The formation of these entities has been linked to the Madden-Julian oscillation and Rossby waves.
The formation of these entities has been linked to the Madden-Julian oscillation and Rossby waves. Two of these approach each other and eventually merge in the Fujiwara effect. Often re-curving around the subtropical ridge, their activity peaks in late summer. Reaching a 12 on the Beaufort scale, they rarely form near the equator because the Coriolis force there is too weak to make them spin. These systems are ranked by the Saffir-Simpson scale, on a scale from category 1 to category 5. For 10 points, name these rotating storm systems featuring a low-pressure central "eye," historical examples of which include Andrew, Rita, Wilma, and Katrina.
