Typhoon Parma (left) and Melor (right) interacting with each other in the Philippine Sea on October 6, 2009.. The Fujiwhara effect, sometimes referred to as the Fujiwara effect, Fujiw(h)ara interaction or binary interaction, is a phenomenon that occurs when two nearby cyclonic vortices move around each other and close the distance between the circulations of their corresponding low-pressure areas.
The Fujiwhara effect – which describes the rotation of two storms around each other – is one of meteorology's most exquisite dances. It's most common with tropical cyclones such as typhoons or ...
A cluster of tropical activity has developed across the Pacific Ocean, as three features battle for dominance and hold the potential for a phenomenon called the Fujiwhara Effect to occur.
The cyclone will also distort in shape, becoming less symmetric with time. [17] [18] [19] During extratropical transition, the cyclone begins to tilt back into the colder airmass with height, and the cyclone's primary energy source converts from the release of latent heat from condensation (from thunderstorms near the center) to baroclinic ...
Bomb cyclone UCLA climate scientist Daniel Swain pointed to other unusual attributes of the weather system, including a "sting jet," or localized acceleration of winds next to a low-pressure center.
Knowledge of the beta effect can be used to steer a tropical cyclone, since it leads to a more northwest heading for tropical cyclones in the Northern Hemisphere due to differences in the coriolis force around the cyclone. [5] For example, the beta effect will allow a tropical cyclone to track poleward and slightly to the right of the deep ...
[48] [21] Other record-breaking rainfall events caused by tropical cyclones in Réunion include Cyclone Denise, which dropped 1,144 mm (45.0 in) of rain in 12 hours and 1,825 mm (71.9 in) in 24 hours at Foc Foc; an unnamed tropical cyclone in 1958 caused 2,467 mm (97.1 in) of rain to fall at Aurere; and Cyclone Gamede dropped 3,929 mm (154.7 in ...
- Sakuhei Fujiwhara is the first to note that hurricanes move with the larger scale flow, and later publishes a paper on the Fujiwhara effect in 1921. [40] 1920 – Milutin Milanković proposes that long term climatic cycles may be due to changes in the eccentricity of the Earth's orbit and changes in the Earth's obliquity.
