There are several different methods
that can be used to create a forecast. The method a forecaster chooses depends
upon the experience of the forecaster, the amount of information available to
the forecaster, the level of difficulty that the forecast situation presents,
and the degree of accuracy or confidence needed in the forecast.
The first of these methods is the persistence method; the simplest way of
producing a forecast. The persistence method assumes that the conditions at the
time of the forecast will not change. For example, if it is sunny and 87 degree
today, the persistence method predicts that it will be sunny and 87 degree
tomorrow. If two inches of rain fell today, the persistence method would predict
two inches of rain for tomorrow. However, if weather conditions change
significantly from day to day, the persistence method usually bre A. (A) Imagination of the forecaster. B. (C) Necessary amount of information. C. (B) Practical knowledge of the forecaster. D. (D) Degree of difficulty involved in forecasting.

The trends method involves determining the speed and direction of move A. it makes predications about weather. B. it makes predications about precipitation.
