Numerical forecast models predict ________ weather phenomena using
A)parameterizations
B)assumptions
C)bias
D)the K-index

Question

Quizplus · Accepted Answer

Numerical forecast models use parameterizations, which are mathematical equations that simulate physical processes in the atmosphere, to predict weather phenomena. Assumptions are also made in the modeling process, but they are not the primary method of prediction. Bias is a term used to describe the difference between forecasted values and actual values, and the K-index is a measure of thunderstorm potential.
