15 Questions on Fronts and Weather Eric Angat Teacher
Warm or hot region because of its nearness to the equator. Cold region because of its nearness to the North pole. Warm & humid Cold & dry snow Polar Vortex Cold & dry hurricane
Comparing Storms and Tornadoes Storms Tornadoes Both form where air masses meet Starts above warm water. Starts on land Weakens when it reach land. Weakens when air dissipates.
Counterclockwise circulation around low pressure areas in the Northern Hemisphere. 1. What is the direction of spin of low pressure area or cyclone in the northern hemisphere?
Air rises in low pressure, making a counterclockwise spiral ( cyclone). Descending in high pressure flows in a clockwise spiral ( counter cyclone). Low pressure systemHigh pressure system 2. In the northern hemisphere, what are the directions of air in cyclone and anti-cyclone?
Tropical cyclone can be hurricanes, typhoons, and cyclones. 3. What are the three types of tropical cyclones?
Hurricanes form in the Atlantic, Caribbean Sea, Gulf of Mexico, Central and Northeast Pacific. 4. Where do hurricanes form? East Pacific Ocean Atlantic Ocean
5. Where do typhoons form? West Pacific Ocean East Pacific Ocean Atlantic Ocean Typhoons form in the Northwest Pacific ocean. Southern Atlantic
HURRICANE? CYCLONE? TYPHOON?: They're all the same, officially tropical cyclones. But they just use distinctive terms for a storm in different parts of the world.
6. The Pacific Ocean Gyre brings all the trash in center of the currents. Where are the two garbage patches located in the Pacific? Near Kuroshi, Japan Near California, USA A gyre in oceanography is any large system of rotating ocean currents, particularly those involved with large wind movements. Gyres are caused by the Coriolis Effect.
Weather fronts are where air masses meet. 7. What are weather fronts? Draw the symbol for cold front, warm front, occluded front, and stationary front.
Causes abrupt weather changes. Strong winds and severe thunderstorms. 8. What kind of weather is caused by a cold front? Cold air moves towards warm air
9. How does a cold front form? Warm air advances and replaces cold air. A.Cold air advances, forcing warm air to rise. B.Warm and cold air masses meet and mix. C.Warm and cold air masses have no relative advancement.
Stationary front moves little and rain or snow continues over a long period of time. This commonly results to flooding What kind of weather is caused by a stationary front?
11. What kind of weather is caused by a warm front? Warm air moves towards cold air If the warm air is dry, scattered clouds form. If the warm air is humid, widespread snow, showers or light rain falls.
In most cases, storms begin to weaken after a frontal occlusion occurs What kind of weather is caused by a occluded front?
13. How are hurricanes and tornadoes related to air masses? They form within air masses. A.They form where air masses meet. B.They form where air pressure is the same. C.They form where air temperatures are the same
14. What is the difference between Typhoons and Hurricanes?
CategoryWind Speed (mph)Damage at LandfallStorm Surge (feet) Minimal Moderate Extensive Extreme Over 155Catastrophic19+ Tropical cyclone categories: Classified as a super tropical cyclone, typhoon Haiyan has made landfall in the Philippines, bringing top sustained winds that were measured at more than 195 miles per hour before landfall. The measurement reflects the winds sustained by the storm for one minute; the storm was also producing gusts, abrupt rush of wind, of 230 mph. 15. What category of tropical cyclone was typhoon Haiyan? West Pacific Ocean
