Based on the clues in the images contained in the Sea Breeze Land Breeze folder, which of the following statements is most accurate? (Encounter Meteorology: Regional and Local Winds (Multiple Choice))

A sea breeze with relatively low pressure onshore and relatively high pressure offshore is present.

Based on the topography of the region surrounding the Highway 9 placemark, which of the following statements is most accurate? (Encounter Meteorology: Regional and Local Winds (Multiple Choice))

Alma experiences mountain breezes from the north while Blue River experiences mountain breezes from the south.

Based on the evidence in the Santa Ana Winds folder, which placemark (A - E), is the most likely location of a regional high-pressure cell? (Encounter Meteorology: Regional and Local Winds (Multiple Choice))

B

Based on the data in the Wind Potential folder, which of the following locations has the highest year-round wind generation potential? (Encounter Meteorology: Interpreting Atmospheric Pressure (Multiple Choice))

Caribbean Sea off the coast of Colombia Submit

Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer. Note that some terms will remain unused. (Give It Some Thought: Wind Direction Part A- Local Winds)

Chinook country breeze sea breeze valley breeze

Circulation in the atmosphere is influenced by whether the planetary body is rotating or nonrotating. Sort the following features by whether they apply to a rotating Earth, a nonrotating Earth, or neither. Drag the appropriate items into their respective bins. (Give It Some Thought: The Coriolis Effect, Jet Streams, and Atmospheric Flow Part A- Circulation of the Atmosphere)

Nonrotating Earth- one pair of convection cells all surface air flows toward the equator Rotating Earth- three pairs of convection cells equatorial and subpolar air flows inward and upward presence of trade winds and westerlies Neither- air sinks at the equator all surface air flows poleward

In which of the layers in the Tropical Cyclone folder do you see the best evidence of a strong low-pressure center that would indicate the presence of an active tropical cyclone? (Encounter Meteorology: Interpreting Atmospheric Pressure (Multiple Choice))

Sea Level Pressure

Which of the following statements regarding wind speeds is correct? (Encounter Geosystems: Exploration - Wind Patterns)

Some wind speeds around the center of Typhoon Songda at 24° N, 128° E on September 6 reached 144 kmph.

You are enjoying time at the beach on a warm summer day. It is late afternoon, and a breeze has started to develop. For most of the day, the winds were calm; the breeze only started within the past hour or so. Based on these details, what can you say about this breeze? Select all of the options that apply to this scenario. (Give It Some Thought: Wind Direction Part B - Developing beach winds)

The breeze is most likely a cool breeze coming from the water. Warm land has now sufficiently heated the overlying air, so that cooler air over the ocean is now moving onshore as a sea breeze.

Drag the appropriate labels to their respective targets. Note that there are twice as many blanks as answer choices. In other words, only half of the targets need to receive a label. Pay attention to the label groups and think carefully about the best position for each label when multiple locations seem possible. (Give It Some Thought: Wind Direction Part C - The importance of wind direction in airport design)

The direction planes will travel when taking off- arrow from Southwest to Northeast The correct orientation for the runway- red line southwest/northeast The location on earth where you may find a wind rose like the one shown here- NE Trade Winds around the Carribean Islands

Which of the following was the highest wind speed on September 6? (Encounter Geosystems: Exploration - Wind Patterns)

The highest wind speed was 144 kmph at 29° N, 85° W.

A jet stream generally diverges above a low-pressure (warm) center. However, at Earth's surface, air converges at a low-pressure center. If the divergence of the jet stream is greater than the convergence of air at the surface low-pressure center below it, what will happen to the surface winds? (Give It Some Thought: The Coriolis Effect, Jet Streams, and Atmospheric Flow Part B - The jet stream and surface winds)

The surface winds will likely get stronger.

Which of the following phenomena occur in the tropical South Pacific Ocean during ENSO? (GeoTutor: El Niño Southern Oscillation (ENSO) Part A - The nature of the Southern Oscillation)

Trade winds of the South Pacific weaken and may even reverse direction. Upwelling of colder ocean waters slows down near the South American coast. A low-pressure system forms over the eastern South Pacific.

Which of the following statements regarding Hurricane Frances and Typhoon Songda is correct? (Encounter Geosystems: Exploration - Wind Patterns)

Typhoon Songda had a region of 90-kmph wind that was 500 km wide on September 5.
