WebFeb 22, 2024 · A Secondary Eyewall Formation (SEF) is characterized by the formation of a new eyewall outside the primary eyewall. An Eyewall Replacement Cycle (ERC) is one in which the inner eyewall is replaced by the outer eyewall. SEF/ERC are common phenomena in a mature TC.

WebThis study examines the predictability and dynamics of tropical cyclone (TC) secondary eyewall formation (SEF), eyewall replacement cycles (ERC) and intensity changes under moderate... In meteorology, eyewall replacement cycles, also called concentric eyewall cycles, naturally occur in intense tropical cyclones, generally with winds greater than 185 km/h (115 mph), or major hurricanes (Category 3 or above). When tropical cyclones reach this intensity, and the eyewall contracts or is already … See more The first tropical system to be observed with concentric eyewalls was Typhoon Sarah by Fortner in 1956, which he described as "an eye within an eye".
