area of high pressure located over the north-central Atlantic Ocean leading to a prevailing easterly flow. Some cyclonic turning was noted and convection was on either side of the axis— the center of the storm—but was mainly in association with the Intertropical Convergence Zone (ITCZ). The wave remained very close to the intertropical convergence zone for the next several days without any further development.
