1. Warm Up 9-15-09 Mean- the average of a set of figures. Median- the middle value in a set of statistical values. Mode- a value that has the highest frequency within a set of values. Copy notes in your Science Journal Papers and progress reports will be handed out. You are to staple all papers together with the progress report on top. Your parent needs to sign the progress report and that is all that will need to come back tomorrow. The papers will stay at your house. A signed progress report is a test grade.

2. 396.8 divided by 5= 79.36 79.3 79.3/79.5 With a partner, calculate and chart the rest of the weather data.

3. Hurricane Tracking: Storms of the 2009 Season Tropical Depression A tropical cyclone in which the maximum sustained wind speed (using the U.S. 1 minute average standard) is up to 38 mph, 17 m/s. Depressions have a closed circulation. These are named simply “Tropical Depression One” or “Tropical Depression Two”. Tropical Storm A tropical cyclone in which the maximum sustained surface wind speed (using the U.S. 1 minute average standard) ranges from 39 mph,17.5 m/s to 73 mph, 32.5 m/s. The convection in tropical storms is usually more concentrated near the center with outer rainfall organizing into distinct bands. These are named alphabetically a name from the National Hurricane Center like “Tropical Storm Mary”. Hurricane When winds in a tropical cyclone equal or exceed 74 mph, 33 m/s it is called a hurricane (in the Atlantic and eastern and central Pacific Oceans). Hurricanes are further designated by categories on the Saffir-Simpson scale. Hurricanes in categories 3, 4, 5 are known as Major Hurricanes or Intense Hurricanes. These are named alphabetically a name from the National Hurricane Center like “Hurricane Mary”.
