Warm Up 1. Which front moves through an area faster: Cold or Warm? 2. Which property of this front explains this rate? 3. What type of snow storm would a warm front likely bring? What is the moisture content and temperature of an air mass that formed in: 4. Maritime Polar - mP 5. Continental Arctic - cA Hint: wet or dry? cold or warm?

Warm Up 1. Which front moves through an area faster: Cold or Warm? 2. Which property of this front explains this rate? 3. If a warm front occurs in the winter, what type of snow storm would it likely bring? What is the moisture content and temperature of an air mass that formed in: (hint: wet or dry? cold or warm?) 4. Maritime Polar - mP 5. Continental Arctic - cA

Warm Up 1. Which front moves through an area faster: Cold or Warm? Cold front because warm air is easy to push 2. Which property of this front explains this speed? Cold is the “boss” = dense Warm air is less dense So the moving cold air controls what the warm air does

Warm Up 1. Which front moves through an area faster: Cold or Warm? 2. Which property of this front explains this rate? 3. If a warm front occurs in the winter, what type of snow storm would it likely bring? What is the moisture content and temperature of an air mass that formed in: (hint: wet or dry? cold or warm?) 4. Maritime Polar - mP 5. Continental Arctic - cA

Warm Up 3. If a warm front occurs in the winter, what type of snow storm would it likely bring? Light snow & long duration – same effect as rain, its just a cooler temp.

Warm Up What is the moisture content and temperature of an air mass that formed in: 4. Maritime Polar - mP 5. Continental Arctic - cA

Warm Up What is the moisture content and temperature of an air mass that formed in: 4. Maritime Polar - mP moisture = wet temp = cold 5. Continental Arctic - cA

Warm Up What is the moisture content and temperature of an air mass that formed in: 4. Maritime Polar - mP moisture = wet temp = cold 5. Continental Arctic - cA moisture = dry temp = cold

Where would the 6 different air masses originate? mA, mT, mP, cP, cT, cA mP cA cP mT cT

2.5 Understand the structure of and processes within our atmosphere Summarize the structure and composition of our atmosphere. Learning through textbook comprehension importance of yellow atmosphere assignment

2.5.2 Explain the formation of typical air masses and the weather systems that result from air mass interactions. Learning via instruction & notes Practice through questions & exit ticket Explain how air masses move (pressure differentials). Explain how interactions of air masses form frontal boundaries, clouds, and affect wind patterns.

2.5.3 Explain how cyclonic storms form based on the interaction of air masses. Write three key words from the following: Explain factors that affect air density and understand their influence on winds, air masses, fronts and storm systems. Use data for explanations and provide evidence of various air mass interactions. Address precautions for severe cyclonic storms to preserve life and property.

HurricanesTornadoes

Comparing and Contrasting Tornadoes and Hurricanes Hurricanes * Form over warm water * Greatest damage comes from storm surges and flooding *Saffir Simpson Scale 1-5 * Lose speed over land * Predictable * Big, but slow Tornadoes * Form over land usually * Greatest damage comes from winds *Fujita Scale FO-F5 * Sometimes only last seconds * Very unpredictable and fast Spinning systems of low pressure High speed winds

What is a Tornado?

How Do Tornadoes Form? Warm, humid air collides with cold, dry air The warm air rises up through the cold air creating an updraft because of a LOW PRESSURE SYSTEM If this updraft begins spinning, it can turn into a tornado

Damage Caused by Tornadoes Extremely high winds can tear buildings apart, slip cars, and even suck the water out of a riverbed Most likely during the months of April, May & June

Wait…how exactly does it form? m m Animation

Check point #1 1. What type of pressure systems are tornadoes associated with? 2. What causes the most damage during a tornado? 3. What is the intensity ranking for tornadoes?

Hurricane

FAST FACT In the Atlantic and Northeast Pacific, the term “hurricane” is used. The same type of disturbance in the Northwest Pacific is called a “typhoon” In the South Pacific and Indian Ocean “cyclones” occur

Damage Caused by Hurricanes Most from the storm surge and flooding!! Most likely to occur in Late Summer to Early Fall

FAST FACT The word “hurricane” comes from the Taino Native American word, Hurucane, meaning “evil spirt of the wind.” The first time anyone flew into a hurricane happened in 1943 in the middle of WWII.

Wait…how exactly does it form? m m

Checkpoint #2 1. What produces the most damage during a hurricane? 2. What must be true of ocean temperatures in order for a strong hurricane to form? 3. What is the intensity ranking scale for hurricanes? 4. What happens when a hurricane hits land? 5. What is the eye of the hurricane and what are the winds like IN the eye of the storm?
