Weather Patterns

Is there a pattern in the relationship between starting air temperature and parcel height? Check your Simulating Rainstorms worksheet.

• Yes, the higher starting air temperature means the higher the parcel height.

• No, there is no relationship between starting air temperature and parcel height.

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.

What do the yellow arrows represent in the image?

• Air parcel LOSING energy as it rises in the troposphere and cools.

• Air parcel GAINING energy as it lowers in the troposphere and warms.

• Air parcel GAINING energy as it rises in the troposphere and cools.

• Air parcel LOSING energy as it lowers in the troposphere and warms.

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 the air parcel moved higher, it lost more energy.

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

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