Question

which statement best describes the function of a weather-forecasting algorithm?

a. large quantities of data collected from past and present meteorological events are compressed into smaller files.

b. current meteorological data is compared to that from the past to make predictions about future weather events.

c. files of compressed meteorological data are broken down into their original components and sizes.

d. algorithms are not used in weather forecasting.

Explanation:

• Option A: Weather - forecasting algorithms are not for compressing meteorological data. Their main task is prediction, not data compression.
• Option B: Weather - forecasting algorithms work by analyzing current meteorological data and comparing it with past data to predict future weather events. This is in line with the purpose of weather - forecasting algorithms.
• Option C: Decompressing data is not the function of a weather - forecasting algorithm. The algorithm is focused on prediction using data.
• Option D: Algorithms are widely used in weather forecasting for tasks like data analysis and prediction. So this statement is incorrect.

Answer:

B. Current meteorological data is compared to that from the past to make predictions about future weather events.
