1. Standards 5a. Students know how differential heating of Earth results in circulation patterns in the atmosphere and oceans that globally distribute heat. 6a. Students know weather and climate involve the transfer of energy into and out of the atmosphere Objective 1Describe cold and warm air masses and fronts. Objective 2Describe hurricanes and tornadoes. Objective 3Understand how to read a weather map. Objective 4List tools meteorologists use and what they are for. AssessmentChapter Test ReviewDaily Bellwork, Science Starters, Standards Practice Chapter 24 Weather

2. Vocabulary Create flashcards for the following words: o Air mass o Cold front o Warm front o Stationary front o Occluded front o thunderstorm o Hurricane o Tornado o Thermometer o Barometer o Anemoter o Radiosonde o radar

4. Air Masses AIR MASS= large body of air throughout which temp. and moisture are similar 4 types: ContinentalMaritime Tropical Polar

5. Fronts FRONTS= the boundary of an air mass when 2 air masses of different temps/moisture collide COLD FRONT= when a cold air mass overtakes a warm air mass. If the warm air is moist, clouds will form and thunderstorms will result. WARM FRONT= when a cold air mass leaves, a warm front moves in. Results in precipitation over a large area. OCCLUDED FRONT=fast moving cold air mass lifts warm air off the ground

6. Severe Weather Tornadoes Rotating column of air with high winds Forms when a thunderstorm meets high altitude horizontal winds Thunderstorms Rain, thunder, lightning, strong winds Lightning=cloud s discharging electricity. Noise is Thunder. Hurricanes Develop over warm oceans Most dangerous part of hurricane is STORM SURGE; rising sea level and large waves

8. Weather Maps

9. Isobars Lines that connect points of equal atmospheric pressure

10. Isotherms Lines that connect points of equal temperature

11. Weather Instruments/INTERACTIVE Fill in the chart… Name of InstrumentWhat does it do?Other Thermometer3 types: Barometer----------------------------- Anenometer------------------------- Radiosonde---------------- Radar Doppler RadarWhat is the difference between Radar and Doppler Radar?
