HES Severe Weather Objectives **You know what to do...same rules. Remember to write only your first name or web name! I have checked for correctness late Monday afternoon. Purple is correct- please don't add new material in purple!-** //Hesmaster //

1. Describe the 5 types of potential severe weather caused by severe storms.  lightening, flooding, hail, tornados, and strong winds. - elizabeth  2. What conditions are needed for a thunderstorm to develop?  cold dry air and warm wet air-Veronica 3. Thunderstorms are formed in what type of cloud? Name and describe it.  thunderstorms form in cumulonimbus clouds. cumulonimbus clouds are fluffy like cotton, hold alot of water, form long ways, dark when you are underneath them. - elizabeth  4. Explain how hail is formed and why it has a concentric structure.  hail is formed when an ice particle in a cloud goes through an updraft cycle. The top of the cloud is where the particles freeze. As the particle goes in a downward draft it picks up water and goes through the upward draft to freeze. When it gets heavy enough after repeating the cycle it breaks through and falls to the eath. The rings form on the inside of the piece of hail to show how many times it went through the cycle.-elizabeth 5. Review rules for lightning safety (indoors and outside).  indoors- stay off the phone and don't take a bath. outdoors- stay as close to the ground as possible, making the least contact with the ground as possible. crouch with your head on your knees. stay away from high ground, trees, and bodies of water. inside a car- don't touch the metal. -Veronica 6. Explain the formation of a lightning channel (induction). <span style="font-size: 10pt; color: rgb(120, 255, 0); font-family: Arial;">Induction is when there are positive charges at the top of he storm/cloud and at the bottom or land. in the middle there are the negetive charges, and when they interact a static charge occurs, or a massice static charge. this is induction. - Olga this (above) is a bit confusing and doesn’t quite grasp the idea…. <span style="color: rgb(165, 217, 150);">how about: Its a sudden flash by which the flow of electrons between oppositely charged parts of a cumulonimbus cloud or between the cloud and the ground. Its between the negative and positive charges. - Olga 7. What does a severe storm look like on a weather map? (Someone scan an image or cut and paste one from a weather map!) Label the 3 fronts.

8. What do the cloud patterns of a severe storm look like on a satellite image? (Can you find one and paste its image in here?) <span style="font-size: 10pt; font-family: 'Arial Black', Gadget, sans-serif; color: rgb(62, 8, 226);">-Julian- 9. Along what type of front does the most severe weather form? <span style="font-size: 10pt; color: rgb(0, 64, 255); font-family: Arial;">warm fronts. – <span style="font-size: 10pt; color: rgb(0, 64, 255); font-family: Arial;">elizabeth <span style="font-size: 10pt; color: rgb(0, 64, 255); font-family: Arial;">no <span style="font-size: 10pt; color: rgb(153, 51, 255);">10. What is the difference between a tornado __watch__ and a __warning__ ? <span style="font-size: 10pt; color: rgb(153, 51, 255); font-family: Arial;"> watch- the right conditions for a tornado are present. warning- there has been a sighting of a tornado, take shelter for the next 45 min. -Veronica 11. What are occluded fronts and how do they form? <span style="color: rgb(153, 142, 215);">An o <span style="color: rgb(153, 142, 215);">c <span style="color: rgb(138, 133, 209);">cluded front is formed during the process of cyclodenesis. This is when a cold front overtakes a warm front. When this occurs, the warm air is separated or “occluded”, from the cyclone center at the Earth’s surface. The point where the front and the occluded front meet (and consequently the nearest location of warm air to the center of the cyclone) is called the triple point. - Olga 12. What is a NOAA Weather radio and why is it useful? <span style="font-size: 10pt; color: rgb(153, 51, 255); font-family: Arial;"> <span style="background-image: initial; background-repeat: initial; background-attachment: initial; -webkit-background-clip: initial; -webkit-background-origin: initial; background-color: rgb(10, 10, 10); background-position: initial initial;">a NOAA weather radio is a radio that brodcast weather and natural hazards 24 hours a day and can be plugged or run on batteries it is very usefull if your in a isolated area without any electricity so that you can escape if a tornado or something is coming your way.-Deandre21 13. In order for a tornado to develop from a thunderstorm, what must happen? <span style="font-family: 'Arial Black', Gadget, sans-serif; color: rgb(38, 8, 247);">You must get a warm humid from (mainly coming from the south) and a cold front (mainly from the north) and they must collide. <span style="font-family: 'Arial Black', Gadget, sans-serif; color: rgb(38, 8, 247);">-Julian- 14. What tool do meteorologists use to determine whether there may be a tornado forming in a storm? <span style="color: rgb(0, 87, 255);"> Doppler Radar-Kara

15. Tornadoes are classified in intensity by the modified Fujita Scale. Describe it. <span style="font-family: 'Arial Black', Gadget, sans-serif;"><span style="color: rgb(40, 0, 255);">The Fujita Scale <span style="font-family: 'Arial Black', Gadget, sans-serif;"><span style="color: rgb(40, 0, 255);">is a scale for rating tornado  <span style="font-family: 'Arial Black', Gadget, sans-serif;"><span style="color: rgb(40, 0, 255);"> intensity, based on the damage tornadoes inflict on human-built structures and vegetation. -Julian- 16. Review rules for tornado safety (indoors and outside). <span style="font-family: 'Arial Black', Gadget, sans-serif; color: rgb(31, 6, 249);">If you are outdoors the best thing to do is run to shelter..If there is no shelter you should next look to jump into a ditch or a revine...If you are inside the best thing to do is to run to the center of your basement and cover your self under a sturdy table or if possible a matress. <span style="font-family: 'Arial Black', Gadget, sans-serif; color: rgb(31, 6, 249);">-Julian-
