Atmospheric dynamics is the study of the forces that result in the changing motions of air within the Earth's atmosphere. The equations of motion can be expressed in either an Eulerian or Lagrangian form, i.e.
Dynamics - Generally, any forces that produce motion or affect change. In operational meteorology, dynamics usually refer specifically to those forces that produce vertical motion in the atmosphere.

DYNAMICS A branch of mechanics that deals with forces and their relations to patterns of motion. In metorology, this relates especially to wind and water patterns.

DYNAMICS- Refers to upward forcing caused by a mechanism that forces the air to rise or sink such as thermal advection, jet streak divergence and PDVA
EASTERLY WAVE- An inverted trough in the tropics that moves with the tropical easterlies.

THERMODYNAMICS Study of the processes that involve the transformation of heat into mechanical work, of mechanical work into heat, or the flow of heat from a hotter body to a colder body.
DYNAMICS - The study of physics where motion and acceleration is involved (work is done).
DYNAMIC FETCH - Wave-generating winds over a body of water in-phase with the movement of that region of winds. See also TRAPPED FETCH.
The dynamics of such systems are not fully understood, and it is only with the (recent) arrival of very high-resolution satellite imagery & sensors in a wide variety of spectral bands that the detail within such systems can be studied.
Thermodynamics The branch of physics that deals with the relationship between heat and work. 2. Heat Is a form of energy that reslults from the motion of molecules in a substance.
In ocean dynamics, the upward motion of sub-surface water toward the surface of the ocean. This is often a source of cold, nutrient-rich water. Strong upwelling occurs along the equator where easterly winds are present.
Temperature In thermodynamics, the integrating factor of the differential equation referred to as the first law of thermodynamics. In statistical mechanics, a measure of translational molecular kinetic energy (with three degrees of freedom).

dissipation - (Also called viscous dissipation.) In thermodynamics, the conversion of kinetic energy into internal energy by work done against the viscous stresses. Sometimes the rate of conversion per unit volume is meant.
Hurricane Model: The Geophysical and Fluid Dynamics Laboratory(GFDL) developed the hurricane model in order to improve hurricane landfall forecasts. The hurricane model is centered on the eye of the hurricane for each run of the model.
Cold Air Damming often implies that the trapped cold air mass is influencing the dynamics of the overlying air mass, e.g. in an overrunning scenario.
Any hydrodynamics text will explain this in detail. It is the second term that makes the equations of motion nonlinear, and introduces so much difficulty into hydrodynamics.
In this case, the effects of ambient atmospheric dynamics and thermodynamics on storm type are included. The information in the diagram is subjective, and we cannot assign absolute shear and stability values as partitions between storm types.
In dynamics, it is that part of the stress tensor that is independent of viscosity and depends only upon the molecular motion appropriate to the local temperature and density.
