Select the correct answer.
Andrea plans to go fishing in the morning, so she checks the weather forecast. The forecast shows a high-pressure area forming near her fishing spot. Using the weather data below, predict the possible weather conditions for Andrea's trip.
| Time (a.m.) | Temperature ($^{\circ} C$) | Pressure (mb) |
| :---------- | :-------------------------- | :------------ |
| 7.00 | 14 | 995 |
| 8.00 | 14 | 1001 |
| 9.00 | 14 | 1113 |
| 10.00 | 15 | 1120 |
A. cloudy skies with minimal precipitation
B. clear skies with minimal precipitation
C. cloudy skies with moderate precipitation
D. clear skies with heavy precipitation
Answer (2)
High-pressure systems are forming near Andrea's fishing spot.
High-pressure systems are associated with clear skies and minimal precipitation.
Predict the weather conditions for Andrea's fishing trip.
The correct answer is \boxed{B}.
Explanation
Understanding the Problem We want to predict the weather conditions for Andrea's fishing trip based on the weather forecast, which indicates a high-pressure area forming near her fishing spot. The weather data shows that the pressure is increasing from 995 mb at 7:00 a.m. to 1120 mb at 10:00 a.m.
Relating High Pressure to Weather High-pressure systems are generally associated with stable atmospheric conditions, which typically lead to clear skies and minimal precipitation. This is because high pressure causes air to descend, which inhibits cloud formation and precipitation.
Predicting Weather Conditions Based on the relationship between high-pressure systems and weather conditions, we can predict that Andrea's fishing trip will likely have clear skies with minimal precipitation.
Selecting the Correct Answer Therefore, the correct answer is B. clear skies with minimal precipitation.
Examples
Understanding the relationship between atmospheric pressure and weather conditions is crucial in many real-life scenarios. For example, farmers use weather forecasts to plan their planting and harvesting schedules, as high-pressure systems often bring stable weather suitable for these activities. Similarly, pilots rely on accurate weather predictions to ensure safe flights, as high-pressure areas can indicate favorable flying conditions. Even everyday activities like planning a picnic or a day at the beach benefit from knowing whether a high-pressure system will bring sunny skies or if a low-pressure system might bring rain.
The weather forecast indicates a high-pressure area forming near Andrea's fishing spot, which typically results in clear skies and minimal precipitation. Given this information and the rising pressure readings, it is likely that Andrea will experience favorable weather conditions for fishing. Therefore, the chosen answer is B. clear skies with minimal precipitation.
