Annular hurricanes have been simulated that have gone through the life cycle of an eyewall replacement. The simulations show that the major rainbands will grow such that the arms will overlap, and then it spirals into itself to form a concentric eyewall. The inner eyewall dissipates, leaving a hurricane with a singular large eye with no rainbands.
In most cases, the outer eyewall begins to contract soon after its formation, which chokes off the inner eye and leaves a much larger but more stable eye. While the replacement cycle tends to weaken storms as it occurs, the new eyewall can contract fairly quickly after the old eyewall dissipates, allowing the storm to re-strengthen.
Tropical cyclones can become annular as a result of eyewall mesovortices mixing the strong winds found in the eyewalls of storms with the weak winds of the eye, which helps to expand the eye. In addition, this process helps to make the equivalent potential temperature (often referred to as theta-e or θ e {\displaystyle \theta _{e}} ) within ...
A user's motor abilities, communication skills and needs, cognition and vision are assessed in order to determine the most appropriate match to a communication system. [72] Depending on the individual's physical status, recommendations of an alternative access method, a change in seating/positioning, a mounting system and/or communication aid ...
Pivotal response treatment is a naturalistic intervention model derived from the principles of applied behavior analysis.Rather than target individual behaviors one at a time, PRT targets pivotal areas of a child's development such as motivation, [3] responsiveness to multiple cues, [4] self-management, and social initiations.

Interpersonal communication research addresses at least six categories of inquiry: 1) how humans adjust and adapt their verbal communication and nonverbal communication during face-to-face communication; 2) how messages are produced; 3) how uncertainty influences behavior and information-management strategies; 4) deceptive communication; 5 ...
Example of basic PECS communication board. The Picture Exchange Communication System (PECS) is an augmentative and alternative communication system developed and produced by Pyramid Educational Consultants, Inc. [1] PECS was developed in 1985 at the Delaware Autism Program by Andy Bondy, PhD, and Lori Frost, MS, CCC-SLP. [2]
This activity gives students the chance to improve their communication skills in the TL in a low-pressure situation. Most students are more comfortable speaking in pairs rather than in front of the entire class. [4] Instructors need to be aware of the differences between a conversation and an utterance.
