  2. Eyewall replacement cycle - Wikipedia

    en.wikipedia.org/wiki/Eyewall_replacement_cycle

    Observations show that an eyewall replacement cycle can lead to the development of an annular hurricane. While some hurricanes develop into annular hurricanes without an eyewall replacement, it has been hypothesized that the dynamics leading to the formation of a secondary eyewall may be similar to those needed for development of an annular eye ...

  3. Annular tropical cyclone - Wikipedia

    en.wikipedia.org/wiki/Annular_tropical_cyclone

    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 ...

    Hurricane Rita underwent eyewall replacement while in the Gulf of Mexico where the storm went from a category 5 on the Saffir-Simpson Hurricane Wind Scale to a category 3 storm by landfall. [5] RAINEX flights into Hurricane Rita occurred on September 20, 21, 22, and 23, 2005.

  5. Mesovortex - Wikipedia

    en.wikipedia.org/wiki/Mesovortex

    An eyewall mesovortex is a small-scale rotational feature found in an eyewall of an intense tropical cyclone. Eyewall mesovortices are similar, in principle, to small "suction vortices" often observed in multiple-vortex tornadoes. In these vortices, wind speed can be up to 10% higher than in the rest of the eyewall.

    en.wikipedia.org/wiki/Interactive_Scenario_Builder

    Interactive Scenario Builder (Builder) is a modeling and simulation, three-dimensional application developed by the Advanced Tactical Environmental Simulation Team (ATEST) at the Naval Research Laboratory (NRL) that aids in understanding radio frequency (RF) and electro-optical/infrared (EO/IR) propagation.

  8. Live, virtual, and constructive - Wikipedia

    en.wikipedia.org/wiki/Live,_virtual,_and...

    Live, Virtual, & Constructive (LVC) Simulation is a broadly used taxonomy for classifying Modeling and Simulation (M&S). However, categorizing a simulation as a live, virtual, or constructive environment is problematic since there is no clear division among these categories.

  9. Dynamic simulation - Wikipedia

    en.wikipedia.org/wiki/Dynamic_simulation

    Dynamic simulation (or dynamic system simulation) is the use of a computer program to model the time-varying behavior of a dynamical system. The systems are typically described by ordinary differential equations or partial differential equations. A simulation run solves the state-equation system to find the behavior of the state variables over ...
