Question 1

Which of the following is the least likely characteristic of an easterly wave?

Accepted Answer

An easterly wave typically has diverging winds on its western side, not converging winds.

Question 2

Hurricanes have strong divergence at their tops.

Accepted Answer

Hurricanes have a strong upward movement of air at the center, which causes strong divergence at the tops of the hurricanes. This divergence leads to the formation of a clear eye at the center of the storm.

Question 3

The ocean surface water temperature is usually cooler after the passage of a hurricane.​

Accepted Answer

Hurricanes often bring up cooler water from deeper in the ocean to the surface, which causes a decrease in surface water temperature.

Question 4

Suppose this year five tropical storms develop into full-fledged hurricanes over the North Atlantic Ocean.The name of the third hurricane will definitely begin with the letter C.

Accepted Answer

The answer of Suppose this year five tropical storms develop...

Question 5

Most hurricanes have fronts.

Accepted Answer

Hurricanes are actually formed by the interaction of warm ocean waters, converging winds, and other atmospheric factors, but they do not have fronts like typical extratropical cyclones.

Question 6

Suppose the eye of a hurricane passed directly over you,and you survived the experience.If winds were from the northeast as the eyewall first approached you,from what direction did the winds blow when the eyewall reached you the second time?

Accepted Answer

As the hurricane moves, the winds in the eyewall rotate counterclockwise in the Northern Hemisphere. If the winds were from the northeast initially, they would be from the southwest when the eyewall reaches you the second time.

Question 7

Streamlines,rather than isobars,are used on surface weather maps in the tropics because they show where surface air converges and diverges.​

Accepted Answer

Streamlines show the direction of surface winds and indicate areas of convergence and divergence, which are important features in tropical weather systems. Isobars, on the other hand, indicate areas of equal barometric pressure, which may not always align with areas of wind convergence or divergence.

Question 8

A visible satellite image can be important in determining whether a developing hurricane will continue to strengthen.​

Accepted Answer

A visible satellite image can show the cloud patterns and circulation of a developing hurricane, which can give meteorologists important information on the storm's potential strength and path.

Question 9

In order for a hurricane to form,the layer of warm water must extend from the ocean surface to a depth of at least 400 meters.​

Accepted Answer

Hurricanes typically require a layer of warm water that extends to a depth of at least 26.5 degrees Celsius down to about 50 meters, not 400 meters.

Question 10

Suppose a tropical storm in the Gulf of Mexico moves westward across Central America and out over the Pacific.If the storm maintains tropical storm strength the entire time,it will be given a new name once it moves over the Pacific Ocean.

Accepted Answer

This is true. Tropical storms and hurricanes are given different names depending on their location and basin, so a storm that crosses from the Atlantic to the Pacific (or vice versa) will be given a new name once it reaches the new basin.

Question 11

North Atlantic hurricanes are more likely to form in October than in May.​

Accepted Answer

According to historical data, the peak of the Atlantic hurricane season is in September and October, with May being very unlikely for hurricane formation.

Question 12

A hurricane that once began to weaken can strengthen again,if it moves over a body of warm water.

Accepted Answer

When a hurricane moves over a body of warm water, it can absorb heat and moisture, which can cause it to intensify and strengthen again.

Question 13

Computer models of hurricanes almost always agree on their predictions of a hurricane's movement and evolution.

Accepted Answer

While computer models have advanced a lot over the years, there can still be differences in the predictions made by different models, especially when it comes to the intensity of the hurricane. Forecasters use a blend of different models to make their predictions, and they also take into account other factors such as current weather conditions and historical data.

Question 14

Streamlines on a weather map depict

Accepted Answer

Streamlines on a weather map depict the direction of wind flow, providing information on how air is moving throughout an area.

Question 15

It is impossible for a hurricane to form in the tropical North Atlantic or North Pacific during December.​

Accepted Answer

Hurricanes can form in the tropical North Atlantic and North Pacific during December, although it is less common than in other months due to cooler sea surface temperatures and a generally more stable atmosphere.

Question 16

There is a limit to the intensity of hurricanes.

Accepted Answer

Hurricanes have a maximum rating of Category 5 on the Saffir-Simpson Hurricane Wind Scale, with wind speeds over 157 mph. Therefore, there is a limit to their intensity.

Question 17

Before hurricanes and tropical storms were assigned names,they were identified according to their latitude and longitude.​

Accepted Answer

This statement is true. Before the naming system was introduced, storms were identified by their location coordinates.

Question 18

If the circumstances are right,it is possible for a hurricane to form over land.​

Accepted Answer

Hurricanes require warm ocean waters to form and cannot develop over land due to the lack of sufficient moisture and heat sources.

Question 19

Most hurricanes move westward over tropical waters.​

Accepted Answer

Hurricanes generally move westward over warm tropical waters due to the trade winds, but their path can be influenced by other weather factors.

Question 20

As it is warm all year long in the tropics,the weather is not characterized by four seasons which,for the most part,are determined by temperature variations.

Accepted Answer

The statement is true. In the tropics, there is not a significant difference in temperature between seasons, so the weather is not characterized by four distinct seasons.
