Which of these events can weaken a hurricane?

Passing over cool water stirred up by an earlier storm
Sinking of warm, dry air at the storm's center
Intensification of updrafts in the eyewall
A decrease in strong wind shear between the storm's upper and lower halves

Correct Answer

A. Passing over cool water stirred up by an earlier storm

Explanation

Passing over cool water stirred up by an earlier storm can weaken a hurricane. Hurricanes require warm water to sustain their strength, so when a hurricane passes over cool water, it loses its main source of energy. Additionally, if the water has been stirred up by an earlier storm, it can disrupt the hurricane's structure and cause it to weaken further.

Satellites can collect data about the environment by detecting types of electromagnetic radiation that are not visible to the human eye.

True
False

Correct Answer

A. True

Explanation

Satellites have the ability to detect various types of electromagnetic radiation that are not visible to the human eye, allowing them to collect data about the environment. This is true because satellites are equipped with sensors and instruments that can detect different wavelengths of radiation, such as infrared and microwave, which provide valuable information about the Earth's surface, atmosphere, and climate. By analyzing this data, scientists can gain insights into various environmental factors and phenomena, making satellites an essential tool for environmental monitoring and research.

Why are different terms, such as hurricane, typhoon, and cyclone, used for hurricane-like storms?

The different terms indicate a different minimum wind speed.
Each term indicates a different level of storm damage
The different terms indicate differences in how each storm forms.
Different terms are used in different parts of the world

Correct Answer

A. Different terms are used in different parts of the world

Explanation

The different terms, such as hurricane, typhoon, and cyclone, are used for hurricane-like storms because they vary based on the geographic location. Different parts of the world use different terms to refer to these storms. For example, hurricanes are used in the Atlantic and Northeast Pacific, typhoons are used in the Northwest Pacific, and cyclones are used in the South Pacific and Indian Ocean. This is done to differentiate and classify these storms based on their regional occurrence.

Which of these is most likely to be added to a satellite image after a satellite has collected data about a hurricane?

Lines showing state and country boundaries
A photograph of the hurricane taken from an airplane
Bright areas showing where clouds are expected to be
A legend showing the height of the satellite above Earth`s surface

Correct Answer

A. Lines showing state and country boundaries

Explanation

Lines showing state and country boundaries are most likely to be added to a satellite image after data about a hurricane has been collected. This is because the lines indicating state and country boundaries provide important geographical context to the satellite image, allowing viewers to identify the location and extent of the hurricane in relation to specific regions and countries. This information is valuable for understanding the potential impact and tracking of the hurricane.

What occurs where a hurricane's rainbands are forming?

Light precipitation is falling
Moist air is rising
Wind Shear is increasing
Surface air pressure is decreasing

Correct Answer

A. Moist air is rising

Explanation

When a hurricane's rainbands are forming, moist air is rising. This is because the warm ocean surface heats the air, causing it to become less dense and rise. As the moist air rises, it cools and condenses, forming clouds and precipitation. This rising motion of moist air is a key process in the development and intensification of a hurricane.

Which of these is MOST likely to be added to a satellite image after a satellite was collected data about a hurricane?

A photograph of the hurricane taken from an airplane
Bright areas showing where clouds are expected to be
A legend showing the height of the satellite above Earth's surface
Lines showing state and country boundaries

Correct Answer

A. Lines showing state and country boundaries

Explanation

Lines showing state and country boundaries are most likely to be added to a satellite image after data about a hurricane is collected. This is because adding such lines would provide geographical context and help identify the specific locations affected by the hurricane. It would allow viewers to understand the boundaries of different regions and countries within the satellite image, aiding in the analysis and interpretation of the hurricane's impact on specific areas.

The spiraling pattern of winds in a hurricane is produced by high wind shear over tropical ocean waters.

