Question

hurricane winds student guide: what causes the winds in a hurricane? name: luz maldonado pd: 8 date: 10 - 14 - 25 analyze hurricane data 4. analyze hurricane data to see how air pressure affects the winds in a hurricane. each person in the group will select a different hurricane to analyze (choose from ian, katrina, irene, and ike). create a graph of air pressure and wind speed over time during that hurricanes lifespan. develop explanations 1. what do you notice about hurricane air pressure, wind, and storm conditions? what patterns do you see in your data? list 2. a. b. 2. how does your data compare to other members of your group? give 2 examples of things you notice. 3. explain why you think the wind speed changed when over land. use mathematic thinking and draw conclusions 4. based on your group analysis, write a summary statement describing the relationship between air pressure, wind speed, and hurricane strength. relationship between hurricane wind speed and central air pressure 5. add a line to the graph that shows the relationship between hurricane air pressure and wind speed based on your observations.

Explanation:

Step1: Analyze hurricane data

Typically, as air - pressure in a hurricane decreases, wind speed increases. This is because the pressure gradient force, which drives the wind, is stronger when the difference between the low - pressure center of the hurricane and the surrounding high - pressure areas is greater.

Step2: Compare with group data

Each hurricane may have a different rate of change of air pressure and wind speed. For example, one hurricane might have a steeper decline in air pressure with a more rapid increase in wind speed compared to another. Also, the starting and ending values of air pressure and wind speed can vary among different hurricanes.

Step3: Explain wind speed change over land

Over land, the wind speed of a hurricane decreases. This is because the land surface is rougher than the ocean surface, causing more friction. Also, the hurricane loses its main energy source, the warm, moist ocean water, which is necessary for its development and sustenance.

Step4: Write summary statement

The relationship between air pressure, wind speed, and hurricane strength is that as central air pressure in a hurricane drops, wind speed increases, and the hurricane is generally stronger. Conversely, as air pressure rises, wind speed decreases, and the hurricane weakens.

Step5: Add line to graph

Based on the inverse relationship (lower air pressure, higher wind speed), the line on the graph should slope downwards from left to right, showing that as air pressure values on the x - axis increase, wind speed values on the y - axis decrease.

Answer:

1. a. As air - pressure decreases, wind speed increases. There is often a correlation between low air - pressure and severe storm conditions.

b. The rate of change of air pressure and wind speed can vary.

1. One hurricane may have a more rapid decline in air pressure with a corresponding faster increase in wind speed. The starting and ending values of air pressure and wind speed can be different among hurricanes.
2. The land surface causes more friction and the hurricane loses its energy source (warm ocean water).
3. As central air pressure in a hurricane decreases, wind speed increases and the hurricane is stronger; as air pressure increases, wind speed decreases and the hurricane weakens.
4. A downward - sloping line from left to right on the graph to represent the inverse relationship between air pressure and wind speed.
