7 Name Class _ Date _ Name _ Cl~s _ Date _ IGraphing Skills cntinued Bar Graphs Bar graphs are useful tls fr cmparing data values. Fr example, yu might cmpare wind speeds fr trnades. The Fujita scale, which is used t measure trnad intensity, cnsiders wind speed as well as the amunt f damage caused. Trnades are ranked frm F-O t F-5, with each level having a minimum and maximum wind speed level. T create a bar graph cmparing maximum trnad wind speeds as ranked n the Fujita scale, yu wuld label six bar psitins n the x-axis with the Fujita scale rankings (F-O thrugh F-5). On the y-axis yu wuld include a range f maximum wind speeds frm 0 t 350 mph in equal increments. Then yu wuld draw bars representing the tp wind speeds fr each ranking. Yur bar graph wuld lk like the sample belw: Fujita Trnad Intensity Scale 350r ~ ~ C. 300 l ,.E. "i I ~ III 200'" "CI c: 3S E '= 50 ~ PRAcneE I I I I I I I F-O F-l F-2 F-3 Ranking Use the graph abve t answer the fllwing questins.. F-4 F-5 1. Hw much mre wind speed can an F-4 trnad have than an F-2 trnad? 3. Why d yu think there is n F-6 ranking? (This categry was prpsed fr the riginal scale.) 4. The fllwing table shws the six highest recrded temperatures in varius regins arund the wrld. Use this data t create a bar graph in the grid belw.

8 Name Date. READING A A HURRICANE'S LIFE DIAGRAM Hurricanes are brn ver Africa. The giant, swirling strms are fueled by wet weather, winds and warm cean waters. Read the diagram t learn hw hurricanes frm. Then use it t help yu answer the questins belw. After the strm Hurricanes weaken after they reach land. Sme never hit land. Instead, they turn nrtheast and die ut ver the Atlantic Ocean. Other winds help build the strm Upper- and lwerlevel winds blwing nearby in the same directin help hurricanes gain strength. Winds blwing in different directins r at different speeds can tear the strm apart. Trpical strms and hurricanes If the strm hlds tgether, a clumn-shaped eye frms at its center. Winds spin arund it, faster and faster. When winds reach 40 miles per hur, the system is called a trpical strm. When winds reach 74 miles per hur, it's a hurricane. Acrss the Atlantic Ocean Sme strms remain small. But a few gather warm cean misture, speeding up as they travel west. When bands f these thunderstrms frm a swirling pattern, the system is called a trpical depressin.