True
False

Correct Answer

A. False

Explanation

The spiraling pattern of winds in a hurricane is not produced by high wind shear over tropical ocean waters. In fact, wind shear can disrupt and weaken hurricanes. The spiraling pattern of winds in a hurricane is primarily caused by the Earth's rotation, known as the Coriolis effect. This effect causes the winds to rotate around a low-pressure center, creating the characteristic spiral shape of a hurricane. Therefore, the correct answer is false.

Which of the following is the correct order of the stages leading to the development of a hurricane?

Easterly wave --> tropical disturbance --> tropical depression --> tropical storm
Tropical disturbance --> easterly wave --> tropical storm --> tropical depression
Tropical storm --> tropical depression --> easterly wave
Tropical depression --> tropical storm --> tropical storm --> easterly wave

Correct Answer

A. Easterly wave --> tropical disturbance --> tropical depression --> tropical storm

Explanation

The correct order of the stages leading to the development of a hurricane is easterly wave --> tropical disturbance --> tropical depression --> tropical storm. This is because an easterly wave is a low-pressure system that moves from east to west and can serve as a precursor to the formation of a tropical disturbance. A tropical disturbance is an organized system of thunderstorms with a defined circulation. If the disturbance strengthens and its winds reach a certain threshold, it becomes a tropical depression. As the depression continues to intensify, it can develop into a tropical storm, which is characterized by stronger winds and a well-defined circulation.

How does Doppler radar differ from standard weather radar?

Doppler radar can locate clouds.
Doppler radar shows areas of precipitation.
Doppler radar can measure wind speed and direction within a storm.
Dopplar radar can be used on hurricane-hunter aircraft.

Correct Answer

A. Doppler radar can measure wind speed and direction within a storm.

Explanation

Doppler radar differs from standard weather radar because it has the capability to measure wind speed and direction within a storm. Standard weather radar typically shows areas of precipitation and can locate clouds, but it does not provide information about the wind within a storm. Doppler radar uses the Doppler effect to detect the movement of precipitation particles and can calculate the speed and direction of the wind based on the frequency shift of the radar waves. This information is crucial for understanding the intensity and movement of a storm system.

An encounter with the Saharan Air Layer can affect a hurricane in all of these ways EXCEPT by

Mixing dry air into the hurricane.
Interrupting the hurricane`s updrafts.
Producing strong wind shear that can tear apart the hurricane.
Increasing the transfer of heat energy from the ocean to the hurricane.

Correct Answer

A. Increasing the transfer of heat energy from the ocean to the hurricane.

Explanation

The Saharan Air Layer can affect a hurricane by mixing dry air into the storm, interrupting its updrafts, and producing strong wind shear that can tear it apart. However, it does not increase the transfer of heat energy from the ocean to the hurricane.

Which of the following statements explains why hurricane-strength tropical cyclones in the Pacific Ocean rarely strike California?

Intense tropical cyclones are uncommon in the Pacific Ocean
A cold ocean current off the coast decreases their intensity
The Saharan Air Layer increases their wind shear
Their direction of rotation prevents them from moving eastward

Correct Answer

A. A cold ocean current off the coast decreases their intensity

Explanation

A cold ocean current off the coast of California decreases the intensity of hurricane-strength tropical cyclones in the Pacific Ocean. This cold current acts as a barrier, preventing warm ocean waters from fueling and intensifying the cyclones. As a result, the cyclones weaken and are less likely to strike California.

Suppose that a hurricane is headed toward the Atlantic coast of the U.S.. Which of these events would be likely to prevent landfall?

Prevailing winds steer the hurricane to the northwest
The hurricane passes over an area of warmer water
Updrafts of warm, moist air intensify inside the hurricane
The intensity of rainfall from the hurricane increases

Correct Answer

A. Prevailing winds steer the hurricane to the northwest

Explanation

Prevailing winds steer the hurricane to the northwest. This explanation is based on the fact that hurricanes in the Northern Hemisphere generally move from east to west, and prevailing winds from the northeast would push the hurricane away from the Atlantic coast of the U.S. If the hurricane is steered to the northwest, it would be less likely to make landfall on the coast.
