What does TEMPO refer to in weather forecasting?

TEMPO in weather forecasting refers to temporary variations in weather conditions that are expected to last less than an hour. It is often used to denote short-lived weather phenomena, such as brief rain showers or gusty winds, that can impact conditions significantly but are not part of a longer-term trend.

This term is important for meteorologists who need to communicate immediate changes in weather to the public or specific sectors, such as aviation or outdoor events, where short-term weather impacts can be critical for safety and planning. Recognizing these temporary fluctuations is crucial in providing accurate forecasts and ensuring preparedness for sudden weather changes.

The other options pertain to broader weather phenomena: long-term weather patterns encompass overall climate trends; extreme weather events relate to significant occurrences like hurricanes or tornadoes; and seasonal climate changes refer to variations seen over longer periods, typically across seasons. Each of these terms represents a different aspect of weather and climate, highlighting the specific nature of TEMPO as indicative of short-lived, immediate changes.
