What does the term 'intermittent variations' refer to in weather forecasts?

The term 'intermittent variations' in weather forecasts refers to frequent fluctuations in forecasted weather conditions. This means that the weather can change periodically, exhibiting different characteristics over a certain time frame. These variations do not imply a steady or consistent weather condition but rather indicate that the forecast can show a mix of elements like sunshine, rain, wind, or temperature changes at different times.

The other choices do not accurately capture the essence of 'intermittent variations.' Weather changes that last longer than TEMPOs suggest prolonged shifts rather than the frequency implied by intermittent variations. Improvements in weather conditions might occur, but intermittent variations encompass a broader scope, including both positive and negative weather changes. Lastly, constantly stable weather conditions are the opposite of what 'intermittent variations' signifies, as they would not involve fluctuations at all. Thus, understanding intermittent variations helps meteorologists communicate the likelihood and frequency of changing weather conditions effectively.
