Answer:

Cell circulations of the troposphere (Hadley, Ferrel, and Polar) form surface pressure belts found around the world. Seven Pressure Belts (Equatorial Low (ITCZ), Sub-Tropical Highs (2), Sub-Polar Lows (2), Polar Highs (2)) Question 2: Identify the general characteristics associated within land and sea breezes. Focus attention on the forces that give rise to differences in pressure and how this translates into changing wind directions.

Answer:

Seabreeze flows into land during the afternoon, Land breezes into sea at night. (Uneven heating of the atmosphere causes change in pressure.)

Question 3: Identify the general characteristics associated with ocean currents

Answer:

Persistent horizontal movement, at surface moved by friction from winds. Gyres - circular currents.

Question 4: Identify the characteristics associated with Mesoscale Convective Complex.

Answer:

A group a of air-mass thunderstorms form to become one big slow moving weather system.Question 5: Identify the characteristics associated with cloud-to-ground lightning.

Answer:

Requires charge separation in ground. (Only 20 % of lightning strikes.) Question 6: Identify the elements (atmospheric circulation, cyclones, and oceanic circulation) involved in the heat and moisture transfer from the equator to the poles.

Answer:

Jet streams, Tropical Cyclones, and Western boundary currents bring heat towards poles.Question 7: Know what sheet lightning is and the percentage of lighting that occurs within clouds and/or occur between clouds.

Answer:

Cloud-to-cloud lightning - light diffused by cloud (80% of all lightning strokes within clouds)

Question 8: Identify examples of instruments used to measure and/or record wind

characteristics (direction and speed of winds) at surface and at upper levels.

Answer:

Anemometer, Wind-Vane, Weather Ballons, and Doppler Radar Question 9: Identify the names of the persistent sub-tropical high-pressure belts in the Northern Hemisphere.

Answer:

Hawaiian High (Pacific Ocean), Azores High (Atlantic Ocean) Question 10: Identify the names of prominent tropical storms (hurricane) that have been retired.Focus attention on the hurricane that affected New Orleans in 2005.

Answer:

Hurricane Katrina

Question 11: Identify the general characteristics associated with winds and pressure gradients.

Answer:

Wind is caused by differences in atmospheric pressure between two locations. Isobars show pressure gradients on a map. (High to low) Question 12: Differentiate among a cold front, warm front, and an occluded front and the characteristics of each. Focus attention on the characteristics associated with a moving cold air mass.

Answer:

(Cold Front) cold air is faster than warm. (Warm Front) warm air is faster than cold air; warm front slower than cold front (Occluded Front) old air overtakes warm air and forces it upwards. (Stationary Front) two air masses in contact; little movement Question 13: Identify the characteristics associated with Mid-Latitude anticyclones.

Answer:

High pressure in center, Fair weather conditions.Question 14: Identify the area(s) of the North America where tornadoes are most likely to occur.

Answer:

Central and Southeastern United States (Tornado Alley)

Question 15: Identify the characteristics associated with a tornado.

Answer:

Rapidly rotating column of air from base of thunderstorm touching ground, Funnel dark because of water droplets, dust & debris, Extreme low pressure in center of circulation, Extreme low pressure in center of circulation.Question 16: Know what the Saffir-Simpson scale is, the number of categories, and the criteria used for categorizing tropical cyclones.

Answer:

Developed to categorize 5 different intensities of cyclones, mean wind speed and storm surge speed.Question 17: Identify the three layers of the oceanic temperature structure and the characteristics of each.

Answer:

Layer of warm water near top (Mixed Layer), Temp drops fast (Thermocline Layer), Very cold (Deep Ocean Layer)

Question 18: Identify the elements that allow Mid-Latitude Cyclones to grow over time. Focus attention on the factor that contributes the most to this growth.

Answer:

Disturbances in the jet stream that create troughs and ridges of low and high pressure, respectively, in the upper atmosphere.Question 19: Identify the two regions of the world where cyclonic tracks have been studied extensively and are well known.

Answer:

North America, and Western Eurasia Question 20: Identify the names of the persistent low-pressure belts in the Northern Hemisphere.

Answer:

Aleutian Low (North Pacific), Icelandic Low (North Atlantic) Question 21: Identify tropical cyclone hazards. Focus attention on the hazard that is the most serious.

Answer:

Storm Surge: most serious - can inundate coast (due to low pressure and high winds) Question 22: Identify the characteristics associated with the seasonal shift of winds (monsoon) that affect Asia. Focus attention on the location of pressure areas and the direction of the winds during the summer and winter months

Answer:

Monsoon: Seasonal wind shift over Asia. Summer: Intense heating creates low pressure (High pressure over oceans) Winter: Asia cools rapidly creating low pressure called Siberian High (Low pressure over oceans) Question 23: Identify the characteristics associated with cyclones and anticyclones in the upper atmosphere, respectively. Focus attention on the type of pressure, the general speed of the winds , and the direction of Coriolis and pressure gradient forces for each.

Answer:

ANTI-CYCLONE: High Pressure, Clockwise, Faster than geostrophic winds, and outward spin.CYCLONE: Low Pressure, Anti-clockwise, slower than geostrophic winds, and inward spin.
