Origin of the Disturbance
Thunderstorm clouds gave birth to the tornado that swept through Manila. In turn, the thunderstorm was generated by the southwest monsoon. The monsoon is a seasonal reversal of winds. During the summer months, the southwest monsoon blows to the northeast.
A waterspout was created by thunderstorm clouds over Manila Bay. When the waterspout moved onto land, it became a tornado.
This was not as intense as those that form over North America. As a result, it was described as being similar to a mesocyclone. Mesocyclones are short lived phenomena that can give rise to more intense tornadoes.
A mesocyclone struck Manila in 2012 and caused heavy rains and strong winds. The recently observed tornado damaged a hundred homes and businesses before dissipating.
