Final answer:
A cold front typically causes a sudden decrease in temperature, potentially dropping the temperature by 40.0°F, which equals a 22.2°C decrease.
Step-by-step explanation:
The type of front that most likely brings a sudden decrease in temperature is a cold front. When a cold front moves into an area, it pushes the warmer air upward abruptly, leading to a quick drop in temperature. This can often be accompanied by strong winds and intense weather conditions such as storms or heavy rain. For instance, a cold front could cause the temperature to plummet by 40.0 Fahrenheit degrees. In terms of temperature change, if there is a decrease of 40.0°F, it corresponds to a decrease of 22.2°C, calculated by the formula ΔF = (9/5)ΔC.
