Hurricanes begin as tropical cyclones that form over ​ (a)   ocean water. Energy in the form of heat is transferred to the air just above the ocean surface. This warm ​ (b)   air then rises.The energy in this rising air is released when the water vapor in it ​ (c)   to form clouds. This energy is released rapidly causing a ​ (d)   in the air pressure. Cooler air now swirls in from all sides. Tropical cyclones are known by different names depending on their ​ (e)   .

This image shows the tracks of historical tropical cyclones in the Atlantic Ocean and the eastern North Pacific Ocean. Which of the following problems might a researcher define based on information and observations of previous tropical cyclones?

• People living in the Central Plains region need to be prepared for tropical storms.

• People living along the coast in the Pacific Northwest need to be prepared for tropical storms.

• People living along the Gulf Coast and the Atlantic Ocean need to be prepared for tropical storms.

• Tropical storms only affect regions within a few miles of the coast, so they pose little threat to those living inland.

Which statement explains how energy is conserved in a tropical cyclone system?

• Energy is created as the oceans absorb sunlight near the equator and is destroyed as tropical cyclones move toward the poles.

• Sunlight absorbed by the oceans is transformed into thermal energy and kinetic energy and is transferred to other areas and objects as the tropical cyclone moves.

• Energy transferred from the oceans to the atmosphere is destroyed as tropical cyclones fade away

• Energy that enters the atmosphere through evaporation is destroyed as tropical cyclones fade away.

Analyze the diagram. Which statement explains how energy flows through the tropical cyclone system?

• Warm ocean water is transformed into rising columns of humid air and then transferred into the kinetic energy of wind.

• Thermal energy is transferred from the ocean water to the humid air, and the kinetic energy of the warm air causes wind.

• Thermal energy is transferred from the dry air to the ocean water and then transformed into the kinetic energy of waves.

• Cool ocean water is transformed into sinking columns of dry air and then transferred into the kinetic energy of waves.

This drawing represents a tropical cyclone system in the Northern Hemisphere. How would you develop a model, like this drawing, to represent the movement of air around a tropical cyclone in the Southern Hemisphere?

• Draw the larger set of arrows pointing toward the low pressure, and the smaller set of arrows spinning in a clockwise direction.

• Draw the larger set of arrows pointing toward the low pressure, and the smaller set of arrows spinning in a counterclockwise direction.

• Draw the larger set of arrows pointing away from the low pressure, and the smaller set of arrows spinning in a clockwise direction.

• Draw the larger set of arrows pointing away from the low pressure, and the smaller set of arrows spinning in a counterclockwise direction.

When certain interactions of the hydrosphere and atmosphere such as temperature and pressure occur over a tropical ocean, a tropical cyclone begins to form. The storm may be called a hurricane or a typhoon, depending on where it is located. As the cyclone forms and becomes increasingly intense, it passes through a series of stages. How can each stage be put into a pattern of interactions that describes how a cyclone is formed?

• Released energy drives winds until they reach very high speeds.

• A low-pressure area meets warm, moist ocean air.

• As water condenses into droplets, rain falls, and energy is released.

• Rising air cools and condenses.

• Warm, moist air rises, forming a low-pressure area underneath.

Which of the following questions might a weather researcher ask when trying to make predictions about a tropical cyclone that may be forming based on past observations and collected information? Select all that apply. Select three

• Are there nearby landmasses in this area?

• Have other tropical cyclones formed in this area?

• Do people need more fresh water to fall on their area?

• What is the temperature of the ocean water in this area?

• Are there forests nearby with few clearings and younger trees?
