Weather Patterns

Day 1 and Day 2 in Greenville started with the same amount of water vapor in the air parcels there. It rained at the end of Day 2 but it did not rain at the end of Day 1.

What could have happened to the air parcel to cause rainfall on Day 2?

• The air parcel was warmer than the surrounding air, so it gained energy.

• The air parcel was warmer than the surrounding air, so it lost energy.

• The air parcel was at the same low temperature as the surrounding air, so it had low energy.

• The air parcel was cooler than the surrounding air, so it gained energy.

There were two rainstorms in Marion last month. Before Storm 1, Marion’s temperature at the surface was 26°C. Before Storm 2, the air temperature at the surface was 14°C. The temperature of areas surrounding Marion was the same before both storms.

Which storm is likely to have had more rainfall?

• Storm 1. The air parcel at the surface was warmer and had more energy, so when it moved higher, it lost more energy.

• Storm 1. The air parcel at the surface was warmer and had more energy, so when cooler air from above came down, it lost more energy.

• Storm 2. The air parcel at the surface was cooler and had less energy, so when it moved higher, it gained more energy.

• Storm 2. The air parcel at the surface was cooler and had less energy, so with low energy it remained near the surface.

On two consecutive days in Springfield, the air parcels started with the same humidity levels. On Day 1, the temperature was 30°C, and on Day 2, it was 20°C. It rained on Day 1 but not on Day 2.

What could explain the rainfall on Day 1?

• The air parcel on Day 1 was cooler and stayed near the surface, preventing condensation.

• The air parcel on Day 2 was cooler and stayed near the surface, preventing condensation.

• The air parcel on Day 2 was warmer and rose higher, cooling and condensing more moisture.

• The air parcel on Day 1 was warmer and rose higher, cooling and condensing more moisture.

In Rivertown, two storms occurred last week. Before Storm A, the surface temperature was 18°C, and before Storm B, it was 25°C. The surrounding areas had the same temperature before both storms.

Which storm likely resulted in more intense rainfall?

• Storm B. The warmer air parcel had less energy, leading to less rainfall.

• Storm B. The warmer air parcel had more energy, leading to more rainfall.

• Storm A. The cooler air parcel had more energy, leading to more rainfall.

• Storm A. The cooler air parcel had less energy, leading to less rainfall.

During a weather study, two air parcels in Lakeview had the same initial humidity. On Day X, the temperature was 22°C, and on Day Y, it was 28°C. Rainfall was observed on Day Y but not on Day X.

What could have caused the rainfall on Day Y?

• The air parcel on Day X was warmer, causing it to rise and condense more moisture.

• The air parcel on Day Y was warmer, causing it to rise and condense more moisture.

• The air parcel on Day X was cooler, causing it to rise and condense more moisture.

• The air parcel on Day Y was cooler, causing it to rise and condense more moisture.

There were two rainstorms in Sinan last month. Before Storm 1, Sinan’s temperature was 30°C. Before Storm 2, the temperature was 15°C. Before both storms, the temperature of the surrounding areas was the same and wind was blowing toward Sinan. There was the same amount of water vapor before Storm 1 and Storm 2.

Which storm likely had more rainfall?

• Storm 2. The cooler air parcel had less energy at the surface, so when wind pushed it higher, it gained more energy.

• Storm 2. Wind caused cooler air from above the air parcel to move down, causing the air parcel at the surface to lose more energy.

• Storm 1. Wind pushed more water vapor out of the warmer air parcel.

• Storm 1. Wind pushed the warmer air parcel even higher and the air parcel lost more energy.
