AbstractA flight-level aircraft dataset consisting of 79 Atlantic basin hurricanes from 1977 to 2007 was used to develop an unprecedented climatology of inner-core intensity and structure changes associated with eyewall replacement cycles (ERCs). During an ERC, the inner-core structure was found to undergo dramatic changes that result in an intensity oscillation and rapid broadening of the wind field. Concentrated temporal sampling by reconnaissance aircraft in 14 of the 79 hurricanes captured… 
Reducing Operational Hurricane Intensity Forecast Errors during Eyewall Replacement Cycles
AbstractEyewall replacement cycles (ERCs) are fairly common events in tropical cyclones (TCs) of hurricane intensity or greater and typically cause large and sometimes rapid changes in the intensity
Outer vortex wind structure changes during and following tropical cyclone secondary eyewall formation in the Atlantic
ABSTRACT Some recent studies have utilized flight-level (700 mb) winds to document the maximum wind speeds (Vmax) and radius of Vmax (Rmax) of the original and secondary eyewalls during 24 Atlantic
Hurricane Bonnie (1998): Maintaining Intensity during High Vertical Wind Shear and an Eyewall Replacement Cycle
Hurricane Bonnie (1998) was an unusually resilient hurricane that maintained a steady-state intensity while experiencing strong (12–16 m s−1) vertical wind shear and an eyewall replacement cycle.
Repeated Eyewall Replacement Cycles in Hurricane Frances (2004)
Hurricane Frances (2004) represented an unusual event that produced three consecutive overlapping eyewall replacement cycles (ERCs). Their evolution followed some aspects of the typical ERC. The
Predicting Hurricane Intensity and Structure Changes Associated with Eyewall Replacement Cycles
AbstractEyewall replacement cycles are commonly observed in tropical cyclones and are well known to cause fluctuations in intensity and wind structure. These fluctuations are often large and rapid
Airborne Doppler Observations of the Inner-Core Structural Differences between Intensifying and Steady-State Tropical Cyclones
AbstractDifferences in the inner-core structure of intensifying [IN; intensity increase of at least 20 kt (24 h)−1, where 1 kt = 0.51 m s−1] and steady-state [SS; intensity remaining between ±10 kt

The Structure and Evolution of Hurricane Elena (1985). Part I: Symmetric Intensification
Abstract One of the most complete aircraft reconnaissance and ground-based radar datasets of a single tropical cyclone was recorded in Hurricane Elena (1985) as it made a slow, 3-day anticyclonic
Annular Hurricanes
This study introduces and examines a symmetric category of tropical cyclone, which the authors call annular hurricanes. The structural characteristics and formation of this type of hurricane are
