Vertical wind shear is one of the major influencing factors that inhibit tropical cyclone intensification. Large shears create asymmetries in cyclone vortex structure and its accompanying features (i.e., distribution of vertical velocity, cloud water, and rainfall). One of the most prominent theories describing the impact of shear on intensification states that in high shear environments the upper-level equivalent potential Vertical wind shear is one of the major influencing factors that inhibit tropical cyclone intensification. Large shears create asymmetries in cyclone vortex structure and its accompanying features (i.e., distribution of vertical velocity, cloud water, and rainfall). One of the most prominent theories describing the impact of shear on intensification states that in high shear environments the upper-level equivalent potential temperature maximum is vented from the cyclone center to the eyewall and the storm's minimum sea-level pressure subsequently rises through hydrostatic adjustment. Another prominent theory explains shear's impact by emphasizing the accompanying vortex tilt, which, through a thermal adjustment, causes warming near the TC center; this is thought to stabilize the cyclone. temperature maximum is vented from the cyclone center to the eyewall and the storm's minimum sea-level pressure subsequently rises through hydrostatic adjustment.
