HELPP FASTT i got no idea how to do this am really bad at science

Use the information above to complete this table for station A on the Gizmo.

Wind speed (knots) Wind from Cloud cover Pressure (mb)

Activity A:

Hurricane characteristics Get the Gizmo ready:
• Make sure Practice, Show hurricane, and Show weather station data are selected.

Introduction: Hurricanes form when an area of low pressure forms over warm water. Winds blow toward the low pressure, but are deflected by Earth’s rotation. The Coriolis effect causes winds to curve to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This results in a counterclockwise rotation for Northern Hemisphere hurricanes and a clockwise rotation for Southern Hemisphere hurricanes.

Question: What are some characteristics of hurricanes?

1. Observe: In which hemisphere is the hurricane shown on the Gizmo?

How do you know?

2. Describe patterns: Under Show hurricane, make sure Radar is selected. Radar is used to determine where precipitation, such as rain, is falling. Blue indicates light rainfall. Heavier rain is shown with yellow and then orange. Red indicates the heaviest rainfall.

A. Where within the hurricane is the lightest rainfall?

B. Where within the hurricane is the heaviest rainfall?

C. Describe any patterns you see in the distribution of a hurricane’s rain.

3. Observe: Under Show hurricane, select Satellite. Satellite images are taken from cameras built into satellites orbiting Earth. These images are used to study cloud coverage over large areas, including the clouds associated with a hurricane.

A. Which is larger, the area of rainfall or the area of cloud cover?

B. Where is the cloud cover most dense?

C. Where is the cloud cover least dense?

4. Identify: The center of rotation of a hurricane is called the eye. The eye of a hurricane is a core of warm, relatively calm air with low pressure and light winds. Label the eye on the hurricane at right.

5. Classify: Hurricanes are categorized based on their wind speeds. The chart at right shows the five categories used to classify hurricanes.

Move the hurricane so that the center of the storm is directly over one of the weather stations.

A. Remember one knot is equal to 1.151 miles per hour. What is the hurricane’s highest wind speed in miles per hour?
B. What category is this hurricane?

6. Observe: Move the hurricane towards another weather station. As you do this, observe the cloud cover, wind speed, and air pressure at the station.

A. How does the cloud cover change?

B. How does the wind speed change?

C. How does the air pressure change?

7. Collect data: Move a hurricane north, east, south, and west of a weather station. In the table below, record the wind direction in each case.

Hurricane position in relation to weather station Wind direction at weather station
North
East
South
West

8. Analyze: How can you tell the location of the hurricane relative to a weather station based on this information?
