The forecasting time horizon that would typically be easiest to predict would be:

a. Medium-range

b. Long-range

c. Short-range

d. Intermediate range

Answer: c. Short-range

In these cases, there is the possibility to make seasonal forecasts easily for the next three-month time horizon. Weather that is forecast for a short time span usually covers a period that is not too long stretching from one day to several months.

Tendency to come to a correct conclusion over a shorter term or period is more accurate and reliable as the number of unknown factors and external forces to affect it is little and limited. Temporary forecasts make use of data that is quickly available, recent patterns, and the present situation, which usually is more stable and predictable because they easily extrapolate past observed data.

Conversely, medium-range, long-range, and intermediate-range forecasts run for longer time periods, which makes them be more vulnerable to various unknowable events, various changes in market conditions, and any inconsistent disruptions. The air forecast goes further into the future, it becomes even more uncertain and the more challenging the prediction is.

The forecast horizons over which these predictions are made are key distinguishing characteristics of short-range and long-range forecasts. In this regard, short-range forecasts rely on more immediate, limited-time data and are therefore often regarded as easier to make with reasonable accuracy compared to long-range forecasts.
