Aviation Numerical Weather Prediction

Numerical weather prediction is based on the atmosphere being a(n):

• fluid

• gaseous medium

• isolated system

• layered series

Numerical weather prediction uses fluid dynamics and _____________ to estimate what the state of the atmosphere will be at a point in the future.

• Stoke's Theorem

• thermodynamic equations

• vector calculus

• gradients

Through the process of ___________, the model has a starting point in which to run variables that can hypothesize how a weather system may develop.

The five basic atmospheric variables that weather models evaluate within their primitive equations are zonal/meridional directionality, vertical/horizontal temperature, moisture, and:

• hydrostatic equilibrium (atmospheric pressure)

• continuity

• phase differentiation

• long & short wave patterns

___________ is a method that is used to replace and simplify processes that are too small in scale, or too complex, to be physically represented within the model data.

The two most common forms of parametrization are global and regional, and they depend upon __________ to determine the type.

The higher the resolution, the more _________ a forecast.

Models are considered high or low resolution based on the spacing of the grid points in ______________.

• SM

• NM

Vertical resolution is dependent upon how many ______ of the atmosphere analysis can be conducted on.

Grid point models focus their calculations at one particular point on a map and then _______ the remaining data between points.
