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 lost energy.

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

Rochelle had two rainstorms in February. Storm 1 had more rainfall than Storm 2. The temperature of the surrounding areas was the same before both storms. What conditions could have caused Storm 1 to have more rainfall than Storm 2? Before Storm 1, Rochelle could have been:

• warmer than before Storm 2 and windy. Wind pushed more water vapor out of the warmer air parcel.

• warmer than before Storm 2 and windy. Wind pushed the warmer air parcel even higher and the air parcel lost more energy.

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

• cooler than before Storm 2 and windy. Wind pushed the cooler air parcel even higher and the air parcel gained more energy.

Air Parcel 1 is the same temperature as the surrounding air. Air parcel 2 is warmer than the surrounding air. Air Parcel 1 and Air Parcel 2 started with the same amount of water vapor in them. Which air parcel will have more rainfall and why?

• Both air parcels will have the same amount of rain. They have the same surrounding air temperature, so the same amount of water vapor will fall as rain.

• Air Parcel 1 is colder than Air Parcel 2, so more water vapor will fall as rain.

• Air Parcel 2 will gain energy from the surrounding air, which will cause more water vapor to fall as rain.

• Air Parcel 2 will lose energy to the surrounding air, which will cause more water vapor to fall as rain.

The town of San Angelo had two rainstorms in July. Storm 1 had more rainfall than Storm 2. The temperature of the surrounding areas was the same before both storms. What could explain why Storm 1 had more rainfall than Storm 2?

Before Storm 1, the air parcel at the surface could have been:

• warmer, so when the air parcel moved higher, it lost more energy.

• warmer, so when cooler air from above moved down, it lost more energy.

• cooler, so when the air parcel moved higher, it gained more energy.

• cooler, so the air parcel had low energy and remained near the surface.

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 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.

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

Day 1 and Day 2 in Kokomo started with the same amount of water vapor in the air parcels over Kokomo. It rained at the end of Day 1 but it did not rain at the end of Day 2. What could have happened to the air parcel to cause rainfall on Day 1?

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

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

There were two rainstorms in Chateh last month. Before Storm 1, Chateh’s temperature at the surface was 19°C. Before Storm 2, the air temperature at the surface was 28°C. The temperature of areas surrounding Chateh was the same before both storms. Which storm likely had more rainfall?

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

• Storm 1. The air parcel at the surface was cooler and had less energy, so with low energy it remained near the surface.

• Storm 2. 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 warmer and had more energy, so when it moved higher, it lost more energy.

Jamestown had two rainstorms in July. Storm 2 had more rainfall than Storm 1. The temperature of the surrounding areas was the same before both storms. What could have caused Storm 2 to have more rainfall than Storm 1? Before Storm 2, Jamestown could have been:

• cooler than before Storm 1 and windy. Wind pushed the cooler air parcel even higher and the air parcel gained more energy.

• cooler than before Storm 1 and windy. Wind caused the cooler air from above the air parcel to move down, causing the cooler air parcel at the surface to lose more energy.

• warmer than before Storm 1 and windy. Wind pushed more water vapor out of the warmer air parcel.

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

Air Parcel 1 is warmer than the surrounding air. Air Parcel 2 is at the same

temperature as the surrounding air. Air Parcel 1 and Air Parcel 2 started with the

same amount of water vapor in them. Which air parcel will have more rainfall and why?

• Both air parcels will have the same amount of rain. They have the same surrounding air temperature, so the same amount of water vapor will fall as rain.

• Air Parcel 1 will lose more energy to the surrounding air, which will cause more water vapor to fall as rain.

• Air Parcel 1 will gain energy from the surrounding air, which will cause more water vapor to fall as rain.

• Air Parcel 2 is colder than Air Parcel 1, so more water vapor will fall as rain.
