All of these choices are correct

As they approach North America, hurricanes commonly move north on clockwise-curving paths due to the ___________

Coriolis Effect

Hurricanes rotate in a _____________ around a central core in the northern Hemisphere.

Counterclockwise direction

A hurricane moving over ocean water at 21 degrees C (~ 70 degrees F) would strengthen

False

A typhoon is more like a tornado than a hurricane

False

Andrew was the most destructive hurricane in US history in terms of both monetary losses and human lives.

False

As a Hurricane moves farther north, It weakens because the Coriolis effect decreases with decreases with distance from the equator

False

Hurricane centers are colder than their surroundings

False

Hurricanes often form right on the equator, because the ocean water is warmest there

False

Hurricanes that move onto land with high temperatures strengthen rapidly

False

The Fujita Scale describes the magnitude of hurricanes

False

The development of a hurricane begins with an Artic Disturbance which is low pressure zone that draws in a poorly organized cluster of thunderstorms with weak surface winds.

False

The number of people killed by hurricanes in the US increased in the later part of the 20th century.

False

Irma

Which of the following statements about hurricane Hugo is true?

A hurricane is defined as a large area of sustained winds greater than 119km/hr this is the wind speed at which

The center of the storm develops a calm area known as the eye

The main influences on tropical cyclone paths include all but which of the following?

The presence or absence of large cargo ships in their paths

Requirements for a hurricane to develop include all but which of the following?

The storm must be at least 200km from the equator

Which of the following best describes the evacuation dilemma?

There are often more people living in coastal cities than can be safely expected in less than 72 hours, potentially trapping them in traffic jams when the storm hits.

Since 1979 hurricanes and tropical storms have been given both male and female names. How are these storms named if there are more than 21 named storms in a given year?

They are named after letters in the greek alphabet, Starting with Alpha

Rank the following in order of increasing strength.

Tropical Disturbance, Tropical Depression, Tropical storm, hurricane.

A hurricane may develop from a mega-ripple in the trade winds called easterly wave.

True

Because the distinctive eye forms at wind speeds of about 119km/hr (74mph), this wind speed defines the threshold where a tropical storm has grown strong enough to be called a hurricane

True

Fronts are not associated with hurricanes

True

Hurricanes can push high mounds of seawater onshore as surges that temporarily raise sea level over 6m (20ft)

True

The energy released in a hurricane by forming clouds and rain is greater than the energy of its winds

True

The most important energy source for a hurricane is heat released by condensation of water vapor inside the storm

True

Tropical Depression is more intense than a tropical disturbance.

True

most US hurricane deaths have been associated with sea surges occurring when a hurricane moves on land

True

Inside the eye wall of a well-developed hurricane

air sinks and adiabatically warms

Hurricanes are called major hurricanes if _________

are classified as category 3 or above on the Saffir_ Simpson Scale

In a 10 year period from 2006 - 2015, the United States was ____________ for hurricanes

below average

At the top of a hurricane, upper-level air is _________ outside of the eye wall

diverging

The 2005 Atlantic hurricane season broke many all-time records, including all but which of the following?

greatest number of deaths in one season

The Saffir- Simpson Scale is used to measure the intensity of ________

hurricanes

The strongest winds in a hurricane are ________

in the eye wall

The Saffir- Simpson Scale is numbered 1 to 5 with __________ wind speeds

larger numbers indicating lower pressure and higher

The Atlantic Multidecadal Oscillation (AMO) is a reasonably distinct pattern of alternating times_________

of colder vs warm water in the North Atlantic Ocean

the danger of (northern hemisphere) storm surge is most extreme _________ of a hurricane, due to the forward motion of the storm motion and the direction of rotating winds.

on the front-right side

As a hurricane forms, the air _________________

rises, cools, and releases latent heat, further heating up the hurricanes core

Most deaths in tropical cyclones (hurricanes, typhoons etc) are the result of __________.

sea surges

The air is the eye of a hurricane _________ leaving the core clear and cloud-free

sinks, warms, and absorbs moisture

If you are on the "right hand side" of the tropical cyclone in the Northern Hemisphere you experience the ___________

speed of the storm body plus the wind speed

Hurricane surges are made worse if the coinside with a high tide at full or new moon

true

A hurricane acts as a heat engine, transferring heat from the ______________

warm, moist air above tropical seas into the core of the hurricane

As a hurricane forms, converging surface winds meet at the central core, which acts like a chimney sending _________________

warm, moist air flowing rapidly upward

As of Early 2016, Hurricane Katrina (2005) is the most costly and third most deadly natural disaster in the US since 1900. Scientists thought a hurricane strike causing a disaster like this one in New Orleans __________
